摘要: 为探究中国圆田螺(Cipangopaludina chinensis)各形态性状间的相关性及对体质量的影响,采集广西壮族自治区4个地点(河池市大化瑶族自治县、河池市南丹县、桂林市全州县、桂林市兴安县)的中国圆田螺420只,测量体质量(Y)和壳高(X1)、壳宽(X2)、壳口高(X3)、壳口宽(X4)、体螺层高(X5)、第二螺层高(X6)、第二螺层宽(X7),进行相关性分析、通径分析和多元回归分析。结果表明,4个地点所采集的中国圆田螺形态性状与体质量均存在一定的差异,其体质量变异系数均大于20%,具有较高的选育潜力;通径分析表明,不同采集点的中国圆田螺形态性状对体质量的决定系数也不同。建立4个采集点中国圆田螺形态性状与体质量的回归方程,大化瑶族自治县:YA= -16.365+0.682X1+0.409X4+0.162X7R2=0.791);南丹县:YB= -12.233+0.703X1+0.177X2+0.171X7R2=0.807);全州县:YC= -17.644+0.763X1+0.278X3+0.160X4+0.260X7R2=0.890);兴安县:YD= -13.538+0.632X1R2=0.945)。通径分析和多元回归分析共同表明,壳高对4个采集点中国圆田螺的体质量都产生了显著性影响。综上所述,在中国圆田螺良种选育的过程中,壳高和体质量是重点参考的指标。

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 City;Nandan County,Hechi City;Quanzhou County,Guilin City;Xing’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);QuanzhouCounty: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.
