The experimental material consisting of 18 lines and four standard checks were raised in RBD in three replications. Significant differences between the test entries were observed for all the traits. Twenty-two genotypes were grouped into VII clusters on the basis of observed distance among genotypes within a cluster as compared to genotypes in another cluster. Cluster III contains maximum number (seven) of genotypes. Cluster I had highest grain yield per plant, 100-grain weight, harvest index and tryptophan content while cluster VII had lowest anthesis silking interval and highest oil and lysine content and cluster V had maximum starch content. The better performing genotypes from clusters I, II and III were identified for all the traits. Therefore, F1 derived from such diverse crosses is expected to show high yield.

Valan kakri is an underexploited vegetable and has great potential for genetic improvement through systematic approach. In this study, variability parameters were evaluated in 30 genotypes of Valan kakri collected from different villages across Udaipur during September 2019 and morphological studies were done at Rajasthan College of Agriculture, Udaipur. The genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were highest for fruit length (34.48%, 35.43%) followed by fruit weight (61.64 % and 62.04). Estimates for heritability (Broad sense) ranged from 69.70% for seed cavity breadth to 99.24% for acidity of fruit. Traits like fruit length, fruit weight, seed cavity length, acidity of fruit, ascorbic acid content had high GCV, PCV and heritability along with high genetic advance as percentage of mean. Therefore, selection can be effective for these traits in crop improvement programme.
