摘要
对22个朝天椒种质材料主要株型性状与产量的相关和通径分析结果表明:主要株型性状与产量相关性强弱为单果重>冠高>结果层数>茎粗>始花节高>有效侧枝数>第一分枝夹角>单株结果数>冠幅>株高>冠干比。其中,单果重和冠高与产量呈极显著和显著正相关,说明单果重和冠高的增加有利于朝天椒产量的提高。在朝天椒品种的选育以及栽培过程中,应在保证结果层多的前提下,着重提高单果重和单株结果数,并协调好它们之间的关系。
The correlation and path of main agronomic characters and yield of 22 pod pepper varieties were analyzed.The results showed that the main agronomic characters affecting yield were single fruit weightcrown heightfruit-bearing layersstem diameterheight of node for first flowerNo.of effective lateral branchesangle of the first branchfruits per plantcrown diameterplant heightratio of crown to stem,and there was a very significant positive correlation between single fruit weight and yield,and a significant positive correlation between crown height and yield,which indicated that single fruit weight and crown height were main factors affecting yield,and the single fruit weight and fruits per plant characters and coordination between single weight and fruits per plant with the prerequisite of more fruit-bearing layers should be paid more attention to in breeding and cultivation of pod pepper.
