| 摘 要： | 采用14个大麦染色体标记性状材料，对大麦突变体76-2104进行了多节矮秆性状在染色体上的定位研究。研究结果表明:(1)多节矮秆性状分别由一对隐性基因控制。(2)控制多节矮秆两对性状的基因位于第四染色体上。长节间矮生(Sid)与多节的交换值为12.41士2.05%。三叉芒K与多节、矮秆两对性状之间的交换值分别为47.80士4.07%和42.26

| Abstract: | 14 crosses were made with multi-noded and dwarf mutants 76-2104 and marker stocks in barley in 1993. The genetics and genes localization were studied through F1、F2 and F3 generations the results of two years(1993-1995) were shown:(1)The multi-noded and dwarf characters of 76-2104 are controlled by |
