朝天椒主要农艺性状的相关性及通径分析

Correlation and Path Analyses on Major Agronomic Traits of Pod Pepper

为探讨朝天椒主要农艺性状的相关性及通径分析,以30个朝天椒为材料,采用完全随机区组设计方法,分析主要农艺性状与产量的相关性和通径系数。结果表明:单果鲜质量、果横径、单株挂果数与单株产量呈显著正相关,说明这3个性状是决定朝天椒产量的主要因素;通径分析表明,单果鲜质量、单株挂果数、果横径对朝天椒鲜果产量有直接正向效应。因此,在朝天椒新品种选育过程中,重点考虑上述几个性状,并协调好各性状间的关系,以提高朝天椒产量。

To explore the relationships among major agronomic traits of pod pepper, thirty cultivars were selected as the materials. Their traits were measured based on completely randomized block design experiments. Relationships between the traits were investigated using correlation and path analyses. Significantly positive correlated relationships were observed among yield, fruit single fresh weight, fruit diameter, and fruit number per plant, which indicated that these traits were the major factors affecting yield. Path analysis indicated that fruit single fresh weight, fruit number per plant, fruit diameter had directly positive contribution to yield. Therefore, when breeding new pod pepper varieties,we should pay more attention to these traits and coordinate their relationships to increase the yield of pod pepper.
