High temperatures during reproductive stages causes male sterility and fertilization failures resulting in yield decreasing dramatically. The purpose of this study was selecting rice mutant lines that tolerant to high temperatures during reproductive stages. The simulation tunnel for global warming condition was controlled gradually increasing temperature from the real environment temperature (25-30 degrees Celsius) in the morning to 40 to 45 degrees Celsius at 10 am and remain this condition for 6 hours and then the system in the tunnel was decreased the temperature to equal outside temperature at night time. For the fast screening of Hom nin mutant1,500 lines found that the mutants lines showed both tolerance and non-tolerance for high temperature...
