对辣椒10个农艺性状进行相关性和通径分析，估测了各性状之间的相关性及几个农艺性状对产量的相对重要性。试验结果表明，单株果数与单果质量呈显著负相关，果肉厚与果长、果宽呈显著正相关，株高、果宽、果肉厚、单果质量等性状都与产量呈显著正相关。通径分析表明，单株果数对产量的直接作用相当大，直接通径系数为0.9319，平均单瓜质量对产量的直接作用较大，直接通径系数为0.8421，因此，在辣椒育种中，应同时考虑单株结果数和单果质量2个性状。

We studied the correlation and path analysis of ten main agronomic characters of hot pepper, and estimated the relative importance of the main agronomic characters to total yield formation. The results showed that, fruit number per plant had a significant negative correlation with single fruit weight, and flesh thickness had a significant positive correlation with fruit length and width, while plant height, fruit width, flesh thickness, single fruit weight were related to the yield of hot pepper positively. The results of path analysis showed that, the yield was affected mostly by two agronomic characters, the fruit number per plant and average single fruit weight, and the direct path coefficient was 0.931 9 and 0.842 1 respectively, therefore, we should consider both fruit number per plant and average single fruit weight at the same time in the breeding of hot pepper.
