Aerobic rice is a new type of rice adapted to aerobic soil. This study was conducted to evaluate aerobic rice utilizes multivariate statistical techniques in a randomized complete blocks design with three replications in Shavoor Khuzestan Agricultural Research Center in 2014. In this experiment, yield and yield components of 9 aerobic lines plus Danial cv. were examined. Results showed that there was significant difference in 1% probability level between lines the trait of the number of primary branches, panicle weight, number of grains per panicle, panicle length, plant height, panicle fertility percent, 1000 grain weight and days to heading. The narrow sense heritability of 18% in yield to 49% in panicle fertility percent was variable. There was a positive and significant correlation between grain yield with panicle weight, number of grains per panicle and panicle fertility percent. Cluster analysis basis ward’s method stated that IR81025-B-347-3 was in a group and other aerobic lines with Daniel in the other group. Aerobic line IR81025-B-347-3 with having the highest number of primary branches, panicle length, number of grains per panicle, panicle weight, panicle fertility percent and grain yield and located in the desirable area biplot as the best lines in terms of morphological traits in aerobic soil conditions and intermittent irrigation was identified as high-performing of line for further research.
