HP1306

CIMMYT's southern Africa product pipeline 3 (SA-PP3) focuses on developing nutritious maize varieties (biofortified with PVA and/or High Zn), orange and white grain, high-yielding maize hybrids that are drought tolerant, NUE, resistant to GLS, TLB, ear rots, and MSV, and are suitable for food use in tropical rainfed dry/wet mid-altitude areas in southern Africa.   General Information

Ear height 88 cm   Nicking 1.0 Days
Plant height 193 cm      
Root lodging 6.1%   Comments
Stalk lodging 1.6%   Product information is based on data from the CIMMYT Southern Africa Maize Regional On-Station 2017 Trials.
