摘要/Abstract

摘要： 宛原50-2是一个株高比常用矮矮，农艺性状较好的新品系。通过21个单体系F1、F2的株高和F2的赤霉酸反应及测交分析，发现该品系携带有4对或4对以上的矮秆基因。其中Rht IS位于染色体4B**上；Rht8和Rht9分别位于染色体2D和7B上；一对可能通过诱变产生的对赤霉酸不敏感的矮秆基因，暂命名为Rht（Wan），位于染色体4D上。

关键词: 小麦，矮秆基因，基因定位

Abstract: Wanyuan50-2, a new dwarf line of wheat, is shorter than the normal dwarfing sources and with good agronomic characters. It was found that there are four of more than four dwarfing genes in this line. They are Rhtls on chromosome 4B, Rht 8 on 2D, Rht9 on 7B, and Rht(Wan), a new GA-insensitive dwarfin

Key words: Wheat (Tr.aestivum), Dwarfing genes, Gene location
