Zinc deficiency is one of the major causes of malnutrition in the communities due to the consumption of zinc-deficient staple food. With accessibility and affordability, biofortification is an agricultural intervention beneficial for all the stakeholders involved as any actor. A total of 16 exotic zinc biofortified maize hybrids developed at different maize research stations of CIMMYT got introduced and evaluated across three separate locations in major maize growing areas of Punjab and Khyber Pakhtunkhwa (KP), i.e., Faisalabad, Sahiwal, and Nowshera. The decision to introduce exotic zincenriched maize germplasm in Pakistan, in collaboration with CIMMYT, Mexico, came from the findings of a related research work--evaluation of diverse indigenous maize germplasm; however, none of the entry qualified for suggested biofortification standard, i.e., 33 mg/kg zinc. Introducing exotic material depends upon its yield stability in the new environment. Therefore, stability analysis is mandatory. Using genotype and genotype into environment (GGE) biplot analysis found the GEI (genotype × environment interaction). Exotic hybrids G16, G4, and G1 performed superior and stable in test environments for studied traits, especially for average grain yield per plant and grain zinc content. These three hybrids gained strong\recommendations for introduction in Pakistan. [ABSTRACT FROM AUTHOR]
