More than one-third of the world's population is afflicted by iron (Fe) and zinc (Zn) deficiencies, since cereal grain as a staple food of the people contains low levels or low bioavailability of Fe and Zn because of phytate. In maize, 80% of grain phosphorus (P) is in the form of phytate, and P could be an indicator of phytate content. The objectives of this study were (1) to estimate genetic variation of Fe and Zn in a maize population including P/Fe and P/Zn molar ratios as quantitative traits; (2) to determine relations among yield, P, Fe, Zn, P/Fe and P/Zn molar ratios; and (3) to define the implications of those on biofortification (breeding) programmes. There were significant genetic variations and workable heritabilities for Fe, Zn, P/Fe and P/Zn estimated in 294 F4 lines of a maize population, but there were no associations among six traits according to both simple correlations and principal component analysis. Weak correlations between P and Fe and between P and Zn indicated feasibility of breeding non low-phytic acid maize genotypes with more appropriate phytate/Fe and phytate/Zn relations. Bioavailability of iron and zinc varied substantially in a maize population justifying utilisation of these unique parameters in biofortification programmes. 相似文献

Growing numbers of candidate varieties, decrease of their variability for morphological traits, and internationalization of
the national list all contribute to excessive increase of the trial costs, thus creating the need for the improvement of current
variety evaluation procedures, especially regards their distinctness, Uniformity, and Stability (DUS) component. Due to rapid
advancement in molecular techniques, the use of molecular markers in DUS testing as a complement to, or replacement of, morphological
observations became the subject of great interest in scientific studies, and consequently topic for discussion within International
Union for the Protection of New Varieties of Plants (UPOV). In order to explore the potential of simple sequence repeat (SSR)
markers for distinctness tests, present study involved set of 41 maize inbred lines that were scored for 32 DUS characters
prescribed by UPOV and genotyped at 28 SSR loci. Results were largely in favor of the use of molecular markers, revealing
or confirming their already known advantages over morphological markers like better consistency with the pedigree, and relatively
higher discriminative power. However, their integration into DUS testing protocols still depends upon resolving of several
important issues. 相似文献
