| 摘 要： | 对20份苦瓜材料的12个性状进行相关及通径分析。相关分析结果表明,苦瓜产量与前期果数呈显著正相关(r=0.52074),与其他性状差异均为不显著。通径分析结果表明,对苦瓜产量形成所起的直接作用较大的3个性状是单瓜重、瓜形指数、瓜长,直接通径系数分别为1.46221、1.30622、-1.07396。

| Abstract: | Correlation and path analysis of 12 agronomic traits of 20 balsam pear materials were studied. The results correlation analysis revealed that significant positive correlation (r=0.52074) was found between the yield and the number of fruit,while insignificant correlations were found between the yield and other traits. The result of path analysis showed that the yield was affected by three agronomic traits: average fruit weight,fruit shape index and fruit length.,and the direct path coefficients were 1.46221,1.30622,and -1.07396 respectively. |
