Water shortage and competition in water consumption are major challenges in irrigated-rice production. Hence, there is a need to develop a suitable rice cultivation system which use less water. Therefore, this preliminary research was carried out to study the possibility of coversion of irrigated system to aerobic. We tested 61 aerobic rice genotypes, in which were developed at International Rice Research Institute (IRRI), together with 5 diverse local checks such as Fajr, Neda, Tarom, Nemat and Hashemi. They were tested in Mazandaran and Guilan provinces in an augmented experiment design with 5 blocks (Mazndaran site). A variety of traits including headings (HDG), plant height (HT), number of filled (FG) and non-filled grain (NFG) per panicle, grain length (GL) and width (GW), 1000- grain weigth (TGW) some others were evaluated. Analysis of collected data showed that 8 genotypes had better performance than the others in aerobic condition for most of the traits in both experimental sites. Hence, these selected aerobic rice genotypes with Neda, the best local check, could be suggest to be used for further/details tests to select the best genotypes and develop related agronomic managements.
