Juvenile radiata pine clonal seed orchard management in Galicia (NW Spain)

A juvenile radiata pine clonal seed orchard (Pinus radiata D. Don) in Sergude (northwestern Spain), comprising 57 clones, was evaluated for fertility, offspring diversity and genetic drift during 4 years. Flower and fruit production was used to asses clone fertility in the orchard. Fertility variation measured as “sibling coefficient” was found to be an average of 1.5, having high genetic diversity (0.99) and low coancestry (0.013). The clones varied in fertility from year to year. Effective population size in the orchard was between 35 and 40, indicating that between 60.30 and 69 %, the clones contributed effectively to seed yield. One way to improve seed yield in the orchard is by increasing the effective population size. Thinning and pruning highly reproductive clones of gibberellin application might be useful in increasing effective population size. The orchard’s parental balance showed consistent improvement over time. Cone and seed characteristics were also investigated. The results showed that significant genetic variation exists among clones for cone width and length; total, sound and empty seed number; as well as 100 seed weight. The seed orchard is still in a juvenile phase; moreover, the broad-sense heritability and variation data obtained in this study could be very valuable in the management practices of the existing radiata pine clonal seed orchard and can be also used for better planning of advanced generation of clonal seed orchards in Spain.     

Cost-benefit analysis of using orchard or stand seed in Scots pine sowing,the case of northern Finland

A cost-benefit analysis of orchard seed versus seed from existing natural stands is presented for the scenario of direct sowing of Scots pine (Pinus sylvestris L.). The differential benefits of orchard seed are seed quality and improved yield due to genetic gain. These benefits are expected to further reduce the total cost of orchard seed. Seedlings from seed orchard seed had 11% better survival rate (p < .001, the best clone over 17%, p < .010) than seedlings from local stand seed. This was observed in a case study of 15 young seeding trials located in Central and North Finland. Expected yield improvements for stands established with orchard seed were obtained from local progeny test results, and they were further simulated on tree growth using the MELA forest simulation program. The cost-benefit analysis showed that, with a 7% yield improvement and a 15% better seed quality, the net cost of orchard seed was less than that of stand seed (discount rate 3%).

Genetic divergence for growth and wood parameters in different clones of Dalbergia sissoo Roxb

The wood analysis for different parameters was carried out in a clonal seed orchard of Dalbergia sissoo Roxb. established during 1997 at Hoshiarpur, Punjab, India. Twelve clones with higher index value were subjected to Euclidean Cluster Analysis based on wood and growth parameters to group into seven clusters. Cluster I and II contained four and three clones, respectively, and remaining clusters had just one clone each. Clone originated from Barielly, Uttar Pradesh of cluster VII was found to be the most divergent clone. Cluster II with three clones maintained greater inter-cluster distance with other clusters. The divergence analysis has confirmed that the clones planted in the clonal seed orchard are sufficiently divergent and seed harvested from the orchard would maintain high diversity.     

马尾松人工群体交配系统研究

借助水平淀粉凝胶电泳同工酶分析方法，研究了马尾松一无性系种子园，该种子园附近一人工林，马尾松－优树收集区的交配系统。研究结果表明，该种子园的多位点异交率为：０．７９２（ＳＥ＝０．０６２），种子园中心区与边缘区的多位点异交率分别为：０．８０１（ＳＥ＝０．０７５），０．８００（ＳＥ＝０．０６７）；种子园附近人工林的多位点异交率为：０．８２１（ＳＥ＝０．１８８），优树收集区的多位点异交率为：０．４３１（ＳＥ＝０．１３１）。说明该马尾松种子园的异交率较低，这可能成为影响种子园种子产量和种子质量的一个制约性因子。文章讨论了影响群体交配系统的主要因子，分析了马尾松异交率较低的可能原因，并对这一方面的进一步研究提出了一些建议。
