QTLs for effective silique number of main inflorescence on rapeseed (Brassica napus L.)
摘要
Abstract
Effective silique number on main inflorescence is an important factor on rapeseed (Brassica napus L. ) yield. Doubled haploids (DH) derived from ZY036 and 51070 were used to develop genetic markers on effective silique number. DH population was planted for 3 years at 4 locations as Wuhan -2010, Yangluo -2011, Qinghai -2011, Yangluo -2012 and Xiangyang -2012 respectively. In the 5 field trials, QTLs for the effective silique number on main inflorescence were identified using WinQTL Cartographer 2. 5 software. 10 QTLs were found. Their phenotypic variation,LOD value and additive effect ranged from 9.33% to 31.60% ,2.51 to 5.37 and 2.71 to 8. 09 respectively. Four QTLs on chromosomes A1 , A5, C1 and C9 were co - localized by 2 trials. In the QTL regions, 16 linkage markers were obtained, and 8 of 16 markers had less than lcM distance from the peak of the QTLs.关键词
