The experiment was laid out in RCBD with three replications comprising of thirty six diverse genotypes of garlic including Agrifound Parvati as check variety. The observations were recorded on various characters viz., plant height, number of leaves per plant, days to maturity, neck thickness, bulb weight, bulb breadth, bulb length, clove weight, clove breadth, clove length, number of cloves per bulb, number of bulbs per kg, weight of 100 unpeeled cloves, weight of 100 peeled cloves, bulb yield per plot, bulb yield per hectare, peeling index, drying percentage, total soluble solids, oleoresin content and stemphylium blight intensity. Analysis of variance revealed highly significant differences among genotypes for all the characters under study. Genotypes viz., Kandaghat Selection, LC-1, SG-30, LC-2 and LC-3 were found promising in terms of yield and yield contributing characters and performed better than check variety. Genotypes viz., G-189, G-282 and G323 were earliest in maturity. Maximum peeling index and drying percentage was recorded in G-282 and maximum percentage of oleoresin content in SG-10. LC-4 was found to have high percentage of total soluble solids and drying percentage. Genotypes viz., Kandaghat Selection, LC-1, LC-2, LC-3, LC-4, LC-5, SG-1, SG-2, SG-4, SG-9, SG-20, SG-21, SG-22, SG-26 and SG-27 exhibited field resistance against the stemphylium blight. High heritability in association with high genotypic coefficient of variability and genetic gain were recorded for bulb weight, clove weight, number of bulbs per kg, bulb yield per plot, bulb yield per hectare, oleoresin content and stemphylium blight intensity. Correlation studies revealed that yield per plot was positively and significantly associated with plant height, number of leaves per plant, days to maturity, neck thickness, bulb weight, bulb breadth, bulb length, clove weight, clove breadth, clove length, weight of 100 unpeeled cloves and weight of 100 peeled cloves whereas, negatively and significantly with number of cloves per bulb, number of bulbs per kg and drying percentage. The path coefficient analysis depicted that bulb weight had the maximum positive direct effect on bulb yield per plot.engarlic (Allium sativum L.,germplasm” ,Genetic evaluationThesis
