| Abstract: | The seeds of indica restorer line Jinhui10 were treated with ethyl methane sulfonate(EMS),and twenty-eight semi-dwarf mutants were discovered,and four of which were distinct.The panicles of d11 and d24 were sheathed slightly in the stem with-2.7 and-2.6cm respectively,but their agronomic characters were less influenced compared with other semi-dwarf mutants,and the panicle number per plant was the same.The wild type Jinhui10 was sensitive to the treatment of GA3,whereas d9 and d18 were GA3-insensitive.All t... |
