|Abstract:||The investigation on “Divergence and character association studies in Snake gourd (Trichosanthes cucumerina L.)” was conducted in the field of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi. Thirty genotypes collected from NBPGR, New Delhi were evaluated in randomized block design with two replications during kharif 2017. The analysis of variance revealed highly significant (both at P=0.01 and P=0.05) difference among the genotypes for all the characters studied indicating the higher magnitude of variability in the germplasm. The high genetic advance over mean coupled with high heritability was observed for characters like number of primary branches per plant, vine length, number of nodes per vine, inter nodal length, node at which first female flower appears, number of fruits per plant, average fruit weight, fruit length, flesh thickness, number of seeds per fruit, fruit fly infestation, downy mildew incidence and yield per plant. Thus, these characters were under additive gene effect and could be improved by simple selection schemes. The results on correlation and path analysis revealed high positive and significant association of fruit yield per vine with characters Viz., vine length, fruit length, number of fruits per vine, average fruit weight, flesh thickness, protein and these characters also had high direct and indirect effect on fruit yield per vine. Hence direct selection for these traits would be more useful in the improvement of yield per vine. Based on Mahalonobi’s D2 analysis, 30 genotypes were grouped into 7 clusters. The cluster I showed maximum intra-cluster distance (D2 = 912.37), whereas, the maximum inter cluster distance was observed between cluster II and VII (D2 =13761.92). Among the 22 characters studied, number of seeds per fruit (39.77%) contributing maximum to genetic diversity. Top five genotypes viz., ASNG -7, ASNG- 23, ASNG-24, ASNG-8 and ASNG-16 were recorded high fruit yield per vine Therefore, these genotypes can be further assessed for their stability|
