Roasted pigs and bao dumplings: Festive food and imagined transnational identity in Chinese–Vietnamese festivals

Abstract: This article explores the ways by which special dishes prepared for the Chinese community festivals in the Vietnamese town of Hoi An negotiate and expand the notions of ethnic identity and place of origin of migrant groups. Although the festivals stress specific regional identities in (Imperial) China, the food consumed in the communal feasts defines much wider scopes of ethnicity and territory. By discussing these alternative scopes and comparing the feasts in two festivals, the article suggests that a new transnational ‘greater‐Chinese’ identity is celebrated in contemporary Chinese‐Vietnamese community festivals. The scope and importance of this new identity is analysed in relation to an imagined ‘greater‐China’ as a dominant player in the forthcoming ‘Pacific Century’. The position of the culinary sphere as a privileged arena for sociocultural negotiation, especially in post‐socialist authoritarian regimes, is also discussed.     

Participatory natural resource management in rural China: Making and unmaking environmental narratives

Environmental and development discourses in China can be categorised into three narrative motifs framing human–nature relationships: peasant, indigenous, and community. Indigenous and community narratives have been widely adopted by environmental NGOs (eNGOs) in China in promoting community‐based natural resource management projects, but there has been very limited critical research on such phenomena. Analysis of socio‐economic change in two ethnic minority communities in Yunnan shows that neither narrative theme is fully internalised by the relevant communities. Instead narratives may be strategically modified or even rejected by local communities. This is due to different agendas being held by local communities and eNGOs, and two factors pertinent to rural China: the incompatibility of concepts of ‘community’ in Chinese and international contexts results in confusion, and a lack of recent territorial and cultural claims by rural communities since the collectivist era makes it difficult to construct the identity of a community. It remains challenging for eNGOs in China to advocate either community or indigenous narratives in contexts of rapid socio‐economic change.     

Talanoa as empathic apprenticeship

Talanoa has been defined as ‘talking about nothing in particular’, ‘chat’ or ‘gossip’. It is within the cultural milieu of talanoa that knowledge and emotions are shared and new knowledge is generated. Talanoa has recently been taken up by development researchers and others as a culturally appropriate research method in Pacific contexts. However, talanoa is often treated as synonymous with ‘informal open‐ended interviews’ and tends to gloss over the deep empathic understanding required in such exchanges. Highlighting the connection between talanoa and empathy is vital in ensuring that development practitioners and researchers are implicitly aware of the political dimensions, cultural appropriacy and socio‐ecological impact of their research methods. This connection is also critical in illuminating how talanoa as a method may decolonise research in the Pacific, inform the decolonisation of research in other cultural contexts, and contribute to ethical and empowering development policy and practice. We will argue for the merits of what we refer to here as ‘empathic apprenticeship’: an intentional, embodied, emotional, and intersubjective methodology and process between the researcher and the participant. An empathic apprenticeship has the potential to enhance shared understandings between all human beings and is essential if talanoa is intended as a decolonising research methodology.     

Building knowledge city in transformation era: Knowledge‐based urban development in Beijing in the context of globalisation and decentralisation

This study examines knowledge‐based urban development in Beijing with the objective of revealing the impact of the ‘synergetic’ forces of globalisation and local government intervention on knowledge‐based urban development in the context of the coexisting processes of globalisation and decentralisation. The findings in this paper show that due to the rapid growth of the cultural industry sector, knowledge‐based urban development has created various kinds of ‘cultural industry clustered areas’, which were recently promoted by the 2008 Olympic Games. ‘Synergetic’ global and local forces are leading knowledge‐based urban development, with the emergence of a local coalition regime in which local government manages local development, considered as ‘enterprises’ in the decentralisation process, while the State retains a significant influence on knowledge‐based urban development. The central and municipal governments tend to emphasise strategies to ‘facilitate the climate for growth’ rather than the centrally planned control they exerted prior to the 1980s.     

