摘 要 ：本文通过对17个粳稻品种和 F_1及 F_2各3个杂交组合,进行粳稻叶型的遗传与选择的研究,经3年的试验结果:一、通过对杂交后代的遗传动态分析,表明粳稻剑叶的开张角、长和宽皆为多基因控制的数量遗传;二、通过对遗传力和相关系数的估算,表明剑叶宽、基角和开张角的遗传力较高,特别是剑叶开张角的相对遗传进度也较高,并与叶的长、

Abstract:Experiments on inheritance and selection of the leaf shape in Kengrice were conducted with 17 cultivars and 3 combinations each for F_1and F_2 during 1980-1982,the results were as follows:1)With the analysis of inheritanco of hybrid progenies,it showedthat the obtuse angle(angle between the main ste
