Methods for increasing yield of fermentable sugars from plant stover are provided. The methods include using plants homozygous for two brown midrib mutations, bm1 and bm3. The methods also include using plants homozygous for a mutation in a gene that results in reduced cinnamyl alcohol dehydrogenase activity, and a mutation in a gene that results in reduced 5 -hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity. The methods also include using transgenic plants that have reduced cinnamyl alcohol dehydrogenase activity and reduced 5 -hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity in comparison with wild-type plants.

We claim: 1. A method of increasing yield of fermentable sugars in a plant stover, the method comprising:producing a plant stover from a plant comprising a homozygous bm1 mutation and a homozygous bm3 mutation; andtreating the plant stover with a cellulolytic enzyme to produce a fermentable sugar;wherein a yield of the fermentable sugar obtained from the plant stover thus produced is higher than a corresponding yield obtained from a plant stover produced from a plant that does not contain the homozygous bm1 mutation and the homozygous bm3 mutation.
