ADAPTABILITY AND STABILITY FOR IRON AND ZINC IN COWPEA BY AMMI ANALYSIS

ABSTRACT Iron and zinc deficiency is one of the main problems affecting vulnerable populations in Colombian Caribbean, thereby generating malnutrition from consumption foods with low content essential minerals. The objective this study was to evaluate genotype-environment interaction for iron accumulation grains 10 cowpea bean genotypes by additive effects multiplicative (AMMI) model select most stable ones stimulate their planting or as parents genetic improvement program. Nine promising lines a commercial control were evaluated using randomized complete block design treatments four replications environments northern Colombia second semester 2017 first 2018. adaptability stability analysis done AMMI model. results showed highly significant differences at level environments, genotypes, zinc, demostrating differential test environments. Genotypes 2 3 expressed greater contents seed; while genotype 1, recorded it contents. These three outperformed and, therefore, can be recommended used
