| 摘 要： | 【目的】分析黄瓜雌性遗传效应，为黄瓜雌性系和新品种选育提供理论依据。【方法】以雌性系（D0401、D0420）、强雄性系（D06103、D0819）、普通的雌雄异花同株（HL-3）黄瓜为试材，按照Griffing 双列杂交试验方法Ⅳ1/2P(P-1)配制杂交组合，同时选取其中一个组合（D0420×D06103）构建6世代群体P1、P2、F1、F2、B1、B2，调查统计单株25节内的雌花节率，采用数量性状A-D遗传模型，分析不同季节（春季、秋季）黄瓜雌性遗传规律。【结果】黄瓜的雌性遗传符合A-D遗传模型。加性方差、显性与环境互作方差占总变异的比率分别为51.05%、19.66%，显性和加性与环境互作效应均为0；狭义遗传力、广义遗传力均为51.05%；环境互作狭义遗传力为0，环境互作广义遗传力为19.65%。【结论】黄瓜全雌性是多基因控制的数量性状；雌花节率主要是由基因加性效应所控制，常规杂交育种早期世代选择有效；环境（季节）对雌花节率影响较大。

| Abstract: | 【Objective】 The objective of this experiment was to analyze the genetic effects of gynoecious in cucumber in order to provide a theoretical basis of gynoecious and new varieties breeding. 【Method】 Gynoecious (D0401, D0420), subandroecious (D06103, D0819) and monoecious (HL-3) were used as test materials using Griffing Ⅳ1/2P (P-1) to build a hybrid combination. One was selected (D0420×D06103) to construct 6 generation groups, such as P1, P2, F1, F2, B1, B2. According to the investigations and statistics of the proportion of female flowers of individual plants within 25 knots, quantitative traits additive-dominant (A-D) models were used to analyze the female genetic regularity of cucumber in different seasons (spring, autumn), such as P1, P2, F1, F2, B1, B2. 【Result】The gynoecious in cucumber genetic consistent with the A-D genetic model. The addition variance and dominant-environmental variance were 51.05% and 19.66%, respectively. The dominant variance and addition-environmental variance were 0, narrow heritability, broad heritability was 51.05%, environmental-narrow heritability was 0, and the environmental-broad heritability was 19.65%. 【Conclusion】The gynoecious in cucumber is mainly a quantitative trait controlled by multiple genes; the proportion of female flowers is controlled by additive effect and conventional crossing breeding can be selected during the earlier generations. The environment (season) has a main effect on proportion of female flowers in cucumber. |
