Sixty longmelon progenies/genotypes of three crosses viz., LM 3 × AS, LM 9 × AS, LM 15 × AS along with its parents and check variety was evaluated in F3 generation for quantitative and qualitative traits at College of Horticulture, Kolar, Karnataka. Analysis of variance revealed significant high amount of variability among the progenies for most of the characters studied. The ranges of mean values revealed sufficient variation for all the traits under study. The phenotypic coefficient of variation (PCV) value was found to be higher than the genotypic coefficient of variation value (GCV) and narrow differences was observed between PCV and GCV values for most of the characters under studied, indicates less environmental influence. High estimates of heritability coupled with high values of genetic advance over mean (GAM) were observed for characters viz., days to 50% germination, pericarp thickness, duration of harvesting, node at which first male flower anthesis, node at which first female flower anthesis, sex ratio, fruit length, average fruit weight, fruit yield and shelf life. This indicates the characters were governed by additive genes; further crop improvement can be done through simple selection for these characters.
