一、前言在世界上许多大麦育种计划中,已普遍利用拟直立型突变体(erectoides muntante)选育高度抗倒伏的矮秆大麦品种。关于拟直立型大麦突变体,甚至是几个染色体连锁群上许多位点的等位基因系列,都已进行了遗传学鉴定。但是,类似的突变体在小麦育种上的利用则还刚刚开始。目前,只在少数育种计划中应用,而且只涉及有限的几个突变体,可能是六个广为利用的、来源于自 I. INTRODUCTION In many barley breeding programs around the world, erectoides muntante has been used to breed highly resistant lodging barley varieties. Genetically identified allelic sequences have been identified for the pseudo-upright barley mutants, and even for many loci on several chromosomal linkage groups. However, the use of similar mutants in wheat breeding has just begun. At present, only a few breeding programs are applied and only a limited number of mutants are involved, possibly six widely available, from
