加工番茄主要农艺性状与产量的相关及通径分析

对加工番茄11个杂交组合的主要农艺性状进行相关及通径分析,估测加工番茄12个主要性状对单株产量形成影响的相对重要性,结果表明,单株产量与单果质量、干物质含量相关关系达极显著水平,相关系数分别为0.9045和-0.7627;单株产量与果形指数、前期产量呈显著正相关。农艺性状对产量的通径分析结果表明,单果质量与干物质是影响单株产量的主要因素,在加工番茄丰产育种中可作为主要选择性状。

Correlation and Path Analysis of the Main Agronomic Characters and Yield of Processing Tomato

Eleven crossing combinations of processing tomato were used for conducting the correlation and path analysis oftwelve main characters which form the yield of processing tomato. The results showed that the yield per plant had very significant relationship with fruit weight and dry matter content, the correlation coefficients were 0.9045 and -0.7627, respectively. The yield per plant had significant positive relationship with fruit shape index and early yield. The path analysis was made of agronomic characters to the output, the results showed that fruit weight and dry matter content were main factors which directly influenced the yield per plant of processing tomato and can be major characters for breeding new processing tomato cultivars with high yield.
