Studies on Reproductive Character of Mule Duck

摘要: 从北京鸭(♂)×番鸭(♀)属间杂种F1代大群中选出两只有性行为的雄性半番鸭和7只生殖器官有不同发育的雌性半番鸭。对该F1代的解剖学、组织学及杂交试验显示:属间杂交鸭并非完全不育;雌性半番鸭卵巢发育不全是造成产蛋能力低的直接原因;番鸭和家鸭的第1号染色体和Z染色体核型不同是造成F1不育的主要原因。Abstract: Two male mule ducks with sexual behavior and seven female ducks with different development reproductive organ were selected from a herd of F1 ducks crossbred from Beijing duck (♂) and Muscovy duck (♀).The experiments of anatomy, histology and cross showed that intergeneric hybrid duck didn’t lose their fertility completely; The agenesis of F1 duck ovary was the direct reason for the low reproductivity; The different karyotype in Pair 1 and Z chromosome of Muscovy duck and Beijing duck was the major reason for infertility in their F1 progenies.
