对豇豆热性的两个主要构成性状（开花前天数和第一花序节位）进行遗传分析的结果表明，早熟品种作母本时F_1代表现为早熟超亲，晚熟品种作母本时F_1代为中间偏早的不完全显性，母本影响较大。在FF_2代，开花前天数是单峰状曲线连续分布，第一花序节位呈多峰状曲线连续分布。开花前天数比第一花序节往的遗传力和遗传进度大、遗传变异系数小，对微笑始收前天数的通径系数高，因而对熟性影响较大，故在品种连育过程中要给予重视。
The results of genetic analysis of the two main constitutional characteristics of cowpea (pre-flowering days and first inflorescence node) showed that the F_1 generation of early-maturing cultivars was premature, In the middle is not completely dominant, female parent greater impact. In FF_2 generation, the number of days before flowering was a continuous distribution of unimodal curves, and the first inflorescence node was continuously distributed with multimodal curves. Before flowering days than the first inflorescences to go heritability and genetic progress, genetic coefficient of variation is small, before the beginning of the smile before the harvest of the number of days of the high path coefficient, and thus a greater impact on the maturity, so the variety of breeding process Give attention.
