Genetic Variability Assessment in garlic (Allium sativum L.) Genotypes

Abstract

The present investigation was carried out to estimate genetic variability among eighty genotypes/hybrid of Garlic for twelve characters comprised of bulb yield and its contributing characters. These genotypes were planted in augmented block design during Rabi-2015-16 at Main Experimental Station of Department of Vegetable Science, Narendra Deva University of Agriculture, Kumarganj, Faizabad (U.P.). On the basis of mean performance, the genotype NDG-33 was the highest yielder followed by NDG-32 and minimum was found in NDG-54. Based on mean performance NDG- 33, NDG-32. NDG-26, NDG-9 and NDG- 34 were identified as high yielder for bulb yield per plant. These genotypes may further be utilized in breeding programme aimed at improving bulb yield in garlic. Analysis of variance indicated presence of considerable variability for all the twelve characters. The estimates of phenotypic co-efficient of variation (PCV) were higher than the genotypic co-efficient of variation (GCV) for all the characters. High GCV and PCV were observed for Number of cloves per bulb, diameter of clove, weight of clove, neck thickness of bulb, width of leaf and length of clove.
