Principal component biplot displaying variation in cell wall composition and conversion efficiency harbored within the mapping population. Red dots are genotype mean scores. Trait names designated with ‘[1]’ were scored after the second growth season of the population, while those designated with ‘[2]’ were scored after the third growth season. Vectors represent traits, with the angle between a vectors and the principal component axis proportional to the contribution of the corresponding trait to those principal components. The length of vectors is proportional to the variance observed for the corresponding trait and the angle between vectors is proportional to the correlation among characters
