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 R10, 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.

Key words: Chinese cabbage, Seedcoat color, QTL mapping
