Assessment of genotypic and phenotypic correlation for flower yield in F4 population of China aster [Callistephus chinensis L. (Nees.)]

Abstract

This study was mainly conducted to assess the correlation in China aster [Callistephus chinensis L. (Nees.)] flower crop was conducted during the year 2018-2019 at Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi. Treatment details having forty lines from F4 population of two crosses viz., AAC-1 × Arka Poornima and Arka Kamini × P G Purple were assessed for 13 quantitative and qualitative traits for different parameters with yield components and their direct and indirect correlation on flower yield. Genotypic correlation for flower yield is positively associated with number of branches, plant height, number of flowers per plant, leaf area and plant spread and negatively with the flower diameter indicating the possibility of simultaneous selection for these traits to improve the yield.
