Abstract:

To provide materials for the research of rice functional genomics, dry seeds of ‘Zhonghua11’and LR001 were induced with 60Co γ-ray, then these seeds and ‘Jinhui21’ M1 seed, induced by ethyl methane sulfonate (EMS) of 1%, were induced with 1% EMS. Through the screening to M2, seven hundred and sixteen mutants, including the changed organ of leaf, stem, panicles and grain, etc, were identified. Among these ones, some were of great value in research, such as no-tillering, more-tillering, albino, mini-plant, thin grains, flower organs, etc. More types of mutants were obtained, with a frequencies of mutation mean of 1.79%, and all emerged in the three varieties in double induction. This indicated that the double mutation technology might provide a lot of mutants for functional genomics research.
