CZH142011

CZH142011 is a late-maturing, white-grain, high-yielding, drought-tolerant maize hybrid that is resistant to rust, GLS, TLB, Ear rots, and MSV, bred for food use in tropical, rainfed, dry/wet mid-altitude and transition ecologies in southern Africa and similar agroecologies.     General Information
  Target region Southern Africa
  Adaptation/Agroecological zone 400-1800 masl
  Type of product Single-cross hybrid
  Year first announced 2016
     
      Grain Characteristics
Grain Yield   Grain color White
