Abstract
An experiment was conducted at Department of Floriculture and Landscape Architecture, Kittur Rani Chennamma College of Horticulture, Arabhavi during the year 2015-16. Thirteen rose varieties were used for the varietal evaluation study and the variety Charisma was used to know the effect of VAM and rooting hormone on the propagation by cuttings.
Among the thirteen varieties studied, maximum plant height (50.00 cm), stem girth (2.23 cm), flower weight (1.70 g), average flower yield per plant per month (37.66 g), average flower yield per m2 (43.7 g), flower yield per hectare (4.5 t/ha) were recorded in Palm-de-Mour. The variety Charisma produced maximum number of branches (14.99), plant spread in East-West (37.49 cm) and North-South (37..00 cm) directions, minimum infestation of black spot disease (15.92%) and took minimum number of days for initiation of flower bud to bloom (3.53 days) and days to 50% flowering (52.22 days). Maximum number of leaves (241.33) were observed in Aishwarya. Maximum leaf area (917.77 cm2) and minimum infestation of thrips (8.22%) were recorded in variety Five Plus. More average number of flowers per plant per month (26.95) and overall acceptability (4.67) were recorded in variety Vanesa.
Among the rooting hormones and VAM fungus species studied on rooting of cuttings of cv. Charisma, there was significant difference in greening and sprouting percentage, highest percentage was observed in inoculation with VAM fungus Sclerocystis dussi (88.89%). But there was no significant difference in rooting percentage among the treatments.
