作者朱国华等选用矮变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秆基因控制,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Rh t2,且位于4D染色体上,其株高对GA_3不敏感,
The author Zhu Guohua and other selected dwarf No. 1, No. 2 Winter Association as the main dwarf source, through conventional genetic analysis of plant height, monomer analysis and gibberellic acid (GA_3) identification, analysis of the dwarf varieties of dwarf gene genetic characteristics. The results showed that: Dwarf 1 was controlled by a pair of imperfect dwarf genes, and its plant height and endosperm were insensitive to GA 3. The derivative lines of Douchi No.1, No.2, CA8333 and G- 230 carries the same pair of recessive dwarfing genes Rh t2, located on chromosome 4D, whose plant height is insensitive to GA 3,
