Covered and naked barleys from the Himalaya : 1. Evidence of multivariate differences between the two types.

Both reciprocal averaging and discriminant analysis confirm visual impressions that covered and naked barleys from several areas in the Himalaya differ significantly from each other in a multivariate way. Discriminant analysis also suggests similar differences between the 'occidental' and 'oriental' barleys of Takahashi (1955). Either distinction has implications for our understanding of barley phylogeny and evolution.
