利用６个甘蓝晚熟热本自交系，按双列杂交法配制３０个组合进行主要数量性状配合力和遗传分析。结果表明，甘蓝帮叶比、紧实度、中心柱长、病毒病、黑腐病５个性状在各亲本系间的配合力有差异，亲本系之间选择有差异，并在一代杂种中能配最佳组合；紧实度、病毒病、黑腐病３性状以广义遗传力为主，杂种优势利用是育种的重要途径；中心柱长、帮叶比二性状以狭义遗传力为主，着重一般配合力的选择，系统选择双亲，可获较好杂种。 Using six cabbage late-maturing heat-inbred lines, 30 combinations were prepared by double-row hybridization to analyze the combining ability of major quantitative traits and genetic analysis. The results showed that there were differences in the combining ability of five traits including cabbage leaf ratio, compaction degree, central column length, viral disease and black rot with each parental line. With the best combination; firmness, virus disease, black rot 3 traits with broad heritability, the utilization of heterosis is an important way of breeding; central column length, leaf to leaf than the traits with narrow heritability mainly focus on The choice of general co-operation, the system of choice of parents, can get better hybrids.