Identification and characterization of new S‐alleles associated with self‐incompatibility in almond

Almond is a highly heterozygous species with a high number of S‐alleles controlling its gametophytic self‐incompatibility system (GSI). In this work, we have analysed 14 Spanish local almond cultivars for S‐RNase allele diversity. Five new S‐RNase alleles were identified by cloning and sequencing, S₃₁ (804 bp) in ‘Pou de Felanitx’ and ‘Totsol’, S₃₂ (855 bp) in ‘Taiatona’, S₃₃ (1165 bp) in ‘Pou d’Establiments’ and ‘Muel’, S₃₄ (1663 bp) in ‘Pané‐Barquets’ and S₃₅ (1658 bp) in ‘Planeta de les Garrigues’. Additionally, seven already known almond alleles could be recognized in the local cultivars studied. The high number of new alleles identified reveals the wide diversity of almond germplasm still existing and requiring characterization, and points to the possibility of new findings by a wider study focusing on other provenances. The almond S‐RNases have been compared to those of other Prunus species, showing a high identity and confirming that the S‐RNase gene in this genus presents a probable common ancestor.     

An asset‐based approach to indigenous development in Taiwan

Numerous scholars studying community efforts to (re‐)establish autonomy have begun to focus on the importance of empowerment in the economic, political and cultural spheres. There is a growing understanding that such empowerment can be hastened by affirmative development strategies that build on community assets and capacities rather than attempting to redress – and thereby emphasising – needs or lack. Such development work reflects intertwined currents in contemporary philosophy, influenced by the thought of Friedrich Nietzsche and of Gilles Deleuze. In Taiwan, a recent resurgence in identities among marginalised aboriginal or indigenous peoples (‘Formosans’) has been accompanied by novel approaches to development. This discussion heuristically employs a set of development theories that are essentially variants of ‘asset‐based community development’ (ABCD) to suggest that a focus on affirmation and empowerment has been and can be a key to success in Formosan development initiatives. The paper presents the results of qualitative field research, illuminating three case studies of Formosan development – in Tsou, Tayal and Taroko territories. It argues that Formosan development will benefit from a focus on community capacity, political empowerment and social as well as physical assets, and that to an important degree this has already happened in some communities.     

Evaluation of cold hardiness in two sets of near-isogenic lines of wheat (Triticum aestivum) with polymorphic vernalization alleles

In wheat, variation at the orthologus Vrn‐1 loci, located on each of the three genomes, A, B and D, is responsible for vernalization response. A dominant Vrn‐1a allele on any of the three wheat genomes results in spring habit and the presence of recessive Vrn‐1b alleles on all three genomes results in winter habit. Two sets of near‐isogenic lines (NILs) were evaluated for DNA polymorphisms at their Vrn‐A1, B1 and D1 loci and for cold hardiness. Two winter wheat cultivars, ‘Daws’ and ‘Wanser’ were used as recurrent parents and ‘Triple Dirk’ NILs were used as donor parents for orthologous Vrn‐1 alleles. The NILs were analysed using molecular markers specific for each allele. Only 26 of 32 ‘Daws’ NILs and 23 of 32 ‘Wanser’ NILs had a plant growth habit that corresponded to the marker genotype for the markers used. Freezing tests were conducted in growth chambers programmed to cool to ?21.5°C. Relative area under the death progress curve (AUDPC), with a maximum value of 100 was used as a measure of death due to freezing. The average relative AUDPC of the spring habit ‘Daws’Vrn‐A1a NILs was 86.15; significantly greater than the corresponding winter habit ‘Daws’Vrn‐A1b NILs (42.98). In contrast, all the ‘Daws’Vrn‐A1bVrn‐B1aVrn‐D1b and Vrn‐A1bVrn‐B1bVrn‐D1a NILs (spring habit) had relative AUDPC values equal to those of their ‘Daws’ sister genotypes with Vrn‐A1bVrn‐B1bVrn‐D1b NILs (winter habit). The average AUDPC of spring and winter habit ‘Wanser’ NILs differed at all three Vrn‐A1, Vrn‐B1 and Vrn‐D1 locus comparisons. We conclude that ‘Daws’ and ‘Wanser’ have different background genetic interactions with the Vrn‐1 loci influencing cold hardiness. The marker for Vrn‐A1 is diagnostic for growth habit and cold hardiness but there is no relationship between the Vrn‐B1 and Vrn‐D1 markers and the cold tolerance of the NILs used in this study.     

