The performance of 10 gladiolus cvs with respect to two corm sizes i.e. A-grade (> 5.00 to < 6.00cm) and B-grade (> 2.50 to < 3.50cm) was evaluated. The maximum plant height (111.34 cm) was recorded in cv. Candiman while the minimum (83.62 cm) in Black Beauty which was found to be at par with cv. American Beauty (84.17 cm). A-grade corms resulted in increased plant height (107.50 cm) as compared to B-grade size corms (85.12cm). The flowering was earliest in cv. American Beauty (106.67 day) while the cv. Candiman took maximum days to flower (126.55). A-grade corms took less days to flower (112.64) than B-grade corms (120.09). The maximum number of florets/ spike (16.34) was recorded in cv. Candiman while the cv. Poppy Tears produced minimum (14.25) florets/ spike. A-grade corms produced more number of florets/ spike (16.95) as compared to B-grade corms (13.99). The maximum floret size (8.83cm) was recorded in cv. Candiman whereas cv. Her Majesty produced florets of minimum size (7.10 cm). The floret size was more (8.52 cm) in A-grade corms as compared to B-grade corms (7.22 cm). The data on yield and quality of corms and cormels were also recorded.
