Technical Abstract: As part of our scan of the porcine genome aimed at identifying quantitative trait loci (QTL) of economic importance in marker-assisted selective breeding programs, we examined 8 growth, 12 carcass and 8 reproductive traits in a three generation reference family. The descendants of 3 Meishan boars and 7 Yorkshire sows from 25 full and half-sib families (304 individuals) were genotyped with microsatellite markers spaced at ~ 20 cM on chromosomes 1, 2, 4, 5, 6, 7, 8 and 13. F-ratios supporting QTL location were calculated using the least squares regression method program developed by Knott and Haley, Roslin Institute. Results sufficiently interesting for immediate follow-up were observed for birth weight and number of corpora lutea and suggestive results were obtained for other loci