Early-bolting trait and RAPD markers in the specific monosomic addition line of radish carrying the e-chromosome of Brassica oleracea

The specific monosomic addition line of radish, Raphanus sativus, carrying the e chromosome of Brassica oleracea (2n = 19, e‐type MAL) with the genetic background of the late‐bolting cv.‘Tokinashi’ was produced by successive backcrossing of the original e‐type MAL of radish that showed early bolting in the genetic background of the cv. ‘Shogoin’. The early‐bolting trait specific to the e‐type MAL was constantly expressed in the backcrossed progenies (BC₂, BC₃ and BC₄), whereas the reverted radish‐like plants (2n =18) were gradually converted to bolting as late as ‘Tokinashi’. The added e‐chromosome expressed an epistatic effect against the genome of Japanese radish. Its early‐bolting trait was dominant to the late‐bolting trait of ‘Tokinashi’ which may be under the control of a few genes. Moreover, e‐type specific RAPD markers detected in eight primers were invariably transmitted in the backcrossed progenies by ‘Tokinashi’. From the analysis of the characteristics to the e‐type MAL and e‐type specific RAPD markers, it is suggested that the e‐added chromosome of kale (B. oleracea) was transmitted from generation to generation without any recombination with the radish chromosome. The gene(s) for the early‐bolting trait detected in this study may be useful for breeding work in radish, especially in the tropical areas.     

Molecular markers for Ve1 and Ve2 Verticillium resistance genes from Italian tomato germplasm

The so‐called Rosa (= pink) tomatoes, which are typically grown in the Southern Italian area, are characterized by the pink colour of the fruit, due to the gene y, colourless fruit skin. In a preliminary survey, it was found that among these Rosa tomatoes there were some ‘Rosa di Sorrento’ local landraces showing resistance to Verticillium wilt (race 1). In tomato, resistance to race 1 of V. dahliae and V. albo‐atrum is conferred by two strictly associated genes, Ve1 and Ve2, which independently confer resistance to the same pathogen. The development of two new markers for Ve1 and Ve2, based respectively on selective allele‐specific PCR amplification and on a PCR amplification followed by enzymatic restriction, is reported. These two markers allow the identification of both allelic forms at the Ve loci and they are of potential interest for use in marker‐assisted selection. Furthermore, ‘Rosa di Sorrento’‐resistant lines have the same resistance alleles as those found in the Ve‐resistant cultivars.     

The linkage between the stem rust resistance gene Sr2 and pseudo-black chaff in wheat can be broken

Recessively inherited gene Sr2 has provided the basis of durable resistance to stem rust (caused by Puccinia graminis tritici) in wheat (Triticum aestivum L.) worldwide. The associated earhead and stem melanism or ‘pseudo‐black chaff’ is generally used as a marker for this gene. Sr2 has been postulated in many wheat cultivars of India including ‘Lok 1’, based on associated pseudo‐black chaff in adult plants, and leaf chlorosis in seedlings. However, dominant inheritance of the resistance factor operating in ‘Lok 1’, and a 13 : 3 (resistant : susceptible) F₂ segregation in the ‘Sr2‐line’ (‘Chinese Spring’⁶ × ‘Hope’ 3B) × ‘Lok 1’ cross confirmed that Sr2 was absent in ‘Lok 1’. Susceptible plants with a pseudo‐black chaff phenotype were observed in F₂ populations of ‘Agra Local’ (susceptible) × ‘Lok 1’, and the ‘Sr2‐line’ × ‘Lok 1’ crosses. Most of the F₃ families derived from the susceptible F₂ segregants with pseudo‐black chaff phenotypes were true breeding for the expression of pseudo‐black chaff with susceptibility to stem rust. Thus, linkage of pseudo‐black chaff with Sr2 in wheat can be broken, and hence, caution may be exercised in using pseudo‐black chaff as a marker for selecting Sr2 in breeding programmes.     

