大豆主要产量性状QTL定位分析
A QTL mapping analysis of main yield traits in soybean
摘要
Abstract
[Objective]This study explored closely linked and stable marker loci of soybean yield traits , giving a theoretical basis for cultivating high yield soybean varieties by marker -assisted selection .[Method]QTL mapping and effects of four major yield-related traits were analyzed using QTL IciMapping v 2.2 com-plete interval mapping method for two years in soybean F 2 and its derived populations .[Result and conclu-sion]The results showed that the LOD =2.5 was the threshold , and nineteen obvious additive effect QTLs were detected in the number of soybean seeds per plant , seeds mass per plant , 100 seeds mass and number of pods per planting four major production traits , including 15 main effect QTLs , namely , the number of seeds per plant QTLs 3, the number of pods per plant QTLs 2, seeds mass per plant QTLs 10, which were located at 4 (C2), 12 (G), 6 (A1) and 17 (M) 4 linkage groups.In addition, three stable QTLs were located in two years , namely, the number of seeds per plant QTL qNSPP-12-1, seeds mass per plant QTLs qSWPP-12-1 and qSWPP-12-2.One new QTL of seeds mass per plant was preliminarily located , namely, qSWPP-12-5.The stable existence and main effect QTLs which were detected in this study will give impor-tant guiding significance for soybean genetics and breeding in the future research .关键词
