Biometrical analysis of yield and its contributing characters was made for yard long bean with the use of sixty two genotypes. Phenotypic variation was greater than that of genotypic and environment variations for all the characters concerned. Minute differences between genotypic and phenotypic coefficient of variation indicated less environmental influences on considered characters. | Study on genetic variability for yield and quality of different genotypes of yard longbean Vigna unguiculata sub sp. sesquipedalis L. Verd.
