Abstract

The present study was conducted to evaluate genetic variability in F3 population of cross AAC-1 X Arka Poornima in China aster at the Kittur Rani Channamma College of Horticulture, Arabhavi during 2022-23. High (>20 %) phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was recorded for number of branches per plant, Individual flower weight and flower yield per plant. High heritability (>60 %) coupled with high genetic advance as per cent over mean (>20 %) were recorded for plant height, plant spread (East-West), plant spread (North-South), number of branches per plant, Stem girth, number of flowers per plant, duration of flowering, individual flower weight and flower yield indicated that the high heritability is due to additive gene effects which can be utilized for further crop improvement programme.
