Combining ability analysis for flowering and quality parameter in annual chrysanthemum (Glebionis coronaria [L.] Cass. ex Spach.)

Abstract

The study of general and specific combining ability of parents and crosses to identify superior parents and crosses respectively. 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) to obtain fifteen crosses. The experiment was conducted at the Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2020-21. The parent White Majestine followed by Sarpan White were good general combiners for the majority of the traits. The cross combination Sarpan White x Dharwad White, White Majestine x Dharwad White, Garden Aids × Bagalkot Local, White Majestine × Dharwad Yellow and AACS-3 × Dharwad White are the best specific combining ability for various trait.
