NOVELTY - A glutinous rice mutant obtaining method involves selecting species with no white belly, water content of 14.5% of japonica rice cultivars 9915. Mutagenesis is performed. The seeds are sowed in single planting manner and harvested as M1 generation seed. The M1 generation seeds are sown. The 12 strains of rice are divided into two groups of six, after rice plants died, screening to obtain M2 generation seeds, followed by screening M2 next generation seed, harvesting, selecting the highest average rate of white belly grains of different test point mutant strain as a white belly lines.    USE - Method for obtaining glutinous rice mutant.    ADVANTAGE - The method enables eliminating the impact on grain panicle vulnerable phenotype, improving the accuracy of phenotyping, screening ecological zones after planting with good genetic stability, in environmentally friendly manner.    DETAILED DESCRIPTION - A glutinous rice mutant obtaining method involves selecting species with no white belly, water content of 14.5% of japonica rice cultivars 9915. Mutagenesis is performed by soaking rice seeds into the phosphate buffer for 8 hours, and ethyl methane sulfonate for 16 hours, after mutagenesis, cleaning the rice seed with running water for 6 hours and soaking seeds in water for 48 hours to give mutagenesis seed. The seeds are sowed in single planting manner at 5000 per plant, harvest, and harvested as M1 generation seed. The M1 generation seeds are sown in accordance with lines, each 20, 6-7 leaf planting, work on behalf of M lines each planting row 12 Strain. The 12 strains of rice are divided into two groups of six, after rice plants died, ear from each group received 10 top seed moisture content of less than 15%, screening a white belly grain of more than 70% of the plant alone harvest to obtain M2 generation seeds, followed by screening M2 next generation seed a year or more in two different ecological zones in accordance with each of the lines 20 planting, harvesting and drying in indoor with white belly detects moisture of below 16%, determining comprehensive results of different experimental sites, selecting the highest average rate of white belly grains of different test point mutant strain as a white belly lines, selection of which the highest rate of white belly grains per plant, identified as white belly mutants.
