Title: IDENTIFICATION AND ANALYSIS OF EMS-INDUCED DWARF MUTANTS IN RICE
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 the internodes of d9 were shortened,but only the upmost internode of d18 was shortened with the average length of the upmost internode of 0.31cm.Genetic analysis indicated that the mutant characters of d9,d11,d18,and d24 were all controlled by one recessive nuclear gene.These results not only broaden the diversity of dwarfism resources but also provide the materials to study GAs biosynthesis and signaling.
