Genetic variability was studied with with 22 gladiolus genotypes (both exotic and indigenous for 19 characters. High genotypic coefficient of variation in number of cormels per plant, weight of corm, propagation coefficient, indicated the presence of sufficient genetic variability for selection in these traits. High heritability and high genetic advance in number of cormels per plant and weight of corms, leaf area, number of floret per spike indicated the presence of additive gene effect in these traits and their amicability for direct selection. Non additive effect (gene) evident in size of floret and days taken to first floret opening. Thus, warresting use of hetrosis in improvement of these characters.
