Abstract: (2837 Views)

The North of Iran, especially Mazandaran province supplies a large portion of Iran's rice consumption. During the growing season of rice, yield components are affected by environmental conditions and the actual yield of a cultivar will depend on its genotype and response to environmental conditions. In this study to identify stable genotypes, 11 promising lines of rice along with their parents (Deilamani, Sepidrood, Sange-Tarom and Neda) were planted in three different regions of Mazandaran Province, namely Sari Agricultural sciences and natural resources university, the Rice Research Institute of Mazandaran in Amol and the Rice Research Station of Chaparsar, Tonekabon. Based on AMMI analysis, environment, genotype and their interaction had significant effect on yield and explained 27.58%, 30.32% and 21.93%, of the total variation respectively. According to AMMI biplot analysis, Neda and Line 5had specific adaptability to Amol region, Line 117 to Sari, and Sepidrood and Line 48 were specifically adapted to Tonekabon. Based on the results, line 117 with an average yield of 6 t ha^-1 was the most stable genotype that could be recommended for all of the studied regions.
