FAWTH2003

This hybrid is from the first generation of FAW-tolerant maize hybrids out of CIMMYT's eastern Africa product pipeline 1A (EA-PP1A). This pipeline primarily focuses on developing intermediate maturing, 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 eastern Africa.   General Information
  Adaptation/Agroecological zone 1000 - 1600 masl
  Type of product Three-way cross hybrid
  Year first announced 2020
     
  Grain Characteristics
  Grain color White
  Grain texture Semi dent
     
      Biotic Stress Performance
