Genotypic and Phenotypic Variability in Gladiolus

Sixty varieties of gladiolus were used to study the genotypic variability for 20 characters. Heritability estimates and genetic advance were higher for the characters like number of carmels produced per plant. Heritability in number of shoots per plant and number of cormels produced per plant attributed to additive gene effects. Thus selection based on these characters will be very effective for the improvement of this crop.
