丝瓜主要早熟性状的分析研究

Preliminary Studies on Early Maturity Characters in Luffa

通过遗传相关分析、通径分析、主成份分析对丝瓜 7个早熟性状进行研究。结果表明 :座果率、商品瓜的日增克数为最重要性状 ,其次为单株叶片数的增长速度、单株雌花数、单瓜重。第一雌花节位与丝瓜早熟性也有一定关系。

Through analysis of correlation of coefficient,path coefficient and principal component,the early maturity of luffa was studied.The results showed that the increased fruit weight per day and the fruiting rate were the most important characters.The next important characters were the increasing rate of single plant leaf number,single plant female flower number and single fruit weight.The place of the first female flower was also related with the early maturity of the luffa.
