Abstract

Abstract

To improve black-speckle feather ratio of synthetic line F(PS),Shanma duck(S) was cross-breeded reciprocally with Minnong white duck(F) and Putian black duck(P),respectively.Feather color appearance and segregation ratio of the hybrid progeny were observed.The purebred parents whose hybrid progeny displayed high black-speckle feather ratio were selected at each generation.Resultsshowed that after three generations breeding,there were significant improvement in black-speckle feather ratio of F×S and S×F combination,increasing respectively from 44.0% and 41.7% to 84.3% and 81.9%.Black-speckle feather ratio of P×S and S×P combination were increased from 19.2% and 10.6% to 22.8% and 32.7%,respectively.Moreover,a new strain Putian black-speckle duck was isolated,which would speed up breeding process on black-speckle feather ratio.The reciprocal cross in this study effectively improved black-speckle feather ratio of synthetic line F(PS).
