CAH1511

­

CAH1511 is an intermediate-maturing maize hybrid bred for the tropical lowlands of South Asia. This high-yielding, yellow-kernel maize hybrid performs well under drought and drought-plus-waterlogging conditions, and has tolerance to TLB, FSR and BLSB.   General Information
  Target Region South Asia
  Adaptation/Agroecological zone Tropical Lowland
  Type of product Single-cross hybrid
  Year first announced 2015
     
      Kernel Characteristics
