To study genotypic and phenotypic correlation and path co-efficient for seven characters were studied in 34 different local genotypes of ashwagandha. Results indicated that ischolar_main yield was significantly and positively correlated associated among themselves except ischolar_main branches with seed yield. Path co-efficient analysis showed highest positive direct and indirect effect of plant height and stem branches on ischolar_main yield. Indirect effects of other component characters were high through plant height and stem branches on ischolar_main yield. Selection for high plant height and stem branches appeared to be useful for improving ischolar_main yield.

Abstract


To study genotypic and phenotypic correlation and path co-efficient for seven characters were studied in 34 different local genotypes of ashwagandha. Results indicated that ischolar_main yield was significantly and positively correlated associated among themselves except ischolar_main branches with seed yield. Path co-efficient analysis showed highest positive direct and indirect effect of plant height and stem branches on ischolar_main yield. Indirect effects of other component characters were high through plant height and stem branches on ischolar_main yield. Selection for high plant height and stem branches appeared to be useful for improving ischolar_main yield.
