The brown spot and powdery mildew disease incidence and severity were assessed in ten tillers of ten plants per plot, which were sampled randomly at the five different plant GS 22 (main shoot and 2 tillers), 31 (swelling 1st node detectable), 39 (Flag leaf ligule just visible), 45 (Full-boot, boot above ligule of 2nd last leaf) and 56 (60% of spikes visible).
Coleoptile A tubular extension of the sheath above the point of insertion of the hyperphyll (usually called a ligule, sometimes called an ocrea).
The leaf blades are broad, between 3 and 5 cm wide, and the ligule is blunt and pubescent.

This renewed interest in the genus has stimulated investigation into other morphological features, including leaf anatomy (presence or absence of fibers; intrastelar canals), variation in ligule and labium characters (R.
