| Abstract | ||
| The experiment was conducted to evaluate 54 heat tolerance rice genotypes at Multi-locations including 9 locations in 8 countries (China, Republic of Korea, Philippines, Thailand, Egypt, Senegal, Iraq and besides tow location in India). The target of this study was to select promising genotypes that could have highest grain yields (t/ha) and early maturity and stable by using joint regression analysis (JRA). The Results showed that there were significant differences in flowering date and grain yield (t/ha) characters among genotypes and locations at (0.05). 29 Genotypes superiority in grain yield (t/ha) for nine environment and 11 of 29 genotypes showed their superiority in Iraqi environment. Joint Regression Analysis (JRA) show that 6 genotypes of 11 genotypes which superiority in grain yields (t/ha) have medium stable in Iraqi environment. | ||
