Table 6.
Estimated broad sense heritability (Eq. 3) of axial and lateral root number (NoAx and NoLat, respectively) and plant vigor traits using variance components 3 weeks after shoot emergence; heritability based on means (n = 4) of 14 varieties was calculated separately for low (1.3 g cm-3), moderate (1.45 g cm-3), and high soil bulk density (1.6 g cm-3).
