The genotypic variations among the characters related to growth, yield, and quality were investigated in 14 garlic genotypes. For all traits, the analysis of variance indicated a highly significant difference among the genotypes, emphasizing the presence of variability. The phenotypic coefficients of variations were found to be slightly greater than the genotypic coefficients of variations, showing that apparent variation was influenced by the growing environment as well as presence of genetic variability. High heritability and high genetic advance were observed in oleoresin content, number of cloves bulb-1, weight of 10 cloves, clove breadth, bulb yield hectare-1 at four months after storage, bulb yield hectare-1, bulb weight, bulb yield plot-1, number of bulbs Kg-1, ascorbic acid, TSS, bulb breadth, clove length. The genotypes Pundibari Local and Phule Nilima proved their superiority with respect to yield and quality attributing traits. The presence of additive gene action for the expression of these attributes, as well as high heritability and genetic advance gave a clear picture of the traits during the selection process, indicating that the cultivar Pundibari Local may be selected for further breeding programme and can be recommended for cultivation among the growers of this region.
