Quantitative trait loci mapping of fatty acid based on soybean backcross introgression lines
摘要
Abstract
For molecular marker assistant breeding on higher soybean fatty acid,quantitative trait loci(QTL) mapping of predominant fatty acid components in seeds were carried on 100 BC2 lines of backcross introgression lines from Zhonghuang 13 and Dongshan 69. Gas chromatography was used to determine fatty acid components. Re-sults included a linkage map constructed with 130 polymorphism SSR markers. The total distance of the map was 2 433. 29 cM containing 19 linkage groups,and the average distance between markers was 18. 86 cM. Total 47 QTLs related to 5 fatty acid components were detected,and 21 of them were repeatable QTLs. QTL qFA - C2 - 4, qFA - J - 1,qFA - D1b - 1 and qFA - O - 1 appeared consistently over the 3 year period. Among them,qFA - C2- 4 was mapped for linolenic,qSA - J - 1 and qFA - D1b - 1 were for stearic,qFA - O - 1 were for both oleic and linolenic. QTL qFA - D1a - 1 and qFA - C2 - 4 were novel QTLs for several fatty acids. QTL qFA - C2 - 3,qFA- J - 1,qFA - D1b - 1 and qFA - O - 1 were newly reported.关键词
