Abstract: The laying performance， hatching performance and egg quality of Yandang native chicken parental generation of two lines were measured in a 365 day experiment. The reproductive performance was also analyzed in this paper. The result was that，forⅠline， the annual egg yield was 220， the average egg weight was 4642 g， the egg shape index was 129， the average egg laying rate in a laying year was 6027%， the egg fertilization rate was 923%， the hatching rate of fertilized egg was 932%. For Ⅱ line， the annual egg yield was 217， the average egg weight was 4532 g， the egg shape index was 125， the average egg laying rate in a laying year was 5945%， the egg fertilization rate was 916%， the hatching rate of fertilized egg was 919%. Reproductive performance difference between the two lines was not significant. Compared with other species， the laying performance of
Yandang native chicken was significantly lower than that of specialized lines， but slightly higher than that of Lingkun chicken and Xianju chicken， which belong to the similar type of species. And the egg quality and hatching performance were all at a high level.

Key words: Yandang native chicken, parental generation, reproductive performance
