Narrative

TZEI 9 is tropically adapted early maturing, yellow endosperm maize (Zea mays L.) inbred line with moderate levels of resistance to the parasitic weed, Striga hermonthica (Del.) Benth. The inbred line has good levels of resistance to the maize streak virus (MSV), Puccinia polysora Underw, and Bipolaris maydis (Nisikado and Miyake) Shoemaker. TZEI 9 sheds pollen at 52days, silks at 54 days and has anthesis-silking interval of 2 days; plant height of 106 cm and ear height of 50 cm. It has a Striga emergence count of 34 plants per plot (0.75 cm 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 774 kg/ha under Striga-free conditions and 626 kg/ha under artificial infestation with 5,000 germinable seed of S. hermonthica. TZEI 9 is susceptible to drought and has flint grain type.
