Narrative

TZEEI 21 is extra-early maturing, white endosperm maize (Zea mays L.) inbred line with moderate levels of resistance to the parasitic witchweed, Striga hermonthica (Del.) Benth. The inbred line also has good levels of resistance to maize streak virus (MSV), tropical lowland rust (incited by Puccinia polysora Underw.) and blight [caused by Bipolaris maydis (Nisikado and Miyake) Shoemaker]. TZEEI 21 silks at 62 days and has plant height of 113 cm. It has a Striga emergence count of 3 plants per plot (0.75 m x 5 m) and Striga damage syndrome rating of 5 on a scale of 1-9 where 1=little or no damage and 9= severe damage due to S. hermonthica. It produced a grain yield of 2260 kg/ha under Striga-free conditions and 1506 kg/ha under artificial infestation with 5,000 germinable seed of S. hermonthica. TZEEI 21 has flint grain texture.
