Source of variation (SV), degree of freedom (DF), stem height (SH), stem diameter (SD), leaf area (LA), leaf number (LN), root (RDB), stem (SDB), leaf (LDB) and total (TDB) dry biomasses, general combining ability (GCA), specific combining ability (SCA), sum of squares of the general combining ability (SSgca), sum of squares of the specific combining ability (SSsca) and mean heritability (h2). P<0.05 (*) and two (**) asterisks indicate significance by F test at 5 and 1% probability, respectively.
