THE RELATIONSHIP BETWEEN SHELL MORPHOLOGY AND BODY WEIGHT OF CYCLINA SINENSIS
青蛤(Cyclina sinensis)贝壳形态性状对软体部重的影响分析

A statistic study on the relationship between the phenotypic feature and the body weight was done on 245 samples of wild Cyclina sinensis collected randomly in China and Japan, using SPSS 13.0 package, in which the body weight was used as a dependent variable and other 6 morphological traits as independent variables, including shell height, shell length, shell width, ligament length, shell weight and total weight. The results show that only the coefficient between the body weight and the shell height is significant (P<0.01), the correlation index, path coefficients and determination coefficients are 0.953, 0.938 and 0.9080 respectively, indicating that the shell height is an important indicative trait for seed selection or breeding of C. sinensis.
