【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。更多还原

【Abstract】 By using the S 1 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 C 1, C 2 and C 0 individual plant yield increased by 5.44%,9.62%,the Reid population,Huanggai population,Pioneer 335 population of C 1 and C 0 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.更多还原
