Multivariate analysis of divergence among 25 varieties of gladiolus for 16 developmental characters led to their grouping into five clusters. Based on cluster means, characters like days to initial flowering, leaf area, days for last floret opening, number of corms and cormels produced per plant and propagation coefficient were the major factors for differentiation amoung 25 genotypes. The intercluster D2 values ranged from 11.417 to 84.953 suggesting very little domestication in this crop.

25 varieties of gladiolus were used to study the variability for 16 characters. Heritability estimates and genetic advance were high for the characters like number of cormels produced per plant, weight of corms and cormels and propagation coefficient, leaf area, rachis length, number of seeds per capsule showing the additive gene effect.
