Liao juan;Wang Gang;Yu Shigang;Leshan Normal University,Engineering Research Center of Sichuan Province Higher School of Local Chicken Breeds Industrialization in Southern Sichuan;  
The body weight and body size of the 90-days-old yellow miscellaneous chicken were measured and analyzed to study the relatioships of each trait. The results showed that the weight,chest depth,chest width,sternum length,tibial length,tibial circumference and back width of cocks were significantly higher than those of hens(P0.01),and there was significant positive correlation among these traits(P0.01). In all the correlation coefficients,the correlation coefficient of body weight and chest width was the largest(r=0.809),the correlation coefficient of chest depth and tibial circumference was the smallest(r=0.363). This experiment indicated that chest width could as a breeding index to improve the chicken′s weight.
