黄瓜雌性系,是只开雌花不开或少开雄花,具有早熟、抗病、瓜多果密、收获集中利於黄瓜杂种一代简化制种需要的新类型。经1976—1978年研究分析:黄瓜雌性系性型分类具有四种型式,即全雌型、多雌型、普通型及少雌型。通过各类性型的杂交、回交与自交后代分离情况,初步总结出黄瓜雌性系性型遗传规律:为一对核等位基因控制的简单遗传、杂交一代雌性为显性,回交时分离的雌雄比例为1∶1,自交分离比例近於3∶1,具有隐性基因的少雌型自交分离时性型稳定。此外,本文还总结了黄瓜雌性系人工诱雄制种的有效药剂,浓度、处理时期、节位及其方法。
Cucumber female line, is only open female flower is not open or less open male flowers, with early maturity, disease resistance, melon and more fruit dense, concentrated in favor of the cucumber hybrid generation to simplify the production of new types of seed. The 1976-1978 research analysis: cucumber female lineage type has four types, namely, all female, multi-female, common and less female. Through the segregation of various types of hybrids, backcrosses and selfing offspring, we initially summarized the genetic rule of the female lineage in cucumber: a simple inheritance controlled by a pair of nuclear alleles, The ratio of male to female was 1: 1, the rate of selfing was close to 3: 1, while the female with recessive gene was stable in selfing. In addition, this article also summarizes the effective agent, concentration, treatment period, node and its method of cucumber female artificial lure seed production.
