Abstract:
Seven genotypes of China aster [Callistephus chinensis (L.) Ness] were evaluated for genotypic correlation coefficient between flower yield and 28 quantitative traits, to understand the association between these characters and their relative contribution to flower yield. The present investigation was carried out during the year 2017-18 at College of Horticulture, Dr. Y.S.R Horticultural University, Anantharajupeta, Y.S.R. Kadapa Dist. of Andhra Pradesh. The experiment was laid out in randomized block design with four replications under 50 per cent shade net condition. The aim was to bring about rational improvement in China aster. Significant positive correlation for the flower yield ha-1 with number of leaves plant-1 (0.897), number of branches plant-1 (0.893), plant spread (0.910), LAI (0.830), protein content in flowers (0.804), number of flowers plant-1 (0.944), weight of flowers plant-1 (0.999) and yield ha-1 (0.972) and negative correlation with days to first flower opening after flower initiation (-0.821). These traits may serve as effective selection parameters for breeding in China aster for improvement of the yield.
