摘要: 在深绿叶的“地串”黄瓜品种单株自交后代群体中,分离出性状稳定的黄绿叶突变株系。遗传分析表明,突变株系的黄绿叶性状受一对隐性核基因控制。该性状在幼苗期表现,突变株能正常生存、繁殖,是一种可利用的形态标记。控制此性状的基因符号暂定名为yg1。
Abstract:A yellow green leaf character mutation in cucumber was isolated from a population of selfed individual plant of dark green leaf ‘De Chuan' cultivar.Genetic analysis showed that the yellow green leaf character was controlled by one pair of recessive nuclear genes.The character expressed at the seedling stage and the mutant plant have the ability to viable and propagate.It could be used as a morpholmarker.This yellow green leaf gene was provisionally designated as yg1.
