Abstract:
The present study was conducted to know genetic variability for growth, yield and quality attributes in garlic (Allium sativum L.) at herbal garden of Department of Horticulture, College of Agriculture, UAS, Raichur with twenty eight garlic genotypes with three replications to know the extent of genetic variability, heritability, genetic advance as percent mean. High degree of variation was observed for all the characters studied. Phenotypic co-efficient of variance (PCV) in general was higher than genotypic co-efficient of variance (GCV) with smaller differences which reflects the role of environment is very less. Genotypic coefficient of variation varied from 1.97% (pH) to 49.49% (reducing sugar), while phenotypic coefficient of variation varied from 3.42% (pH) to 49.60% (reducing sugar) among the various characters studied. Higher estimates of heritability found for most of the characters studied. Genetic advance as percent mean was observed as moderate and high for most of the characters except pH and sprouting percent. The characters are governed by additive gene effects. Selection on the basis of the characters will be more useful for the crop improvement towards attaining higher yield.
