摘要
种皮色泽和花青甙显色是绿豆(Vignaradiata)的重要性状,可在纯度鉴定、辅助选择育种等研究中发挥作用。本研究以绿豆核心种质种皮色泽、花青甙显色性状分析为基础,配制杂交组合,根据不同世代的表型调查,探讨绿豆种皮颜色、光泽和花青甙显色等性状的遗传特征。结果表明,绿种皮对黄种皮为单基因控制,绿色为显性;黑种皮对绿种皮为单基因控制,黑色为显性。绿豆种皮光泽不符合简单性状的遗传规律,且不同组合间后代的表型分布存在差异。绿豆种皮色与光泽间无连锁关系。植株各部位的花青甙显色对不显色为显性,均符合简单单基因的分离特点。进一步分析表明,不同部位花青甙显色的相关性不一致,其中控制幼茎色与复叶基部花青甙显色的基因紧密连锁在一起,或为一个基因,而控制龙骨瓣花青甙显色的基因与其他相关基因的遗传连锁程度最低。本文对绿豆种皮相关性状及植株花青甙显色性状的遗传分析将为这些性状的育种利用及深入研究奠定基础。
Seed coat color and anthocyanidin coloration are important traits for variety identification and marker assisted selection in mungbean. Based on the phenotypes of progenies from different combinations, we analyzed the inheritance of the traits above. The results showed that seed coat color was controlled by mono-gene, and green was dominant to yellow, while black was domi- nant to green. The seed luster had a complicated genetic model, and there was no relationship between seed coat color and luster. The inheritance of anthocyanidin coloration on different parts of plant was also agreeable to mono-gene. However, the relation- ships among anthocyanidin coloration on different parts of plant were not similar. The genes controlling anthocyanidin coloration in seedlings and in leaf base might be tightly linked together or be the same, while the gene controlling anthocyanidin coloration in keel was not linked with other genes.
