False black chaff in wheats
carrying the stem rust resistance gene Sr2
There have been many recent enquiries concerning the appearance
of black discoloration on glumes and stems of certain wheat

the outer glumes, to deep black pigmentation on glumes and
stems, especially in the stem region just below the node. These
symptoms may indicate one of several possible causes, including
disease or physiological disorder.
