Symptoms include brown to black discoloration of the glume extending from slight longitudinal marks to large black areas covering most of the glume surface. In severe expression, the stem area below the last node may become distinctly brown to black discoloured. The trait appears post-flowering with a peak at late milk-soft dough stage.

In 2009 the Toronto International Data Release Workshop agreed on a policy statement about prepublication data sharing. Accordingly, the data producers are making many of the datasets in T3 available prior to publication of a global analysis. Guidelines for appropriate sharing of these data are given in the excerpt from the Toronto Statement.

I agree to the Data Usage Policy as specified in Toronto Statement.
