Abstract
A study was conducted to assess the combining ability of diverse genotypes of
watermelon in a line x tester mating design at the Vegetable research farm,
Department of Vegetable Science, PAU, Ludhiana, Punjab, India. The 40 F1
hybrids, 10 lines, 4 testers were evaluated in Feb-May, 2019 for yield and
component traits. The analysis of variance indicated significant variability
among all the genotypes for all the traits. The combining ability analysis
revealed that general combining ability effects and specific combining
ability effects were significant for all the traits. The ratio of ?2SCA/
?2GCA indicated the predominance of non-additive gene effects for internode
length, days to appearance of 1st female flower, fruit length, fruit width,
yield/ plant, number of fruits/ plant, average fruit weight, vine length,
TSS and vitamin C. Among the parents, lines WM-10, yellow-2 and Barmer; and
tester KFF 1-1-2 were good general combiner for fruit yield and component
traits. Among the hybrids, W-6-3-3-3-2 ? KFF 1-1-2, WM-20 ? KFF 1-1-2 and
Yellow-2 ? KFF 1-1-2 were good specific combiners for higher TSS content and
good yield.
