Glucosinolates, anticancer active substances, are widely present in Brassica crops.It will be of important significance to carry out the breeding of high content of Glucosinolates new varieties of cabbage.This study analyzed total glucosinolate content of F2 mapping population parents and that of 83 individual plants by HPLC methods.Based on the cabbage high-density genetic linkage map which had been constructed previously, QTL mapping and analysis related to Glucosinolates total content in the individuals of F2 were performed using MapQTL 4.0.Three QTLs(qGS-7-1, qGS-8-1, qGS-8-2) located on LG7 and LG8 controlling the traits of Glucosinolates total content in cabbage were detected.The contribution rate were 13.6%, 7.5% and 5.6%, respectively.Meanwhile, two molecular markers(me27-em25-2, E38M55-7) coseparating with the QTLs could be useful for marker assisted selection of cabbage breeding rich in Glucosinolates.
