Abstract

A field experiment to evaluate twenty five Hybrid Tea rose varieties was conducted at an experimental field of Department of Floriculture and Landscape Architecture, College of Horticulture, Bengaluru from October 2017 to March 2018. Results revealed that there was significant variations among the varieties for growth, flowering and yield characters. Among the varieties, maximum plant height (118.50 cm) was recorded in var. Claire Chazal. The maximum stem girth, chlorophyll content and individual leaf area were recorded in var. Claire Chazal (10.60 mm, 58.90 SPAD value and 25.07 cm2, respectively). Among the varieties, var. Chantre took least number of days for bud initiation, days from bud initiation to tight bud stage and days from bud initiation to full bloom stage (36.00, 13.20 and 15.00 days, respectively). Maximum number of cut flowers per plant and per m2 (20.00 and 83.00, respectively) were recorded in var. Cherry Parfait. Maximum stalk length (55.40 cm) was obtained in var. Claire Chazal. Among the varieties, the maximum vase life (11.50 days,) was recorded in var. Eterna.
