Figure 2From: Selection and phenotypic characterization of a core collection of Brachypodium distachyon inbred linesPrincipal component analysis of NIR spectra from ground stems from the core collection of lines grown outside without controlled vernalization. Samples from at least three plants per line were tested; each data point represents a single individual. Note the separation of groups along the first two principal components, PC 1 and PC 2. The percent variance explained by PC 1 and PC 2 is indicated.Back to article page
