- Abstract
To explore the effects of morphological traits on the body weight of Cipangopaludina chinensis, 420 individuals from four locations (Dahua Yao Autonomous County, Hechi CityNandan County, Hechi CityQuanzhou County, Guilin CityXing’an County, Guilin City)were selected. A total of eight traits including body weight (Y), shell height (X1), shell width (X2), aperture height (X3), aperture width (X4), body whorl height (X5), the second spiral height (X6), the second spiral width (X7)were measured and analyzed using correlation analysis, path analysis, and multiple regression analysis. The results showed certain differences in the morphological traits and body weight of C. chinensis collected from the four locations. The coefficients of variation of body weight of C. chinensis in the four locations were all greater than 20%, indicating high breeding potential. Path analysis showed that the determinative coefficients of morphological traits on body weight were also different among the four locations. Four regression equations of morphological traits and body weight were established in four locations, Dahua Yao Autonomous County: YA=-16. 365+0. 682X1+0. 409X4+0. 162X7 (R² =0. 791)Nandan County: YB=-12. 233+ 0. 703X1+0. 177X2+0. 171X7 (R² =0. 807) Quanzhou County: YC=-17. 644+0. 763X1+0. 278X3+0. 160X4+ 0. 260X7 (R² =0. 890)Xing’an County: YD=-13. 538+0. 632X1 (R² =0. 945. Path analysis and multiple regression analysis jointly showed that shell height had a significant effect on the body weight of C. chinensis at all four collection locations. In summary, shell height and body weight are the major traits that should be referred to during the selection and breeding process of C. chinensis.
