摘要/Abstract

摘要： 在普通小麦地方品种自然群体中天然存在促进小麦-外源杂种部分同源染色体配对的基因phKL。本研究比较了phKL基因与人工Ph基因突变系诱导小麦-Aegilops variabilis及小麦-黑麦杂种部分同源染色体配对的作用大小。研究结果表明，诱导小麦- Ae. variabilis(或黑麦)部分同源染色体配对作用的顺序是ph1b > phKL > ph2b > ph2a，即phKL基因的作用介于Ph1与Ph2突变体之间。

Abstract: In natural populations of common wheat landrace, there has a phKL gene promoting homoeologous pairing of wheat-alien hybrids. In this study, the effects were compared among phKL, ph1b, ph2a and ph2b on homoeologous pairing of wheat-alien hybrids. The effects were indicated as ph1b > phKL > ph2b > ph2a, i. e. phKL gene was situated between gene mutants of Ph1 and Ph2.
