dc.description.abstractThe present investigation entitled “Evaluation of Garlic Genotypes for Horticultural Traits” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi, 2022-23. Thirty-five genotypes of garlic along with one check variety (Solan Selection) were evaluated for morphological characters based on DUS along with analysis of various horticultural traits. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications and the genotypes were morphologically classified based on thirty- one DUS characters. Analysis of variance for horticultural traits revealed significant differences among all the genotypes for most of the characters under study. Genotype LGC-20 performed best in terms of yield and other horticultural traits closely followed by LGC-2, LGC-22 and LGC-15. These genotypes were significantly superior than the check variety i.e., Solan Selection for bulb yield along with number of cloves per bulb, bulb equatorial and polar diameter, clove weight and clove size. Hence, these genotypes should be tested in multi-locational and multi-year trials so that the most superior and stable genotype(s) can be recommended for commercial cultivation. Among various parameters of variability, bulb weight, clove weight and pseudostem width and leaf width had high values of coefficients of variation as well as high heritability coupled with high genetic gain indicating the prevalence of additive gene action. Correlation coefficient depicted that number of cloves, clove weight, clove size, clove diameter,bulb equatorial and polar diameter, number of leaves per pseudotstem, leaf length, leaf width, pseudostem length, days to maturity and pseudostem width were significantly and positively correlated with bulb weight. Thus, selection of genotypes on the basis of these traits would be effective in improving bulb yield. The maximum positive direct effect on bulb weight was contributed by bulb equatorial diameter followed by pseudostem width, number of cloves, bulb polar diameter, days to maturity, clove diameter, clove weight and leaf length. Thus, improvement in these characters will lead to higher bulb weight in garlic. Genetic divergence studies revealed that hybridization between genotypes of cluster II and IV will be more rewarding for getting superior genotypes.
