对28个辣(甜)椒品种的13个主要早熟性状的遗传参数进行分析。结果表明,单株早期产量、早总比性状的遗传力较低;始花节位,现蕾期、开花期、早期果重的遗传力高,并与单株早期产量、早总比、单株早期采果数呈显著或极显著遗传相关,且对这3个性状进行间接选择的相关遗传进度较高;开花期对始花节位,现蕾期进行间接选择的效果极佳。因而,以开花期、早期果重作为直线选择性状,可简便地间接选择单株早期产量、早总比等早熟经济性状。
The genetic parameters of 13 major precocious traits in 28 spicy (sweet) pepper cultivars were analyzed. The results showed that the heritability of early yield per plant was lower than that of traits. The heritability of early flowering node, budding stage, flowering stage and early fruit weight was high, The number of early fruit picking was significantly or extremely significant genetic correlation, and the genetic traits of indirect selection of these three traits were high. The effect of indirect selection of flowering stage and budding stage at flowering stage was excellent. Thus, at the flowering stage, early fruit weight as a linear selection trait, can be easily indirect selection of early yield per plant, early ratio than other precocious economic traits.