Fine mapping of qSS‐9, a major and stable quantitative trait locus,for seed storability in rice (Oryza sativa L.)

Seed storability in rice (Oryza sativa L.) is an important agronomic trait. We previously showed a quantitative trait locus of seed storability, qSS‐9, on chromosome 9 in a backcross population of ‘Koshihikari’ (japonica) / ‘Kasalath’ (indica) // ‘Koshihikari’. In this study, fine mapping of the chromosomal location of qSS‐9 was performed. Effect of ‘Kasalath’ allele of qSS‐9 was validated using a chromosome segment substitution line, SL36, which harboured the target quantitative trait loci (QTL) from ‘Kasalath’ in the genetic background of ‘Nipponbare’ under different ageing treatments in different environments. Subsequently, an F₂ population from a cross between ‘Nipponbare’ and SL36 was used for fine mapping of qSS‐9. Simultaneously, four subnear isogenic lines (sub‐NILs) that represented different recombination breakpoints across the qSS‐9 region were developed from F₃ progeny. Finally, the qSS‐9 locus was located between the Indel markers Y10 and Y13, which delimit a region of 147 kb in the ‘Nipponbare’ genome. These results provide a springboard for map‐based cloning of qSS‐9 and possibilities for breeding rice varieties with strong seed storability.     

Inheritance of tolerance to zinc deficiency in barley

Barley (Hordeum vulgare L.) is often grown on alkaline zinc (Zn)‐deficient soils where reductions in yield and grain quality are frequently reported. Currently, the use of Zn‐based fertilizer along with Zn‐deficiency‐tolerant genotypes is considered the most thorough approach for cropping the Zn‐deficient soils; however, developing or breeding genotypes with higher Zn efficiency requires a good understanding of the inheritance of tolerance to Zn deficiency. This study was conducted to determine genetic control of this trait in barley. Two parental cultivars ('Skiff, moderately tolerant; and ‘Forrest’, sensitive), 185 F₂ plants, and 48 F₂‐derived F₃ families from this cross were screened to determine inheritance of tolerance to Zn deficiency using a visual score of deficiency symptoms. The segregation ratios observed indicated that greater tolerance to Zn deficiency in ‘Skiff compared with ‘Forrest’ at the seedling stage is controlled by a single gene with no dominance. The results also indicate that visual scores are useful for genetic analysis of tolerance to Zn deficiency.     

Creating community‐based indicators of gender equity: A methodology

It appears that an almost unquestioned development pathway for achieving gender equity and women's empowerment has taken centre stage in mainstream development. This pathway focuses on economic outcomes that are assumed to be achieved by increasing women's access to material things, including cash income, loans, physical assets, and to markets. Gender equity indicators, which measure progress towards these outcomes, cannot escape reinforcing them. We argue that far from being neutral, indicators are embedded in political and ideological agendas that serve as guides to the appropriate conduct of those whose performance or behaviour is being measured. Drawing on participatory feminist, diverse economies and strengths based approaches, we outline a research methodology for developing community‐based indicators that recognises women's and men's participation and relationships in all spheres of life, including the ‘non‐economic’. If indicators are grounded in local meanings and realities, we propose that community members can use them to identify aspirational goals for gender equity, and measure progress towards these goals.     

