摘  要：
本试验采用雄性核不育大豆互交群体RS6Y研究了南京和Raleigh异地产量轮回选择响应在南京的表现。结果表明 ,南京选择的二轮群体均与基础群体的产量存在显著差异 ,两轮分别增产9.4 5 %和 5 .6 3% ,改良效果比较好。Raleigh选择群体与基础群体间的产量差异没有达到显著水平 ,但两轮选择后产量提高了 5 .2 4 %。不同地区之间的选择效果差异较大 ,南京选择的效果显著高于Raleigh选择的效果。产量选择对蛋白质含量、脂肪含量的影响不大 ;单株产量、单株荚数、单株粒数、株高和主茎节数增加 ,百粒重下降 ,但均未达到显著水平。产量选择伴随农艺性状遗传变异度的降低 ,可能与该互交群体的遗传变异度相对较小有关

摘  要：
The differential responses to yield recurrent selection under Nanjing and Raleigh conditions on ms 1 intermiting population RS6Y were evaluated in Nanjing in 1995,1996 and 1998. The significant yield increases after first and second cycle yield recurrent selection in Nanjing were obtained as 9.45% and 5.63% , respectively, while only 5.24% total increase ,but not significant was obtained after two cycles selection in Raleigh when they were tested in Nanjing. It indicate the differential responses to selection under different ecological conditions at various sites were concluded. There was no significant indirect selection response on agronomic and seed quality traits, including protein content and oil content. However, there appeared increase on plant height, No.of nodes, single plant yield, number of pods per plant, number of seeds per plant, and some decrease on 100-seed weight, but not significant. There also appeased some decrease of genetic variation in agronomic traits under yield recurrent selection, which should be further studied.
