朝天椒种质资源主要农艺性状的相关性分析

Correlation Analysis on Main Agronomic Characters of Pod Pepper Germplasm Resources

对50份朝天椒种质资源主要农艺性状进行了相关性分析,结果表明,所考察的性状中仅首花节位和株高与单株产量均呈极显著和显著负相关关系,而果肉厚、果实横径、果实纵径、单果重、心室数、单株果数与单株产量呈极显著正相关关系,说明这6个性状是决定朝天椒单株产量的主要因素。因此,在朝天椒新品种选育过程中,重点考虑这几个性状,并协调好各性状间的关系,以提高朝天椒产量。

The main agronomic characters of pod pepper germplasm resources were researched by correlation analysis. The correlation analysis showed that only number of leaves below the first flower and plant height had very significant and significant negative correlation with yield of per plant, but there were very significant positive correlation among thickness of flesh, transverse diameter of fruit, longitudinal diameter of fruit, weight per fruit, number of locules, number of fruits per plant and yield of per plant. And these 6 characters were main factors affecting yield. So when breeding new pod pepper varieties, we should pay more attention to these characters and coordinate their relationship to in- crease production of pod pepper.
