ABSTRACT
An experiment was conducted with 25 gladiolus genotypes at Main Agricultural Research Station, Floriculture unit, Dharwad. The minimum days required for spike initiation (60.60 days) and first floret opening (66.27 days) were observed in genotype White Siphon. Maximum plant height (64.48 and 78.18 cm at 30 and 60 DAP, respectively) was recorded in genotype Pacifica and spike length (97.30 cm) in Red Ginger, whereas maximum rachis length (64.60 cm) was recorded in White Prosperity. Maximum number of florets per spike (14.00) and vase life (9.80 days) were recorded in Jester genotype. Highest corm weight with respect to heritability highest percent was recorded in rachis length (86.90) and highest percent GAM in number of leaves at 30 DAP (163.99) followed by corm diameter (124.00) and least in days for first floret to show colour (6.60).
