TAILIEUCHUNG - Studies on genetic variability, heritability and genetic advance in F2 segregating population of Cross Arka Archana × AAC-1 in China Aster [Callistephus chinensis (L.) Nees]

The present study was conducted to evaluate genetic variability in F2 population of cross Arka Archana × AAC-1 in China aster at the College of Horticulture, Mudigere during 2017-18. The phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits. High (>20 %) phenotypic coefficient of variation (PCV) and genotypic coefficient of variation(GCV) was recorded for number of branches per plant, plant spread East-West, number of flowers per plant, disc diameter, 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, number of branches per plant, plant spread North-South and East-West, flower diameter, disc diameter, flower stalk length and flower yield per plant and indicated that the high heritability is due to additive gene effects which can be utilized for further crop improvement programme. | Studies on genetic variability, heritability and genetic advance in F2 segregating population of Cross Arka Archana × AAC-1 in China Aster [Callistephus chinensis (L.)
