| 摘 要： | 通过对6个粳稻杂交组合F2代6个产量性状的遗传相关、遗传参数、通径分析及选择指数的研究,结果表明:在早期世代对每穗粒数、有效穗数、单穗重及单株谷重进行综合选择,对产量的遗传进展有较好的效果。

| Abstract: | Study on the genetic correlation, genetic parameter, path analysis and selection index of six yield traits of F2 in six different Japonica Crosses. The results indicated that complex select spikelets per panicle, weight per panicle and grain weight per plant in early generations. It is better effect to increase genetic anvance. |
