| This hybrid is from the first generation of MLN-tolerant maize hybrids to come out of CIMMYT's eastern Africa product pipeline 1A (EA-PP1B). This pipeline primarily focuses on developing high-yielding, early maturing maize varieties with white grain, drought tolerance, NUE, and resistance to GLS, TLB, MSV, ear rots, and MLN, that are suitable for food use in tropical, rainfed, dry, mid-altitude areas in eastern Africa and similar agroecologies. |
