摘要
16个乌桕表型优良无性系遗传测定结果表明:各无性系间在单位面积种子产量、单序果数、千粒重、皮油率、梓油率、种子总含油率、单位面积产油量等方面均存在着极显著差异;单序果数、千粒重、单位面积种子产量、种子总含油率等性状的无性系广义遗传力较高,通过选择可获得较高的遗传增益。本文通过3点试验、方差分析和聚类分析等方法,从初选的16个无性系中进一步选择出经济性状综合表现优良的PC03、PC06、PC05、JY01等4个无性系。
The results of sixteen primarily selected superior clones of genetic tests of Sapium sebiferum showed that there were very significant differences in seed production per unit area, per-cob fruit integer, thousand grain weight(TGW), gross oil rate, net oil rate oil production of seed (OPS), oil production per unit area among all clones. The clonal broad heritability of per-cob fruit integer, thousand grain weight, seed production per unit area and oil production of seed (OPS) was high, the high genetic gain ...
