Narrative
TZEEI 2 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 2 silks at 55 days and has plant height of 116 cm. It has a Striga emergence count of 34 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 845 kg/ha under Striga-free conditions and 743 kg/ha under artificial infestation with 500,000 germinable seed of S. hermonthica. TZEEI- 2 has flint grain texture.
