Abstract
An experiment entitled “Evaluation of China aster [Callistephuschinensis(L.)Nees] genotypes for growth, yieldandflower quality’’ was carried out during 2017 - 2018 in the Department of Floriculture and Landscape Architecture, College of Horticulture, Bengaluru in randomized complete block design replicated twice. Among the twenty-eight genotypes evaluated, maximum plant height (73.86 cm) was recorded in cv. Arka Violet Cushion, cv.ArkaAadyatook least number of days to first flowering and days to 50% flowering (42.90and 49.60 days, respectively). Maximum flowering duration (35.50 days) was recorded in cv. AAC-1. Maximum flower diameter (7.33 cm) was recorded in Phule Ganesh White. Maximum stalk length (42.19 cm) was recorded in cv. AAC-1. Maximum individual flower weight (7.42 g) was recorded in cv. Phule Ganesh White. Maximum number of flowers per plant (70.80) was recorded in cv. Arka Archana. Flower yield and seed yield on weight basis was highest in cv. AAC-1(216.40 g/plant and 19.21 g/plant, respectively). In variability studies, high GCV and PCV was recorded for all the characters studied except Shelf life. In correlation studies, the number and weight of flowers per plant was significant and positively correlated with plant spread in (North- South) flower diameter and stalk length. In path analysis, plant spread in (North- South) recorded maximum positive direct effect on weight of flowers per plant, followed byplant spread in (East- West) days to 50 per cent flowering and number of primary branches per plant.
