Abstract ABSTRACT The present investigation entitled “Genetic variability studies in garlic (Allium sativum L.)†was carried out at Vegetable Research Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Rabi season 2015-16. The experiment was laid out in RCBD with three replications comprising of twenty five 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 length, bulb breadth, bulb weight, clove length, clove breadth, clove weight, number of bulbs per kg, number of cloves per bulb, bulb yield per plot, bulb yield per hectare, total soluble solids and stemphylium blight intensity. Analysis of variance revealed highly significant differences among genotypes for all the characters under study. Genotypes viz., Kandaghat Selection, LGC-2, LGC-4, LGC-5, LGC-13 and LGC-22 were found promising in terms of yield and yield contributing characters and performed better than check variety. Genotypes viz., LGC-11, LGC-18 and LGC-19 were earliest in maturity. High percentage of total soluble solids was found LGC-1. Genotypes viz., Kandaghat Selection, LGC- 1, LGC-3, LGC-4, LGC-5, LGC-9, LGC-13, LGC-15, LGC-16, LGC-17, LGC-20, LGC-21 and LGC-22 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, number of bulbs per kg, bulb yield per plot, bulb yield per hectare 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 length, bulb breadth, bulb weight, clove length, clove breadth, clove weight whereas, negatively and significantly with number of bulbs per kg and number of cloves per bulb. The path coefficient analysis depicted that bulb weight had the maximum positive direct effect on bulb yield per plot. Genetic divergence plays vital role in partitioning the variability and genotypes were grouped in to four clusters and maximum inter cluster distance was recorded between III and II (9.399) and show the maximum variability.
