Studies on Genetic Variability and Correlation between Economic characters in Dioscorea floribunda. Mart and Gal.

Abstract

Variability was estimated for 30 clones of Dioscorea floribunda. The genotypic coefficient of variability was higher in diosgenin yield per plant, number of fingers per tuber and diosganin percentage. Heritability was observed to be moderate to high in almost all the characters and high values of heritability were associated with higher genetic advance sxpressed as a pereantage of mean for diosgenin yield and diosgenin percentage The genotypic correlation coefficients between diosgenin yield per plant and closgenin percentage, diy tuber weight, fresh tuber weight, girth of tuber at lower portion was observed to be positively significant Diosgenin percentage was negatively, but weakly correlated to dry tuber weight per plant, fresh tuber woight per plant, girth of tuber at lower portion and to number of fingers pes tuber. Dry tuber weight per plant, fresh tuber weight per plant, girth of tuber at lower portion and number or fingers par tuber were positively significant among each other.
