CAH204

CAH204 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-heat conditions, and has tolerance to TLB, MSR and FSR.   General Information   Target Region South Asia   Adaptation/Agroecological zone Tropical lowlands
