Abstract:
A line x tester analysis was carried out involving five lines (Namdhari Pink, Namdhari White, Miraj Local, Arka Poornima and P.G. Purple) and two testers (Arka Kamini and AAC-1) were analysed for heterosis for 13 economic traits in China aster. The experiment was conducted at Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2019-20. Miraj Local x AAC-1 and P.G. Purple x Arka Kamini exhibited significant positive heterosis for majority of the traits including yield parameters. Namdhari Pink x Arka Kamini and Arka Poornima x AAC-1 reported significant negative heterosis for days to first flowering and days to 50 per cent flowering.
