Abstract: The breeding of Jianghan chicken A strain was studied for 4 generations by modern breeding methods for whole family and MAS,with Jianghan chicken as the basic breeding material,high-yield genes were introduced.The results showed that the feather characteristics of Jianghan chicken A strain were basically stable,with 100% of may-feather chicken.For the core group of generation 4,the age of 50% of egg production was 7 d in advance;Body weight at age of 300 days was improved by 139.10 g and 90.81 g for cock and hen,respectively;The average egg weight of generation 0 was 51.26 g,and that of generation 4 was 50.28 g.The egg production number of generation 4 was 104.35,increased by 9 compared with generation 0;The proportion of green-shell eggs in the observation groups of generation 3~4 was over 99%,and it was 100% in core groups for generation 0~4.The proportion of green-shell eggs can be precisely controlled by MAS in commercial stocks.

Key words: Jianghan chicken, strain breeding, egg production, Marker assisted selection(MAS), green shell gene
