黄瓜的早熟性状主要表现在第一雌花节位、节成性和前期产量等方面。要获得一代杂种早熟的优势必须选择配合力良好的亲本。亲本早熟性状配合力的高低是杂种优势利用成败的关键,因而探讨黄瓜早熟性状的遗传效应对确定杂种优势具有十分重要的意义。本文仅就黄瓜第一雌花节位、节成性与前期产量的相关性,第一雌花节位的遗传力和 Cucumber prematurity traits mainly in the first female flower node, the festival of pre-and early yield and so on. To get the first generation of hybrids precocious advantages must choose a good parent. Therefore, it is of great importance to study the genetic effect of prematurity in cucumber to determine the heterosis. In this paper, only the first female flower section of cucumber, section of the early yield and sex, the first female flower node heritability and
