Genetic linkage map of Brassica campestris L. using AFLP and RAPD markers

摘要

A genetic linkage map comprised of 131 loci was constructed with an F_2 population derived from an inter-subspecific cross between Brassica campestris L. ssp. chinensis cv. 'aijiaohuang' and ssp. rapifera cv. ' qisihai' . The genetic map included 93 RAPD loci, 36 AFLP loci and 2 morphological loci organized into 10 main linkage groups (LGs) and 2 small groups, covering 1810. 9cM with average distance between adjacent markers being approximately 13.8cM. The map is suitable for identification of molecular markers linked to important agronomic traits, QTL analysis, and even for marker-assisted selection in breeding programs of Chinese cabbage and turnip.
