Table II. Line-mean and single-plant (in parentheses) heritability and genetic correlations with TRL and TDW for 10 phenotypes across nine experiments presented in this study.

ne, Not estimable; TillerN, number of tillers; *, variance component and genetic correlation are statistically different from 0 at P = 0.05; **, variance component and genetic correlation are statistically different from 0 at P = 0.01; ^†, variance component and genetic correlation are not statistically different from 0 at P = 0.10; —, not applicable.
