Abstract
          The study developed some mutant populations and used Mpopulation to check DNA. Screening method was based on evaluation of agronomic traits of yield components. Most experiments were carried out at High Agricultural Technology Research Institute for Mekong delta (HATRI). OM6162 variety was exposed to 5 different levels of irradiation of 100, 200, 300, 400 and 50GY of Co60. The heritance interval based on correlation between yield and yield components of mutant lines was statistical significantly recorded. The yield of almost mutant lines from OM6162 was recorded with high yield at dose 300-400 GY. The amylose content, protein, glutine of lines was improved but with low variation. Two lines good for hight yield such as line 11 and line 7. These lines will be apply for breeding program.
