Genetics of flower colour in China aster (Callistephus chinensis (L.) Nees)

Summary The genetics of flower colours violet, blue, deep pink, pink, light pink, creamy white and white was investigated in 17 cross combinations involving 10 parents in China aster (Callistephus chinensis (L.) Nees). Violet was dominant over all other colours; blue was dominant over creamy white; deep pink was dominant over pink and white, but incompletely dominant over light pink and pink was dominant over light pink and white. Four genes C, R, B and P were found to govern these different flower colours. The gene P had a dominant allele P^D and a recessive allele p.Contribution No. 146/88 of the Indian Institute of Horticultural Research, Bangalore 56080, India.
