Abstract: Crucian carp Carassius auratus is rich in genetic diversity, and becomes a good candidate for research of molecular markers or genes associated with those growth traits. In the current study, 79 SSR and 22 EST-SSR markers were chosen to analysis the genom- ic of 181 progenies from a crucian carp F2 family. A GLM （General Linear Model） procedure was used to analyze the correlation be- tween markers and four growth traits including body weight, body length, body depth and body width. The significance testing by Per- mutation test（ 10 000 replicates）, 22 makers were shown to fit the correlation from four growth traits （P〈0.05）, very significant corre- lation （P〈0.01） for HLJYJ15 and HLYJ244. Markers and gene types related to the four growth traits were obtained from this research, which gives effective basis to the study of crucian carp marker-assisted breeding and genetic mechanism of growth traits.

Key words: Carassius auratus, SSR, EST-SSR, body weight, standard length, body depth, body width
