QTL Mapping for Seedcoat Color in Chinese Cabbage ( Brassica rapa L.ssp.pekinensis )
摘要
Abstract
183 doubled haploid( DH ) lines derived from the cross of two Chinese cabbage ( Brassica rapa L. ssp. Pekinensis) DH lines, Y177-12 ( brown seed)and Y195-93( yellow seed) ,were used to map'quantitative trait loci (QTL) related to seedcoat color. Seedcoat color was measured by ocular estimation and colorimeter with CR-400 ( KONICA MINOLTA). Based on the reported genetic map with 457 loci, nine quantitative trait loci ( QTLs ) were detected for seedcoat color,localizing on linkage groups A4 , R6 , A7 and RIO , respectively. The most significant of the identified QTLs locates on A6,named Sc-1, colocalized with ScL-2 and Scb-2, explaining 80.4% - 100 % of the phenotypic variance.关键词
