摘　　要：为寻求能广泛用于不同遗传背景下高油品种选育的含油量筛选的分子标记,利用前人研究结果,开发了油菜含油量KASP分子标记,进行了KASP分子标记筛选试验。结果表明:通过F2群体验证,该标记与A05染色体上含油量QTL紧密连锁,这将助力于在长江中游地区定向选育高含油量“丰(沣)油”系列油菜品种。To identify the molecular markers that can be widely used in the breeding of Brassica napus cultivars with high seed oil content under different genetic backgrounds,we developed a Kompetitive Allele-Specific PCR(KASP)marker for seed oil content on the basis of the available research results.The verification with the F2 population suggested that the marker was closely linked to the quantitative trait locus conferring seed oil content on chromosome A05.The findings are conducive to the directed breeding of'Fengyou'cultivars with high seed oil content in the middle reaches of the Yangtze River.
