title: Genetic mapping and QTL analysis of growth traits in the large yellow croaker Larimichthys crocea.
abstract: Large yellow croaker (Larimichthys crocea) is an important maricultured species in China. A genetic linkage map of the large yellow croaker was constructed using type II microsatellites and expressed sequence tag (EST)-derived microsatellites in two half-sib families (two females and one male). A total of 289 microsatellite markers (contained 93 EST-SSRs) were integrated into 24 linkage groups, which agreed with the haploid chromosome number. The map spanned a length of 1,430.8 cm with an average interval of 5.4 cm, covering 83.9 % of the estimated genome size (1,704.8 cm). A total of seven quantitative trait locis (QTLs) were detected for growth traits on five linkage groups, including two 1 % and five 5 % chromosome-wide significant QTLs, and explained from 2.33 to 5.31 % of the trait variation. The identified QTLs can be applied in marker-assisted selection programs to improve the growth traits.
