A study was undertaken to estimate correlation coefficient between seed size, starch content and its composition together with the estimation of genetic variability in a range of chickpea genotypes. Among the 15 chickpea genotypes of diverse origin analyzed highly significant difference which ranged from 191 mg to 496 mg were found for weight per seed. Relatively small difference from 38-45% of seed dry weight were found for total starch whereas values for amylose and amylopectin percentage of starch varied from 32-42% and 58-68% respectively. Within genotype variation for starch content and amylose percentage was insignificant which could be due to experimental error. However, there were considerable difference within genotype for seed size in almost all the lines. The correlation between seed size and starch content and composition was negligible although positive and there was no association starch percentage and amylose percentage of starch.
