The eggs of 35-week-age Gushi chicken were selected to investigate the egg quality traits of 5 different varieties. The results showed that：（1）The excellent egg quality traits of hardness and eggshell thickness（54.67~58.60μm）, florid yolk (8.56~9.17) and low content of yolk cholesterol （221.11~233.94mg/egg） remained in every variety; but there were some drawbacks, such as low egg weight（48.13~50.51g）and egg shape index（1.21~1.30）in some varieties. (2)The result of correlation analysis of every egg trait showed that it had difference in different varieties, such as cholesterol：between cholesterol and egg weight there was significantly positive correlation (p<0.05) (r=0.79878~0.80938)both in Yellow feather Gushi Chicken with black skin and piebald feather Gushi Chicken, and between cholesterol and content of egg white crude protein the correlation was significantly positive (p<0.01) (r=0.88288)in piebald feather Gushi Chicken; meanwhile，there was negativesignificantly correlation (p<0.01) between cholesterol and weight of egg shell (white feather Gushi Chicken with white skin, r= -0.98537)and cholesterol and yolk crude protein(yellow feather Gushi Chicken with black skin, r= -0.9225).
