STUDIES ON GENETIC VARIABILITY AND COMPONENT ANALYSIS IN RAGI (ELEUSINE CORACANA GAERTN.)
Main Article Content
Abstract
Forty genotypes of ragi were evaluated for productivity related traits. Him Ragi 20, Him Ragi 23, GE 624 and GE 2675 were high yielders. Phenotypic coefficients of variability were slightly higher than the corresponding genotypic ones. Grain yield/plant, harvest index, biological yield/plant, lllOO-grain weight, finger length, fingers/ear, tillers/plant and leaf area were controlled by additive gene action. Dominance and epistatic effects were of considerable value for inheritance of days for maturity and flowering. Nonadditive gene action was important for plant height and grains/ear. Grain yield/plant was found to be positively associated with all the traits except flowering days. Path analysis revealed positive and direct effect of biological yield, harvest index and maturity duration on grain yield.