Forced evictions,spatial (un)certainties and the making of exemplary centres in Indonesia

This article considers the relationship between forced evictions and the ‘exemplary centre’ through an examination of three urban waterfront sites in Indonesia in comparative perspective. How is the notion of the ‘exemplary centre’ related to forced evictions and the aspirations of marginalised populations in contemporary cities of Indonesia? What are the chances of asserting alternative ideologies when a capital‐centric and modernist vision of the city as ‘exemplary centre’ dominates official planning paradigms? Competing visions of the ‘exemplary centre’ arise from distinct centres of power, from the state level to the grassroots community level; however, the dominant state vision of urban space is often internalised by those most at risk of displacement by modernist projects. Strategies to thwart forced evictions in riverbank settlements in Jakarta, Solo, and Surabaya offer alternative imaginings of the ‘exemplary centre’ – imaginings that enable the urban poor to visualise their hopes and to overcome the spatial uncertainties that characterise their everyday lives. While these efforts indicate resistance to marginalisation, they also provide a distinct kind of ‘exemplary’ vision based on residents’ own understanding of ideal city living. Concurrently, some alignment to existing ‘exemplary centre’ narratives is traceable in the effort to assert these alternatives.     

Analysis of diallel crosses between wheat genotypes with genetically different resistance to Pseudocercosporella herpotrichoides (Fron) Deighton

Two diallels were analysed for general combining ability (GCA) and specific combining ability (SCA) to study the resistance of crosses‐between wheat genotypes, advanced to the F₅ generation, to Pseudocer‐cosporella herpotrichoides. The parents either carried the resistance‐gene Pch‐1 or had different levels of quantitative resistance, one genotype was susceptible. At medium milk‐ripening, significant effects were‐found for GCA and SCA. GCA effects were the more important. Diallel crosses between genotypes, all carrying Pch‐1, revealed interactions‐of the gene with the genotypic background. Some combinations had a‐higher level of resistance than the best parent. In these populations'CH‐75417’ was involved as a parent. Both ‘CH‐75417’ and ‘F–210.13.4.42’ had significant GCA effects. Crosses between quantitatively resistant parents yielded populations that transgressed both parents. The increased resistance level was associated with ‘Cappelle‐Desprez’, distinguished by its high GCA. In some crosses SCA contributed significantly to an increase in resistance level. Selection for resistance within the best advanced populations is recommended since it‐takes advantage of additive gene action and the high heritability estimates based on ELISA values in plant progenies.     

The Physiology and Stability of Leaf Carbon Isotope Discrimination as a Measure of Water‐Use Efficiency in Barley on the Canadian Prairies

Temporal and seasonal water deficit is one of the major factors limiting crop yield on the Canadian prairie. Selection for low carbon isotope discrimination (Δ¹³C) or high water‐use efficiency (WUE) can lead to improved yield in some environments. To understand better the physiology and WUE of barley under drought conditions on the Canadian prairie, 12 barley (Hordeum vulgare L.) genotypes with contrasting levels of leaf Δ¹³C were investigated for performance stability across locations and years in Alberta, Canada. Four of those genotypes (‘CDC Cowboy’, ‘Niobe’, ‘170011’ and ‘Kasota’) were also grown in the greenhouse under well‐watered and water‐deficit conditions to examine genotypic variations in leaf Δ¹³C, WUE, gas exchange parameters and specific leaf area (SLA). The water‐deficit treatment was imposed at the jointing stage for 10 days followed by re‐watering to pre‐deficit level. Genotypic ranking in leaf Δ¹³C was highly consistent, with ‘170011’, ‘CDC Cowboy’ and ‘W89001002003’ being the lowest and ‘Kasota’‘160049’ and ‘H93174006’ being the highest leaf Δ¹³C. Under field and greenhouse (well‐watered) conditions, leaf Δ¹³C was significantly correlated with stomatal conductance (g_s). Water deficit significantly increased WUE, with ‘CDC Cowboy’– a low leaf Δ¹³C genotype with significantly higher WUE and lower percentage decline in assimilation rate (A) and g_s than the other three genotypes (‘Niobe’, ‘170011’ and ‘Kasota’). We conclude that leaf Δ¹³C is a stable trait in the genotypes evaluated. Low leaf Δ¹³C of ‘CDC Cowboy’ was achieved by maintaining a high A and a low g_s, with comparable biomass and grain yield to genotypes showing a high g_s under field conditions; hence, selection for a low leaf Δ¹³C genotype such as ‘CDC Cowboy’ maybe important for maintaining productivity and yield stability under water‐limited conditions on the Canadian prairie.     

