| 摘 要： | 豌豆株粒重Y与株荚数X1、荚粒数X2、百粒重X3遗传密切相关,本试验用NCⅡ遗传交配设计研究株粒重选择指数的数量关系。结果表明,选择指数I=1.1644X1+0.3486X2+1.6031X3,指数效率为0.84,用该数量尺度指导豌豆高产育种准确有效。

| Abstract: | Grain weight per plant(Y) of pea has a close relationship with number of pods per plant(X1),number of seeds per pod(X2) and 100 seed weight(X3).NCII genetic mating was used to analyze selection index of grain weight per plant in this study.The result showed that the selection index=1.1644X1+0.3486X2+1.6031X3,with the index efficiency of 0.84,which could be useful in high yield breeding of pea. |
