“矮变1号”小麦是西安市农科所从“矮秆早”中选出的天然突变系。已被国内一些育种单位作为矮源利用,其矮秆遗传特性国内外亦作了一些研究。1982年我们开展了“矮变l号”小麦株高遗传的单体分析,在此基础上,本文进一步分析了“矮变l号”矮秆性状与世界上小麦三大矮源及“矮秆早”,所携带矮秆基因之间的关系及其遗传模型。 “Dwarf No.1” wheat is a natural mutant selected from “Dwarf Early” by Xi’an Agricultural Science Institute. Some domestic breeding units have been used as dwarf sources, and some of their dwarf genetic traits have also been studied both at home and abroad. In 1982, we carried out single inheritance analysis of the plant height of “Dwarf No.1” wheat. On this basis, we further analyzed the relationship between the dwarf traits of “Dwarf No.1” and the world’s three dwarf sources and “dwarf Early ”, carry the relationship between dwarfing genes and their genetic model.
