STUDIES ON GENETIC VARIABILITY AND COMPONENT ANALYSIS IN RAGI (ELEUSINE CORACANA GAERTN.)

Published on

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.
