Abstract
Forty four genotypes of water melon (Citrullus lanatus) was evaluated for genetic variability, heritability and genetic advance for yield and its contributing characters in watermelon during Summer 2019. Analysis of variance showed significant variation for all the studied characters, indicating presence of sufficient variability in the material. Widest range of variation was observed for fruit girth, fruit length, average fruit weight, fruit yield and fruit diameter. Maximum genotypic and phenotypic coefficient of variation (GCV and PCV) was observed for seed size, average fruit weight and vine length followed by total soluble sugar and first female flowering node. High magnitude of heritability was exhibited in vine length (0.98) and average fruit weight (0.98) followed by seed size (0.97), total soluble sugar (0.91), first female flowering node (0.87), fruit length (0.86) and fruit diameter (0.74). The maximum genetic advance as percent of mean was observed for seed size (85.1), vine length (84.3), average fruit weight (74.9), total soluble sugar (34.8) and first female flowering node (28.4). High heritability coupled with high genetic advanced depicted in characters viz., seed size, average fruit weight, total soluble sugar, fruit length, fruit diameter, vine length and first female flowering node indicating that the heritability is most likely due to additive gene effects and thus the chances of fixing by selection.
