An experiment was conducted in polyhouse conditions to evaluate 14 cultivars of chrysanthemum including five standard types and nine spray types. Among standard types maximum plant height (115.79 cm), flower diameter (14.08 cm) and flower stalk length (96.72 cm), and minimum number of days for 50 per cent flowering (122.25) was recorded in cv. Snow Ball, Maximum number of primary branches per plant (5.97) in cv. Star White. Chandrama recorded maximum internodal length (4.67 cm) and maximum

Star Pink recorded maximum plant height (104.29 cm), flower diameter (6.77 cm) and flower stalk girth (6.81 mm). Terry showed (6.48) maximum number of primary branches per plant. The cv. Yellow Spoon (94.63 cm) recorded maximum stalk length. Maximum inter nodal length (3.56 cm), minimum number of days to 50 per cent flowering (133.50) was noted in cv. Red Stone. Bronze spoon recorded maximum (0.76) leaf area index, more number of flowers per plant (109.67) and number of flowers per square metre (1108.50).
