QTL Mapping and Analysis on Bolting and Flowering Time in Cabbage

doi:10.7668/hbnxb.2013.05.001

Abstract

Abstract: Based on the Cabbage genetic linkage map which had been constructed previously, QTL mapping and analysis related to bolting and flowering time in the individuals of F₂ were conducted using MapQTL 4.0.Two QTL(qbt-3-2,qbt-9-1)located on LG3 and LG9 controlling the traits of bolting time and one QTL(qft-9-1)located on LG9 controlling the traits of flowering time in cabbage were detected. The three QTLs are all the sites of additive effect,17.5%,22.7%of variation that can be explained respectively. Meanwhile,two molecular markers(E46M52-5,me26-em13-1)corresponding with the QTLs could be used for M-AS of breeding for bolting tolerance. It will pro-vide the basis of theoretical for the resistant bolting varieties breeding.
