The extent of genetic variability present in any base population is most important for the success of breeding programme. Greater the variation in the material, better is the chance for selecting promising and desired types. Hence, thirty two genotypes of little millet were studied for genetic variability study at Hill Millet Research Station in randomized block design for different morphological and biochemical traits viz., days to 50 % flowering, days to maturity, zinc content (mg), plant height at maturity (cm), 1000 seed weight (g), fiber content (%), number of productive tillers per plant, Protein content (%), number of branches per panicle, ash content (%), panicle length (cm), fat content (%), grain yield per plant(g), calcium content (mg), straw yield per plant (g), iron content (mg). The results of the present study indicated all the sixteen characters had a wide range of variability in the different little millet genotypes. High estimates of genotypic and phenotypic variance were observed for days to 50% percent flowering, plant height at maturity, panicle length, straw yield per plant, days to maturity and calcium content. High genotypic and phenotypic coefficient of variation found in number of productive tillers per plant, grain yield and straw yield per plant. In the present study the high heritability coupled with high genetic advance was observed for number of productive tillers per plant, grain yield per plant, straw yield per plant, 1000 seed weight, protein content, ash content, fat content, calcium content, iron content and fiber content which, indicated that these characters are largely governed by additive genes and selection for improvement of such characters could be rewarding.
