Abstract

A study on the performance of elite Dutch rose varieties under naturally ventilated polyhouse for Northern dry zone of Karnataka was carried out during 2022-23 at the experimental block, Department of Floriculture and Landscape Architecture, College of Horticulture, University of Horticultural Sciences, Bagalkot. The experiment was laid out in Randomized Block Design (RBD) with seven varieties and three replications. The varieties were Top Secret, Jumilia, Solar, Revival, Rock Star, Arka Pride and Arka Ivory. Various growth, flowering and yield parameters were recorded during experimental period (September 2022 – September 2023). Among all the varieties studied, the variety Jumilia was superior with respect to plant height (81.22 cm), plant spread (E -W: 46.19 cm and N -S: 45.24 cm), number of branches per plant (4.52), leaf area per plant (2893.28 cm2), stem girth (1.43 cm), days taken for first flower bud initiation (35.67 days), days taken for first flowering (60.00 days), number of flowers per plant (23.98) and number of flower stalks per m2 (216.79).
