Abstract:

An experiment was conducted to assess correlation and path analysis in 156 genotypes and 4 checks of garlic grown in Augmented Randomized Block Design at Vegetable Research Station, Junagadh Agricultural University, Junagadh during rabi season of 2015-2016. The observations were recorded on 18 characters viz., plant height (cm), number of leaves per plant, leaf length (cm), leaf width at middle portion (cm), days to maturity (days), pseudostem height (cm), collar thickness (cm), bulb collar diameter (cm), bulb equatorial diameter (cm), bulb polar diameter (cm), bulb weight (g), number of cloves per bulb, clove weight (g), clove length (cm), clove polar diameter (cm), clove equatorial diameter (cm), total soluble solids (%) and bulb yield (kg/ha). In general, the estimates of genotypic correlation were higher than the corresponding phenotypic correlation coefficient. It may result from the modifying effect of environment on the association of characters at genotypic level. The bulb yield had significant positive correlation with characters like with plant height, number of leaves per plant, leaf width at middle portion, pseudostem length, bulb collar diameter, bulb equatorial diameter, bulb polar diameter, bulb weight and clove length, clove polar diameter and clove equatorial diameter. From these associations, it appears that higher bulb yield can be obtained by increasing these characters. Path coefficient analysis revealed that the characters like plant height and clove polar diameter had high direct effect on bulb yield. These above characters also had positive indirect effect on each other. Plant height, number of leaves per plant, leaf width at middle portion, pseudostem height exhibited positive and indirect effects on bulb yield via plant height, leaf length, leaf width at middle portion, days to maturity, pseudostem height, bulb equatorial diameter, bulb polar diameter, bulb weight, number of cloves per bulb, clove weight and clove polar diameter, clove equatorial diameter and total soluble solids. Bulb collar diameter, bulb equatorial diameter, bulb polar diameter, bulb weight, clove length, clove polar diameter and clove equatorial diameter contributed indirectly by giving positive indirect effects on bulb yield through plant height, leaf width at middle portion, bulb equatorial diameter, bulb polar diameter, bulb weight, number of cloves per bulb, clove polar diameter, clove equatorial diameter and total soluble solids.
