Abstract:

An experiment was carried out on study of genetic variability in 30 genotypes of greater yam at Department of Horticulture, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during kharif season 2018-19. Observations were recorded on 22 growth and quality characters viz., days to emergence, first leaf emergence, number of leaves (30 DAE), number of sprouts per seedtuber, vine length at 45 DAE, internode length, vine length at harvest, leaf width, petiole length, tuber length, diameter of tuber, number of tuber per vine, weight of tuber, stem girth, tuber yield per vine, starch, ascorbic acid, moisture, TSS, total sugar, total Phenol, dry matter. The analysis of variance indicated that the mean sum of square due to genotypes were highly significant for all the characters suggesting the presence of good amount of variability in material studied. The estimates of GCV and PCV, heritability, genetic advance & genetic gain were higher for evaluated traits.
