Abstract: China aster [Callistephus chinensis (Linn.) Ness] isan important commercial ornamental annual flower plant.Seven genotypes of China aster were chosen to evaluate the growth, flowering and seed production and the field experiment was carried out in new alluvial zone at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Vishwavidyalaya, Mohanpur, Nadia, West Bengal, India during Rabi seasons of 2016-17 to 2017-18.Seeds of China aster were raised in individual plots following standard agronomic practices and intercultural operations. Field performance of seven genotypes of China aster was observed for different parameters like plant height, number of flowers plant-1, flower diameter, days to flower initiation, days to 50% flowering and seed yield plant-1. Highest seed yield plant-1 was recorded in Arka Poornima (3.50g, 3.40 g, and 3.45 g in 1st year, 2nd year and pooled respectively) whereas lowest seed yield plant-1 was recorded in Arka Aadya (1.93g in 1st year, 1.80 g in 2nd year and 1.87 g in pooled respectively).
