| 摘 要： | 利用S1家系密植鉴定选择方法对中综6群体、瑞德群体、黄改群体、335群体进行1～2轮改良, 获得改良群体5份, 2011年进行改良效果比较试验。结果表明, 中综6群体C1、C2与C0比较单株平均产量提高5.44%、9.62%;瑞德群体、黄改群体、335群体C1与C0比较, 单株平均产量分别提高4.42%、4.68%、0.04%。同时, 改良后的群体仍保持较高的遗传变异, 有进一步改良提高的潜力。

| Abstract: | By using the S1 family planting identification of improved population methods, in Zhong Syn 6 population, Reid population, Huanggai population, Pioneer 335 population were improved. After 1-2 wheel improved, improve population 5. In 2011, the comparative experiment of yield, the results showed that Zhong Syn 6 population C1, C2 and C0 individual plant yield increased by 5.44%, 9.62%, the Reid population, Huanggai population, Pioneer 335 population of C1 and C0 comparison, individual plant yield were increased to 4.42%, 4.68%, 0.04%. Modified populations still maintain higher genetic variation, a further improvement of the potential. |
