| 摘 要： | 1980～1983年对高粱叶片角度的遗传传递规律以及叶角与其它株型性状之间的相关性进行了研究,表明叶片角度的遗传最少受4对等位基因控制,属于数量性状,广义遗传力在70～90%之间,狭义遗传力在80%以上。叶角与株型的其它各性状之间无明显相关而独立遗传。在株型育种中,从早代起就进行叶角的选择,可获得良好的效果。 |

| Abstract: | The genetic law of leaf angle in sorghum(Sorghum bicolor(L.)Moench)and correlation between the leaf angle and other characters onsorghum plant type were studied in 1980-1983.The results showed that the heredity of leaf angle in sorghum werecontrolled by at least fours pairs of alleles which belong to the quantitative charactes.The general genetic capacity was between 70 and 90percent and the restricted genetic capacity was over 80 percent.Therewere no significant relationship between the heredity of leaf angle and othercharacters of plant type,but the heredity of leaf angle would take placeindependently For the breeding programs on sorghum plant type,the betterresults of selections of leaf angle can be obtained from early progenies. |
