Studies on genetic variability in little millet (Panicum sumatrense)

Abstract

Genetic parameters were studied for yield, yield attributing and physiological traits in 50 little millet genotypes. The genotypic coefficient of variation (GCV) for all the traits studied were lesser than the phenotypic coefficient of variation (PCV) indicating that interaction of genotypes with environment. High GCV, PCV coupled with high heritability and genetic advance as per cent of mean was observed for leaf area index at panicle initiation, specific leaf weight at panicle initiation, harvest index, main panicle weight and fodder yield plot-1 and moderate heritability coupled with high genetic advance as per cent of mean was found in grain yield plot-1 indicating the role of additive gene action in governing the inheritance of these traits. Phenotypic selection based on these traits can be improved through simple selection.
