Abstract: An investigation on “Genetic studies in F3 population of China aster [Callistephus chinensis (L.) Nees.]” was carried out during 2017-2018 at department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi with the aim to study the genetic variability in two F3 population obtained from the crosses viz., AAC-1 × Arka Poornima and Arka Kamini × P G Purple. The analysis of variance revealed highly significant difference among the genotypes for all the characters studied indicating the higher magnitude of variability in the genotypes. The estimates of GCV and PCV values were higher with high heritability and high GAM for plant height, plant spread in North - South, East - West and flower stalk length in Arka Kamini × P G Purple and for number of branches and leaf area in AAC-1 × Arka Poornima were found high indicating the possible role of additive gene action in their genetic control. Yield per plant had positive and highly significant correlation with number of flowers per plant, individual flower weight and flower diameter in both the F3 segregating population of China aster, suggesting the possibility of simultaneous selection for these characters. Path analysis revealed that duration of flowering, number of flowers per plant and individual flower weight had high direct effects, which indicated the possibility of increasing flower yield by selecting the F3 population for these characters directly in both the crosses. Expression of flower colour indicated ratio of 16:5:4 (Deep pink: Light pink: White) in AAC-1 × Arka Poornima and 19:5:1 (Purple: Pink: Light pink) in Arka Kamini × P G Purple. The F3 population of AAC-1 × Arka Poornima had performed better for yield traits compared to Arka Kamini × P G Purple. In the cross AAC-1 × Arka Poornima the lines like Line 42, Line 196, Line 161 and in the cross Arka Kamini × P G Purple lines like Line 10, Line 74 and Line 37 were found superior with respect to flower yield and quality parameters.
