Yield, Phenotypical Stability and Micronutrients Contents in the Biofortified Bean in the Colombian Sub-humid Caribbean
The intake of protein and micronutrients in the Colombian sub-humid Caribbean has been a concern in recent years. About 57 % of the population in the sub-humid Caribbean region, has a deficit of amino acids —iron (Fe) and zinc (Zn)— in their diet. This study shows the results of the agronomic evaluation of the performance and quality of nine genotypes of biofortified bean and one local control in four environments of Cesar. The methodology included chemical and microbiological soil characterization, reaction evaluation to pests and diseases, multi-sited valuation by AMMI and selection of two varieties with better yield and nutritional content by ACP. In addition to these two prioritized genotypes, the Pearson correlation coefficient between seed micronutrient content for locations and years was determined. The biofortified genotypes surpassed the control group significantly in both yield and precocity. According to the ACP, the biofortified group differed from the control group in iron and zinc content in the seed, confirming its superior characteristics in nutritional quality, and resistance to pests and diseases. The AMMI showed that the genotype SMR43 reflected stability and predictability between environments and SMR39 had specific adaptation in the best location for grain production. Both genotypes retained high levels of micronutrients between locations and years as according to the Pearson correlation.
