IDENTIFICATION AND ANALYSIS OF EMS-INDUCED DWARF MUTANTS IN RICE
摘要
Abstract
The seeds of indica restorer line Jinhuil0 were treated with ethyl methane sulfonate (EMS), and twenty-eight semi-dwarf mutants were discovered, and four of which were distinct. The panicles of dl 1 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 Jinhuil0 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, dl 1, d18, and cl24 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 GA. biosynthesis and signaling.关键词
