以1978年配制的17个杂交组合为试验材料研究了亲本生育期、结荚习性配组方式、亲本产量水平及产量间的互作对后代选择效果的影响。1979—1983年分别种植了F_1—F_5代。试验结果表明:两亲本生育期、结荚习性的配组方式、亲本产量水平及产量间的互作对选择效果均有明显影响。并由此提出高产杂交组合适宜的亲本配组方式为:两亲本生育期差异较小,中熟×中熟或中早熟×中晚熟;亚有限×无限结荚习性或反交;两亲群体产量高,两亲产量间的互作能力强。并讨论了有关理论问题。
In this study, 17 hybrid combinations were used as experimental materials in 1978 to study the effect of parental growth period, the combination of pod habit, parental yield and yield on progenies selection. 1979-1983 were planted F_1-F_5 generation. The results showed that: the parents of parents, pod habits with the parenting group, the level of parental output and the interaction between yield on the selection effect has a significant effect. The results showed that the suitable parents of high yielding hybrid combinations were as follows: the parents had little differences in their growth stages, medium maturity, medium or medium maturity, medium and late maturing, sub-limited × infinite pods or reciprocal crosses, High, mutual productivity between the parental production capacity. And discussed the theoretical issues.
