dc.description.abstract The aim of the present project is to investigate the effect of salinity on growth, biochemical parameters and fatty acid composition in six varieties of safflower as well as identification of stress tolerant variety under saline (8 d Sm-1) condition. It was observed that salinity significantly decreased the dry weight and fresh weight of safflower varieties. Nitrate reductase (NRA) and nitrite reductase (NiRA) activities were also reduced in response to salinity in all safflower genotypes but Thori78 and PI-387820 showed less reduction which could be a useful marker for selecting salt tolerant varieties. Under salinity stress, total free amino acids, reducing, non reducing sugars and total sugars increased in all varieties. Accumulation of sugars and total free amino acids might reflect a salt protective mechanism and could be a useful criterion for selecting salt tolerant variety. Comparison among safflower genotypes indicated that Thori-78 and PI-387820 performed better than the others and successful in maintaining higher NRA, NiRA and other metabolites thus were tolerant to salinity. Differential effect upon fatty acid synthesis was observed by different varieties under salinity stress but PI-170274 and PI-387821 varieties better maintained their fatty acid composition. It can be concluded from present studies that biochemical markers can be used to select salinity tolerant safflower varieties. en_US
