Study On The Reproductive Fertility Of The First Filial Generation Of Wild Japanese Quails And Domestic Quails

After catching 40 wild Japanese quails(9♂,31♀) from which migrated to and settled down Weishan Lake region, and 37 domestic quails(10♂,27♀)from quail breeding farm in Yangzhou City, Jiangsu Province, normal and reciprocal cross was carried out. The reproductive behaviours of the first filial generation of wild Japanese quails and domestic quails were compared with their parental combination. Meanwhile, microtomy was used in observing the genital system of the F1. With all the messages taken into account, such conclusions could be drawn as follows:1. In cross combination of female wild Japanese quails and male domestic quails, fecundity as well as the viability of the F1 was lower than those of reciprocal crossing. It may be that wild female quails had much stronger psychological isolation option. Meanwhile, seasonal reproduction, a kind of biological habits, put gentle influence on hybrid fertility through female quails. And it is possible that be one of prezygotic isolation mechanisms about the population evolution divergence.2. There was no significant difference in tweet and mating between wild Japanese quails and domestic quails(P>0.05). Reproductive performances of the first filial generation were in the middle of the domestic quails and the wild Japanese quails, though there were significant different from the wild Japanese quails in mating(P<0.05),and significant different from the domestic quails in fighting and tweet(P<0.05). The F1...
