This variety also recorded maximum floret size (10.89 cm). Number of corms per plant and weight of corms per plant were found maximum in Spic and Span (1.44 and 39.56 g), respectively. Amsterdam exhibited maximum number of cormels per plant (29.33) and weight of cormels per plant (4.35 g). Average corm diameter was recorded maximum in Peter Pears (4.41 cm) and minimum in Spic and Span (4.17 cm).
