Twenty five varieties (11 hybrids and 14 varieties as the respective parents of these hybrids) 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 carmels and propagation coefficient, leaf area, rachis length and number of seeds per capsule showing additive gene effects. Thus the selection of the basis of these characters will be very effective for the improvement of this crop.
