Quantitative trait loci analysis of egg and meat production traits in a red junglefowl x White Leghorn cross

Wright D, Kerje S, Lundstrom K, Babol J, Schutz K, Jensen P, Andersson L


Egg and production traits are of considerable economic importance in chickens. Using a White Leghorn x red junglefowl F-2 intercross, standard production measures of liver weight and colour, egg size, eggshell thickness, egg taste and meat quality were taken. A total of 160 markers covering 29 autosomes and the Z chromosome were genotyped on 175-243 individuals, depending on the trait under consideration. A total of nine significant quantitative trait loci (QTL) and three suggestive QTL were found on chicken chromosomes 1, 2, 4, 5, 7, 8, 10, 12, E47W24 and E22C19W28
