摘　　要：利用RI群体,对西瓜的8个果实性状进行统计分析,探索西瓜主要果实性状与裂果性状的相关关系。方差分析结果显示8个性状间差异显著。相关分析结果表明果实裂应度与其他性状的相关关系都不显著,果实横径、外果皮绿皮层厚度、中心可溶性固形物含量、边部可溶性固形物含量与果实裂应度呈正相关关系,果实纵径、果形指数、果皮厚度与果实裂应度呈负相关关系。通径分析得出果形指数对果实裂应度的直接效应最大,决定系数为0.10241,剩余通径系数为0.94741,说明试验中所调查的7个性状对果实裂应度的相对决定程度较小。The correlation between watermelon fruit split rate and main fruit traits was investigated by statistical analysis of 8 fruit traits in the RI group. The results of variance analysis showed a significant difference of the traits measured. The results of correlation analysis showed that there is no significant correlation between fruit split rate and the other fruit traits. There is a positive correlation between fruit diameter, the green layer thickness of exocarp, content of fruit center sugar, content of fruit out edge sugar and fruit split;and a negative correlation between fruit length, fruit shape index,pericarp thickness and fruit split rate. The path analysis showed that direct effect to fruit split is fruit shape index by and the decision coefficient is 0.102 41, the residual path coefficient is 0.947 41, suggesting that 7 other fruit traits surveyed have lesser relative decision extent.
