A study was undertaken to determine the extent of genetic variability for grain yield and eight other quantitative characters and two qualitative characters in 40 genotypes of finger millet. The analysis of variance revealed significant differences among genotypes for all the characters. High genotypic coefficient and phenotypic coefficient of variation was recorded for grain iron content followed by grain yield per plant, number of tillers per plant, number of productive tillers per plant, main earhead length, number of fingers per earhead, grain calcium content, 100 ml volume weight of grain. The lower magnitude of GCV was observed plant height, days to 50 per cent flowering and days to maturity. The high estimates of heritability in broad sense was observed for grain iron content followed by grain yield per plant, 100 ml volume weight, main earhead length, number of tillers per plant, grain calcium content, number of fingers per earhead, days to 50 per cent flowering, days to maturity and plant height. Highest estimate of GA was noticed for grain calcium content. While, medium to low estimates of GA observed for 100 ml volume weight, days to maturity, plant height, days to 50 per cent flowering, grain yield per plant, grain iron content, main earhead length, number of tillers per plant and number of productive tillers per plant. High heritability coupled with high genetic advance was recorded in grain yield per plant, 100 ml volume, which indicated the predominance of additive gene effects. Improvement in these characters could be exercised by simple selection due to fixable additive gene effects.
