| 摘 要： | 对21份紫圆茄果实的主要性状和果脐面积进行了相关和通径分析。相关分析结果表明:果型指数和果脐面积呈显著负相关,果肉颜色与果脐面积呈显著正相关,相关系数分别为-0.463和0.446。通径分析结果表明:横径对果脐面积的正向直接作用最大,单果质量对果脐面积的负向直接作用最大,纵径通过果脐指数对果脐面积有着较大的正向间接作用,果肉颜色对果脐面积的直接作用最小。

| Abstract: | The correlation and path analysis of 5 main fruit agronomic characters and hilum size in 21 eggplant cultivars and lines were studied.The results of correlation analysis showed that the fruit shape index had a significant negative correlation with hilum size,but the flesh color had a significant positive correlation with it,and the correlation coefficients was-0.463 and 0.446 respec-tively.The results of path analysis showed that the fruit width had the biggest positive and direct effect on hilum size,but s... |
