The newly available CIMMYT maize hybrids, CIM20LAPP1C-9, CIM20LAPP1C-10, CIM20LAPP1A-11 and CIM20LAPP1A-12, were identified through rigorous trialing and a stage-gate advancement process which culminated in the 2020 and 2021 CIMMYT Latin America Stage 4 and Stage 5 Trials. The products were found to meet the stringent performance criteria for CIMMYT’s LA-PP1A and LA-PP1C breeding pipelines. While there is variation between different products coming from the same pipeline, the LA-PP1A and LA-PP1C pipelines are designed around the target product profiles described below:
