【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更多还原

【Abstract】 In order to study the inheritance of poly-row-and-branched spike (PRBS) in barley, the row types of F 1s, F 2s, F 3s 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.更多还原