A leaf rust resistance gene, different from Lr34, associated with leaf tip necrosis in wheat

The gene Lr34 has contributed to durable resistance to leaf rust caused by Puccinia triticina in wheat worldwide. The closely associated leaf tip necrosis is generally used as the gene's marker. Lr34 has been postulated in many Indian bread wheat cultivars including ‘C 306’, based on the associated leaf tip necrosis and a few other field and glasshouse observations. The present study showed monogenic control of adult‐plant resistance in ‘C 306’ to leaf rust pathotype 77‐5 (121R63‐1). The F₂ segregation in the crosses between ‘C 306’ and the two known carriers of Lr34, ‘Line 897’ and ‘Jupateco 73’‘R’ fitted a digenic ratio. The F₃ families derived from the susceptible F₂ segregants were true breeding for susceptibility, proving the absence of Lr34 in ‘C 306’. The cross between ‘Line 897’ and ‘Jupateco 73’‘R’ did not segregate for susceptibility. Resistance in the cross ‘Agra Local’ (susceptible) × ‘C 306’ was associated with leaf tip necrosis, showing that the leaf rust resistance gene in ‘C 306’ was associated with leaf tip necrosis, but was different from Lr34. This gene is being temporarily designated as Lr‘C 306’. Hence, leaf tip necrosis cannot be considered as an exclusive marker for selecting Lr34 in wheat improvement.     

RFLP analysis allows for the identification of alfalfa ecotypes

Three seed lots, obtained from different ‘foundation farms’, for each of the alfalfa, Medicago sativa L., ecotypes ‘Vogherese’ and ‘Maremmana’, together with the variety ‘Iside’ as a control, were studied to test the possibility of distinguishing them through restriction fragment length polymorphism analysis. Twenty plants per seed lot were analysed with 25 DNA probes that yielded 155 informative polymorphic fragments. Variance partitioning showed that within‐population variability accounted for nearly 98% of the total variance, while a small but significant contribution to the total variance was due to among‐lot variability.‘Vogherese’ was more homogeneous than ‘Maremmana’, as a consequence of the greater environmental homogeneity of the adaptation area of the former ecotype compared with the latter. Bulk analysis yielded eight variety‐specific bands, 12 bands present in both ecotypes and absent in the variety and one band specific of ‘Maremmana’. Results are discussed in relation to the practical use of molecular markers for alfalfa ecotype identification.     

Genetic analysis of resistance to green leafhopper, Nephotettix virescens (Distant), in three varieties of rice

The genetics of resistance to green leafhopper, Nephotettix virescens (Distant), in rice varieties ‘IR36’ and ‘Maddai Karuppan’ and breeding line ‘IR20965‐11‐3‐3’ was studied. The reactions of F₁ hybrids, F₂ populations and F₃ lines from the crosses of test varieties with the susceptible variety ‘TN1’ revealed that resistance in ‘IR36’ and ‘Maddai Karuppan’, is governed by single recessive genes while resistance in ‘IR20965‐11‐3‐3’ is controlled by a single dominant gene. Allele tests with the known genes for resistance to green leafhopper revealed that the recessive gene of ‘IR36’ is different from and inherited independently of Glh1, Glh2, Glh3, Glh4, Glh5, Glh8 and Glh9t. This gene is designated as glh10t. The recessive gene of ‘Maddai Karuppan’ and the dominant gene of ‘IR20965‐11‐3‐3’ are also non‐allelic to Glh1, Glh2, Glh3, Glh4, Glh5 and Glh8t. Thus, the dominant gene of IR20965‐11‐3‐3 is designated as Glh11t. The allelic relationships of the recessive gene of ‘Maddai Karuppan’ with glh8 and glh10t should be investigated.
