选用６个种间杂交种质系作母本，４个陆地棉常规品种作共同父本，按３×４不完全双列杂交设计配制两种类型的组合２４个，分析了１０个性状的杂种优势和配合力效应。结果表明，子、皮棉产量的优势最大，其次是单株铃数，而其余产量性状的优势表现较弱。纤维品质性状的优势亦较大。陆瑟海种质系×陆地棉的子、皮棉产量和品质性状的综合性较突出，均达显著水平。配合力分析结果也表明，（陆瑟海种质系×陆地棉）组合间的变异主要受基因控制，多数性状具有显著或极显著的亲本ＧＣＡ和组合ＳＣＡ差异。
Six interspecific hybrid germplasms were selected as the female parent and the four genic cotton cultivars as common paternal parents. According to 3 × 4 incomplete diallel crosses, 24 combinations of two types were selected and 10 hybrids Advantage and combining power effect. The results showed that the yield of lint and lint had the biggest advantage, followed by the number of bolls per plant, while the performance of other yield traits showed weaker performance. Fiber quality traits have greater advantages. Luceri germplasm × Upland cotton son, lint yield and quality traits more prominent, reached a significant level. The results of combining ability also showed that the variation among the combinations (Lucerne germplasm × Upland cotton) was mainly controlled by genes, and most traits had significant or extremely significant differences in parental GCA and combined SCA.
