Abstract:
The present investigation on “Genetic variability, heritability and genetic advance in garlic (Allium sativum L.) Genotypes” was carried out at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, during the Rabi season of 2020-2021. The experimental material for the study comprised of twenty-five genotypes. These genotypes were sown in Randomized Block Design in three replications to estimate the genetic variability, heritability and genetic advance. Analysis of variance indicated the presence of considerable amount of variability among the genotypes for all the traits studied. On the basis of mean performance Gulbarga local was found to be best performing genotype with highest bulb yield per hectare (6.3 t/ha). Higher estimates of PCV and GCV were observed for number of cloves per bulb followed by average bulb weight, clove width, dry weight of plant, bulb yield per hectare, neck diameter of bulb and fresh weight of plant, indicating the presence of high variability, therefore, simple selection would be helpful for improvement of these characters. High heritability estimates coupled with high genetic advance recorded for fresh weight of plant, dry weight of plant, harvest index and bulb yield per hectare which suggests that these traits can aid in simple selection which could be helpful for further crop improvement.
