Differentiating Two Popular Cultivars of Large Cardamom (Amomum subulatum Roxb.) using a Statistical Method

Priya P Menon1*, VV Radhakrishnan2

The variability in large cardamom (Amomum subulatum) germplasm was studied by the application of multivariate methods such as Hotelling’s T2 statistic and discriminant function analysis. Data on variables such as girth of the clump, number of bearing tillers, number of spikes per clump, number of capsules per spike, capsule length, capsule diameter and capsule weight were recorded in 40 accessions belonging to two cultivars of large cardamom namely Ramsey and Sawney. Hotelling’s T2 test revealed that there is significant difference between the cultivars with respect to the characters studied. Discriminant function analysis brought about a discriminant function to distinguish between the two cultivars of large cardamom.
