ABSTRACT
Little millet is a small grained, annual, warm weather cereal which is the staple food for millions in many parts of the world especially among tribal. The present study aims to reveal the existence of genetic variability and importance of some quantitative traits in the 64 elite genotypes. The objectives were to assess the variability, heritability, and genetic advance for yield and 12 yield component characters. Highly significant mean sum of squares due to genotypes and wide range of variability were noticed among the genotypes for all the characters studied. Phenotypic coefficient of variation was higher than the corresponding genotypic coefficient of variation for all the characters studied. High values for phenotypic and genotypic coefficients were recorded for plant height, number of tillers per plant, flag leaf length, flag leaf width, panicle length, thousand seed weight and grain yield per plant. All the characters recorded high heritability in the present study indicated that these characters were relatively less influenced by environmental factors and phenotypic selection would be effective for the improvement of these characters. All the characters recorded high heritability coupled with high genetic advance which indicated that these characters were governed by additive genes and selection would be effective for improvement of such characters. Since there is significant variability observed in all the little millet genotypes, this could be used for genetic improvement through selection and hybridization.
Key words: Little millet, Genetic variation, Heritability, Genetic advance
