Cottonseeds (Gossypium hirsutum L.) from lines 84027 and 84033, characterized by enhanced salt tolerance, and their parental line DP62 were studied qualitatively and quantitatively to determine fatty acid composition and proximate analysis. Proportions in fatty acid composition were found to be modified as a result of the salt selection-breeding program. Linoleic acid (18:2) was higher in both salt tolerant lines while palmitic acid (16:0) was lower in line 84027. Significantly different unsaturated/saturated fatty acid ratios, 3.13, 3.20, and 3.59 were obtained from genotype DP62, 84033, and 84027, respectively. Other parameters studied also reflected genotypic variability, including crude protein, crude oil, crude fiber, ash, nitrogen free extract, and carbohydrates content. This research may contribute to establishing a relationship between the unsaturated/saturated fatty acid ratio of a particular genotype and its ability to maintain physiological and biochemical functions under salt stress.
