 ABSTRACT

A set of one fifty genotypically diverse genotypes of garlic were studied for assessment of genetic variability, heritability and genetic advance for fifteen yield contributing and economically important traits at Vegetable Research Station, Junagadh Agricultural University, Junagadh, during rabi 2016-17. The analysis of variance revealed significant difference among the genotypes for the traits, number of leaves per plant, leaf length (cm), leaf width at middle portion (cm), bulb polar diameter (cm), bulb weight (g), number of cloves per bulb, clove weight (g), clove length (cm), bulb yield (kg/ha) and pseudo stem height (cm). Based on the mean performance, the genotypes RGP-498, RGP-501, RGP-487, RGP-619 and RGP-114 were identified as most promising genotypes for bulb yield per plant. In general, estimates of phenotypic coefficient of variation (PCV) were found higher in magnitude than corresponding genotypic coefficient of variation (GCV) for all the traits studied. The higher magnitude of coefficient of variation at genotypic as well as phenotypic levels was observed for bulb yield followed by bulb weight, while high heritability was observed for clove weight. The highest genetic advance was recorded for bulb yield, while clove weight had high heritability coupled with moderate genetic advance as per cent of mean. It is suggested that selection for these traits will directly increase bulb yield per plant, in garlic crop.

Key words:Garlic, Genetic variability, Heritability, Genetic advance, Yield.
