EFFECT OF DIFFERENT SALINE LEVELS ON GROWTH AND YIELD ATTRIBUTES OF MUTANT RICE

-1 , 3 dSm -1 with a control were imposed in this experiment. The results indicated that all the growth and yield contributing characters of rice genotypes such plant height, number of tiller hill -1 , effective tillers hill -1 , panicle length, filled grain panicle -1 , 1000-grain weight (g), grain yield hill -1 (g) decreased with increased levels of salinity compared to control. Among the genotypes, MR-219 showed best performance in respect of yield and yield contributing characters up to 6 dSm -1 and showed Y-1281 intermediate status. The genotypes Q-31 and Y- 1281 showed its susceptibility to salinity stress. Thus MR-219 was found best salt tolerant genotype than others.
