摘 要 ：用双列分析的方法研究了陆地棉(Gossypium hirsutum L.)4个品种及其杂种 F_1的种仁油分和氨基酸成分的资料,分析了杂种优势的表现和遗传效应,并估算了棉子性状间的简单相关系数。F_1的种仁含油率表现正的平均优势(4.75%),种仁氨基酸总量表现负的平均优势(-3.60%)。这两个性状的显性方差(H_1、H_2)都远大于加性方差(D),表明它

Abstract:The oil and amino acid contents in seed kernel of four parents andtheir F_1 hybrids in upland cotton(Gossypium hirsutum L.)were studiedby diallel analysis.Heterosis and genetic effects of these traits wereanalysed,and correlation coefficients among some seed traits were alsoestimated.There were posi
