Abstract: Gladiolus cultivars have been arisen as a result of extensive hybridization and selection, which has occupied one of the most important commercial horticultural crops for the floriculture trade. National Botanical Research Institute, Rana Pratap Marg, Lucknow is very rich with germplasm collection both exotic and in bred cultivars. Under conventional breeding programme 33 cultivars of gladiolus were selected on the basis of desirable vegetative, floral and palynological characters. It was interesting to note that varietal differences were found in number of flower per spike. A wide range of variability could also be selected in spike length among the cultivars. Colour of all cultivars have been matched and identified. It was interesting to note that about 88% of the cultivars had pollen grain fertility above 50% among the presently tested cultivars. Maximum cultivars have pollen fertility between 80-90%. Pollen grains were uniform but size differences were recorded among the cultivars.
