These lines are the same 40 lines (except D_AS34) used by Andersen et al.[36].
Flint- and dent lines are denoted by F_ and D_ prefixes, respectively.
PHT: plant height (cm); DTS: days to silking; DMC: dry matter content of stover; DMY: dry matter yield of stover (tons per hectare)
LSD5: least significant difference at 5% level between lines
CI: confidence interval
*, ** significant at 5% and 1% level, respectively.
