Abstract: An experiment was laid out to evaluate the growth and flowering performance of spray chrysanthemum cultivars in naturally ventilated polyhouse condition. Nine spray chrysanthemum cultivars were evaluated in the experiment. Star Pink recorded maximum plant height (104.29 cm), flower diameter (6.77 cm). Maximum leaf area per plant (1533.68 cm²), number of leaves per stem at harvest (138.25), weight of cut stem (263.39 g), number of flowers per plant (109.67) and number of flowers per square meter (1108.5) were observed in cv. Bronze Spoon. Minimum number of days (95.50) for first flower bud initiation and duration of flowering (45.75 days) was recorded by cv. Indiana. Minimum number of days for 50 per cent flowering and first flower harvest (133.50, 128.50 days), prolonged vase life of (7.50 days) in distilled water was observed in cv. Red Stone.
