樱桃番茄主要农艺性状与产量的相关及通径分析

对9个樱桃番茄品种的8个农艺性状进行了相关和通径分析.相关分析结果表明,单株产量与每穗结果数呈极显著正相关,相关系数为0.5967.回归分析和通径分析结果表明,每穗结果数和单果重对单林产量形成的直接作用最大,单株穗数对产量的间接作用大;这三个性状是影响单株产量的主要因素,可作为樱桃番茄丰产育种的主要选择性状.

Correlation and Path Analysis of the Main Agronomic Characteristic of Cherry Tomato

The correlation and path analysis of 8 agronomic characters were studied with9 varieties of cherry tomato. The results of correlation analysis showed that the yield and the fruit number of an inflorescence were positively eorrelated, r = 0. 5967 . The results on path analysis showed that the yield was affected mostly by the fruit number of an inflorescence andaverage fruit weight, and was indirectly affected by per plant inflorescence. Therefore, these three characters could be taken as selection characters for high yield.
