Distribution of DBH (upper panel) and wood basic density (lower panel) trait values at four years of age in theE. grandis(blue) andE. urophylla(black) backcross families. The E. grandis backcross family had slightly higher average DBH than the E. urophylla backcross family (15.4 vs. 13.0 cm, Table 1), while the E. urophylla backcross family had higher average wood basic density (410 vs. 305 kg/m3).
