Abstract:
Sixteen intervarietal hybrids of Mangalore melon (Cucumis melo var. acidulous) were developed and evaluated at college of horticulture, Sirsi (Karnataka) to study the genetic variability and correlation present among the hybrids. Results revealed that significant genetic variability present among hybrids for almost all traits. A high range of variation, high PCV, GCV and high heritability observed for all the traits studied. However, high heritability coupled with high genetic advance was recorded for average fruit weight, vine length, days to first harvest, fruit diameter and fruit length it indicates less environmental influence, broader genetic base and also it depicts presence of additive gene action. Rest of the traits showed high heritability with low to moderate genetic advance indicates presence of dominant gene action. Further correlation study reveals that at genotypic level, fruit yield per plant had a highly significant and positive correlation with vine length, number of primary branches, number of fruits per plant, fruit length, fruit width, fruit diameter, average fruit weight, flesh thickness and seed cavity length and at phenotypic level, fruit yield per plant had a highly significant and positive correlation with vine length, number of primary branches, number of fruits per vine, fruit length, fruit diameter, average fruit weight, flesh thickness and seed cavity length.
