ABSTRACT
The present investigation was carried out with ten cultivars Gladiolus at Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere to evaluate gladiolus cultivars for growth, flowering and corm production under hill zone of Karnataka. Among the cultivars, cv. Red Majesty, Summer Sunshine and Candy Man were early to sprout (5.67, 7.00, 7.00 days respectively), while late in cv. Jester (11.00 days). Per cent sprouting was maximum in cv. Summer Sunshine (95.00%) and minimum in cv. Her Majesty (51.67%). Cultivars Summer Sunshine, Red Ginger, Red Majesty and Green Bay were fairly good with respect to growth attributes such as plant height, number of leaves per plant, leaf length and leaf width, while poor vegetative growth in cultivars Jester and Her Majesty. First floret opening was recorded in cv.Red Majesty (73.87 days), while it was delayed in cv. Jester (91.80 days).Cv. Red Ginger recorded the longest spike length (114.23 cm) and shortest spike length in Her Majesty (70.3 cm). Number of florets per spike was maximum in cv. White Prosperity (18.27). While, minimum incv.Her Majesty (10.80).Spike yield was maximum in cv. Summer Sunshine (116666.33 spikes per hectare) and minimum in cv.Jester (59259.00 spikes per hectare).Vase life was maximum incv. American Beauty (11.67 days).Number of corms per plant was maximum in Summer Sunshine (1.47). Diameter of corm was maximum in cv. Summer Sunshine (7.64 cm) and minimum in cv. Her Majesty (5.39 cm). Maximum yield of corms per hectare in cv. Summer Sunshine (9058.67 kg) and minimum in cv. Her Majesty (921.67g).
