Stability analysis of high yielding varieties of black gram (Vigna mungo L. hepper)

Black gram is grown throughout India. Most of the varieties show great degree of genotype x environment interactions for most desirable characters. Field experiment was conducted using fourteen genotypes of black gram during kharif season, 2009 and 2010. The data were analyzed according to the stability model as suggested by Eberhart and Russell (1966). The pooled analysis of variance due to genotypes was found highly significant for all the characters indicating genetic variability among the genotypes. Highly significant pooled deviation for all the characters except 100 seed weight was observed in all the genotypes that fluctuated significantly from their respective linear path of response to environments. From the estimated parameters of stability in the present study, genotypes RBU1012 and Pant U-19 were considered to be the most stable genotypes. Environments E-6 was the best for yield and its components while Environment E-1was the lowest for yield and its components.
