| Title : | EVALUATION OF RICE CULTIVARS IN DIFFERENT IRRIGATION TREATMENTS BASED ON SENSITIVE AND TOLERANCE INDICES |
| Abstract : | In order to evaluation rice cultivars in different irrigation treatments based on sensitive and tolerance indices, an experiment was conducted as two-factor factorial in a randomized complete block design with three replications at Rice Research Station of Tonekabon, northern Iran, in 2011. Seven drought resistance indices include susceptible stress index (SSI), tolerance index (TOL), stress mean productivity (MP), geometric mean productivity (GMP), stress tolerance index (STI), yield index (YI) and yield stability index (YSI) were applied on the basis of seed yield in non stress and drought stress conditions. Based on different drought indices, Shiroudi cultivar had the best rank with low standard deviation. The results indicated that it has stable yield performance. Bi-plot display cleared superiority of this genotype. Results showed MP, GMP, YI and STI indices were more effective in identifying high yielding cultivars in diverse water scarcity. Selection of the best Iranian rice variety and determination of best irrigation management based on yield can use these tolerant and sensitive indices in different irrigation position. |
