摘要: 为研究大麦多棱分枝突变的遗传,对四个杂交组合(六棱×二棱、多棱分枝×二棱、多棱分枝×六棱和六棱×多棱分枝)的F1、F2、和F3的棱型进行了调查分析。结果表明,一对隐性基因(mm)控制多棱分枝,并且对控制二棱和六棱的基因具有隐性上位性作用。

Abstract: In order to study the inheritance of poly-row-and-branched spike (PRBS) in barley, the row types of F1s, F2s, F3s of four crosses ( six-row × two-row, PRBS × two-row, PRBS × six-row and six-row × PRBS ) were investigated and analyzed. The results showed that one pair of recessive genes controls the PBRS mutant trait, which has recessive epistasis on the genes controlling two-row vs. six-row.
