Character association and path analysis in twenty genotypically diverse indigenous genotypes of garlic (Allium sativum L.) were studied at the Central Institute of Temperate Horticulture, Srinagar during the years 2010 and 2011 for nine important characters. Total bulb yield showed positive and significant genotypic and phenotypic associations with plant height, number of leaves per plant, pseudo-stem length, bulb weight and number of cloves per bulb, indicating that selection based on these traits will help increasing the yield of garlic. Path coefficient analysis provides an effective means of a critical examination of specific force action to produce a given correlation and measure the relative importance of each factor. In this analysis bulb yield was taken as dependant variable and rest characters were considered as independent variable. Bulb weight showed high positive and direct effect and significant positive correlation with total bulb yield. Therefore, bulb with higher weight should be considered in selection criteria for increasing the total bulb yield and emphasis should be given for selecting the genotypes with higher bulb weight. Overall path analysis indicated that direct effect of bulb weight and equatorial bulb diameter and indirect effect of plant height, number of leaves per plant, pseudo stem length, polar bulb diameter, equatorial bulb diameter, number of cloves per bulb and average weight of 50 cloves should be considered simultaneously for amenability of total bulb yield.

Character association and path analysis were performed for black seed cultivars using a split-plots design based on RCBD with three replications. Three cultivars (‘Varzaneh’, ‘Semirom’ and ‘Mobarakeh’) were studied under three levels of irrigation (normal irrigation, irrigation with drought stress before and after flowering). Under normal and abnormal irrigations the relation of seed yield and three characters biological yield, number of capsule per plant and thousand seed weight were high, positive significantly (p≤0.01); the relation between yield and number of sub branch was positive significantly (p≤0.05). In terms of abnormal irrigation there was a positive significant correlation between essence percent and yield (p≤0.05). Under normal irrigation the most direct effect of traits on yield was obtained from biological yield (0.778) followed the number of capsules per plant (0.245). The most indirect effect of traits on yield was obtained from biological yield through thousand seed weight (0.576) followed stem diameter through biological yield (0.468). Under water deficiency conditions the most direct effect of traits on yield was obtained from biological yield (0.811) followed the number of capsules per plant (0.231). The most indirect effect of traits on yield was obtained from biological yield through thousand seed weight (0.562).
