It was observed that genotypic coefficient of variation (GCV) was lower than phenotypic coefficient of variation (PCV) for all the traits under study. The highest value of genotypic and phenotypic coefficient of variation was recorded for the character number of ray florets (57.21), (57.57) respectively. The estimates of GCV and PCV were of high magnitude in number of branches per plant, number of ray florets, number of flowers per plant, weight of 10 flowers, yield of flowers per plant, yield of flowers per plot and yield of flowers per hectare. The estimate of heritability ranged between Plant spread in N-S direction (58.60%) to Number of ray florets (98.80%). High estimate of heritability (98.80%) was recorded for Number of ray florets. The range of genetic advance was from 0.38 to 12067.69. The character, Yield of flowers per hectare exhibited highest genetic advance (12067.69%), followed by Yield of flowers per plant (203.40%), followed by Yield of flowers per plot (150.69%). The lowest value of genetic advance was reported for character disc diameter (0.38%). Therefore, these characters should be given top priority during selection breeding in annual Chrysanthemum.
