Heterosis for growth and yield traits in annual chrysanthemum (Glebionis coronaria [L.] Cass. ex Spach.)

Abstract

A line x tester analysis was carried out involving five lines (White Majestine, AACS-3, Sarpan White, Sarpan Yellow and Garden Aids) and three testers (Dharwad White, Dharwad Yellow and Bagalkot Local) were analyzed for heterosis for 8 characters in annual chrysanthemum. The experiment was conducted at the Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2020-21. Sarpan White × Bagalkot Local and Sarpan Yellow × Dharwad White exhibited Significant negative heterosis for plant height and 50 per cent flowering, respectively. White Majestine × Bagalkot Local and Garden Aids × Bagalkot Local reported significant heterosis for flower yield per plant and seed yield per plant, respectively.
