红松优树子代多点测定综合分析

Synthetic Analysis on Multi-site Determination of Filial Generation for Korean Pine Elite Tree

对红松自然分布区内3个亚区、9个产地、108个家系优树子代3个试验点10年生树高测定表明，亚区间、产地/亚区间差异显著，家系/产地/亚区×地点间差异极显著。北亚区优树子代在带岭和露水河两地表现最好，南亚区在草河口表现最好。9个产地综合评定带岭优树子代表现最好。108个家系有87个超过对照，占参试总数80.5%；达显著水准有5个，占参试总数4.6%，超过对照34%以上。

The heights of ten-year-old filial generations of Korean pine elite trees from 3 sub-areas, 9 provenances, 108 families within the natural distribution range were determined. The results showed that the difference among sub-areas and the difference between provenances and sub-areas were all significant, and the differences between families, provenances, sub-areas and sites were extremely significant. The behavior of filiar generation from northern sub-area was the best growing in Dailing and Lushuihe, and those from sourthern sub-area were the best growing in Caohekou. Synthetic evaluation of 9 provenances showed that the filial generation of elite trees from Dailing was the best. Within 108 families, 87 families surpassed the contrast test, accounting for 80.5% of the sum total of participants; 5 families reached significant level, accounting for 4.6%, and exceeded the contrast test by 34%.
