Abstract
The present experiment entitled, “Evaluation of rose (Rosa hybrida L.) cultivars for landscape use” was carried out at the Research Farm, Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana during the year 2009-2011. The experiment comprised of 30 floribunda and 20 miniature cultivars. The maximum plant height (53.67 cm) was observed in cultivar ‘Banjaran’ and ‘Torch of Liberty’ (30.00 cm) in floribunda and miniature cultivars respectively. The maximum plant spread (90.83 cm) was recorded in floribunda cultivar ‘Brown velvet’. The floribunda cultivars ‘Summer Snow’, ‘Ahalya’ and miniature cultivars ‘Red Flush’ and ‘Red Ace’ were observed to be thornless. The foliage glossiness was observed in four floribunda and two miniature rose cultivars. Flower size was observed to be maximum in ‘Charleston’ (8.37 cm) and ‘Black Jade’ (5.23 cm) in floribunda and miniature cultivars respectively. Flower colour of the cultivars evaluated varied from Red, Purple, Yellow to Orange group. Maximum duration of flowering (141.33 days) was observed in ‘Brown velvet’ cultivar of floribunda. In case of miniature cultivars maximum duration of flowering (131.33 days) was observed in cultivar ‘My Valentine’. Maximum number of petals per flower was recorded in cultivars ‘Arunima’ (66) and ‘Rosy’ (100) in floribunda and miniature rose cultivars respectively. Seed setting was observed in seven floribunda rose cultivars and seven miniature rose cultivars.
