Barley proteins: relation to malt quality in a context of climate change and need of sustainability – The new challenge.

The article discusses diversity of barley protein composition for the same total nitrogen content with a 2 up to 3-fold factor depending the protein fraction. This major result demonstrates that the barley variety is the most significant factor triggering different protein compositions. But the different clusters gather independently some 6 row winter lines can be with some 2 row spring lines.
