Description The present investigation entitled “Study on garlic (Allium sativum L.) genotypes under Chhattisgarh plains” was conducted at Horticulture Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Rabi season of 2012-2013.
Experiment was laid out in Randomized block design and replicated thrice. Data were analysed to work out the genetic variability, heritability, genetic advance, character association and path analysis for the characters plant emergence percentage, plant height (cm), collar height (cm), collar thickness (cm), number of leaves per plant, fourth leaf length (cm), fourth leaf width (cm), polar diameter (cm), equitorial diameter (cm), neck thickness (cm), average bulb weight (g), number of cloves per bulb, weight of 10 outer cloves (g), marketable yield (t/ha.), TSS, total yield (t/ha.)
Analysis of variance revealed that the mean sum of squares due to genotypes were significant for all the characters. Estimates of genetic parameters for various characters revealed that relative magnitude of genotypic co-efficient of variation in general, was higher for marketable yield per hectare, total yield per hectare, weight of 10 outer cloves, plant emergence, average bulb weight and number of cloves per bulb.
Heritability estimates in general were high for most of the traits showing preponderance of additive genetic variance. High heritability coupled with high genetic advance as percentage of mean was in general, high for plant emergence

percentage, collar height, collar thickness, fourth leaf length, polar diameter, equitorial diameter, neck thickness, average bulb weight, number of cloves per bulb, weight of 10 outer cloves.
The association study among different characters revealed that selection for bulb yield should be based on marketable yield, plant emergence, number of leaves per plant, plant height, equitorial diameter and average bulb weight.
Path coefficient analysis revealed that marketable yield had the highest direct effect followed by equatorial diameter, plant height, average bulb weight, weight of 10 outer cloves and neck thickness. Hence these components should be considered as selection criteria in garlic improvement programmers for Chhattisgarh plains.
