Ninety-nine landraces of kharif sorghum were evaluated for six seed quality characters. The study revealed that the characters grain mold rating and seed hardness showed high GCV and PCV values indicating thereby large amount of variation in these characters. All the characters showed close GCV and PCV values indicating less influence of environment of these characters. The high heritability estimates were observed for all the characters indicating that these characters would respond positively to selection. The high values of expected genetic advance over mean were recorded for the characters like threshed grain mold rating, seed hardness and electrical conductivity. The threshed grain mold rating and seed hardness exhibited high heritability along with high value of expected genetic advance per cent over mean which indicated the importance of these traits for selection. High values of heritability along with low value of expected genetic advance were observed for the characters like electrical germination percentage of seed, vigour index of seed and specific gravity of seed and heterosis breeding can be fruitfully exploited improving these characters.
