Table II. Variance partitioning within and between cultivars for traits measured as part of the controlled environment experiment and those used for both experiments (i.e. Ci* and Rd)

Variance attributed to cultivar provides an upper limit estimate of the contribution of genetics to observed trait variability. Trait abbreviations are as in Table II. Min and Max are the minimum and maximum trait values. The variance components were estimated by partitioning variance within and between cultivars with restricted maximum likelihood (REML).
