摘　　要：为提高蛋鸭配套系F(PS)的麻羽率,利用山麻鸭(S)分别与闽农白羽蛋鸭(F)和莆田黑鸭(P)进行正反交试验,观测各杂交组合后代雏鸭的羽色表现和分离情况,选择杂交后代麻羽率高的亲本个体进行纯繁、继代选育。结果显示:经过3个世代的选育,F×S和S×F组合雏鸭麻羽率取得显著进展,分别从44.0%和41.7%提高到84.3%和81.9%;P×S与S×P组合雏鸭麻羽率分别从19.2%和10.6%提高到22.8%和32.7%,也取得一定进展。同时,还分离到1个新品系"莆田麻鸭",有利于加快麻羽率选育。由此表明,本研究采用的正反交技术路线可行,可以有效提高蛋鸭配套系F(PS)的麻羽率。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.Results showed 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）.
