Abstract
The present investigation entitled “Genetic evaluation of local genotypes of Garlic (Allium
sativum L.) under low hills conditions of Himachal Pradesh” was conducted at the experimental farm”
was carried out at Vegetable Research Farm, Department of Vegetable Science, College of Horticulture
and Forestry, Neri, Hamirpur (H.P) during season, 2021. Thirty eight diverse genotypes of garlic
comprising of local collections along with standard checks Kandaghat Selection were evaluated in
Randomized Complete Block Design with three replications to ascertain extent of variability, heritability,
genetic advance and gain, correlation and path coefficient analysis for yield and other horticultural traits
among the genotypes. Analysis of variance revealed significant differences among all the genotypes for
all the characters under study. Genotypes viz., LGCOHF-LGCOHF-35, LGCOHF-32, LGCOHF-9 and
LGCOHF-18 genotypes performed better than the check variety Kandaghat Selection for number of
leaves per plant, bulb breadth, bulb length, clove length and days to maturity. LGCOHF-32, LGCOHF18, LGCOHF-31 and Kandaghat Selection exhibited field resistance against the stemphylium blight. High
heritability coupled with high to moderate genetic gain for most of the characters, indicating the effect of
additive gene effect for the expression of different characters. Bulb yield per plot was positively and
significantly associated with majority of the yield contributing characters whereas, negatively and
significantly associated with number of cloves per bulb. Positive and direct effect of bulb yield per plot
was observed through bulb weight followed by total soluble solids, drying percentage and bulb breadth
