| 摘 要： | 本文遗传相关通径分析结果如下:穗长、穗粒重两性状对小区产量直接影响较大;每穗实粒数和每穗不实粒数两性状对小区产量直接影响很小,但通过其他性状对小区产量的间接负影响很大;每穗总粒数对小区产量直接负影响很大;株高通过其他性状对小区产量间接正影响很大。

| Abstract: | Through the heretability correlation coefficient path analysis,We have obtained the results as follows: Fringe length and grain weight Per ear, these two characteristics, have a considerable direct effect on little area yield; effective grain number Per ear and nonbearing grain numberPer ear, these two characteristics, have little direct effect but throughother characteristics exercise considerable indirect negative effect. Effective grain number has direct negative effect on little area yield. Plant height through characteristics has indirect Positive effect on little areayield. |
