Genetic variability and path analysis in mungbean

Ch. Mallikarjuna Rao, Y. Koteswara Rao, M Venkateshwara Reddy

Abstract

Genetic variability, Correlation and path coefficient were studied in 60 mungbean genotypes during rabi 2002–03. High estimates of GCV, PCV, heritability and genetic advance were recorded for seed yield per plant, biological yield per plant, clusters per plant and pods per plant. The estimates of genotypic correlation revealed that seed yield had positive and highly significant association with pods per plant, biological yield per plant and harvest index. Path coefficient analysis indicated that pods per plant, biological yield and harvest index had maximum direct contribution on seed yield.
