摘要/Abstract

摘要： 本研究选用矮变1号、冬协2号为主要矮源,通过株高的常规遗传分析、单体分析和赤霉酸(GA_3)鉴定,分析了矮源品种矮秆基因的遗传特点。结果表明:矮变1号受一对不完全显性矮杆基因控制,其株高和胚乳皆对 GA_3不敏感。蚰包的衍生系冬协2号、CA8333和农林10号的衍生系 G-230携带有相同的一对隐性矮秆基因 Rht2,且位于4D 染色体上,

关键词: 小麦矮秆基因,单体分析,赤霉酸敏感性

Abstract: Genetic studies by conventional method,monosomic analysis,and response togibberellic acid(GA_3)in the seedlings and endosperms were conducted for a prelimi-nary evaluation of several sources of dwarfness in common wheat crosses.The resultsshowed that Ai-bian 1 carried an incomplete dominant dwarfing

Key words: Wheat dwarfing gene, Monosomic analysis, Sensitivity of GA_3
