Narrative
TZEEI 20 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 20 silks at 60 days and has plant height of 123 cm. It has a Striga emergence count of 6 plants per plot (0.75 m x 5 m) and Striga damage syndrome rating of 4 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 3236 kg/ha under Striga-free conditions and 3112 kg/ha under artificial infestation with 5,000 germinable seed of S. hermonthica. TZEEI 20 has flint grain texture.
