Genetic Variability and Correlation Studies in Garlic (Allium sativum L.)

Abstract

With the aim to study genetic variability, heritability, genetic advance and correlation in eightyindigenousgarlic (Allium sativum L.) genotypes collected from different places of Uttar Pradesh. Experimental trial was conducted at Narendra Dev University of Agriculture & Technology, Kumaganj, Faizabad (U.P.) during rabi2015-2016. The experiment was conducted in augmented block design. Observations were recorded for twelve characteristics. The higher magnitude of coefficient of variation observed for width of leaf (cm), weight of clove (g), number of cloves per bulb, number of leaves per plant, plant height, length of leaf (cm) and diameter of bulb, at phenotypic levels. High heritability coupled with high genetic advance in percent of mean was recorded for number of cloves per bulb, length of leaf, Total soluble solid (T.S.S.), width of clove and bulb yield per plant. The length of leaf had highly significant and positive correlation with plant height, number of leaves per plant and diameter of bulb indicated that selection for these traits would be effective for the improvement of bulb yield per plant.
