    The lack of micronutrients in most foods has caused people to present hidden hunger, therefore, scientific and political entities are looking for alternatives to reduce the number affected. The International Center for Tropical Agriculture together with Haverts Plus have obtained rice cultivars with high zinc content to contribute to the increase of minerals through the biofortification of crops; within the framework of this project, it was proposed to evaluate the agronomic and nutritional behavior of five rice cultivars under irrigation conditions, a transplant method in order to measure the behavior of advanced cultivars, the experiment was established in November 2018 to April 2019 in the experimental area of the Faculty of Agricultural Sciences of the University of Córdoba, Colombia located at coordinates 8°47′16″ north latitude and 75°5′28″ west longitude. A randomized complete block design was made with five treatments which corresponded to three cultivars biofortified with zinc (BF14AR021, BF14AR032, BF14AR035) and two controls, one local (CICA4) and one commercial (IR64) for which agronomic characteristics were assessed. , of milling and nutritional quality; Highly significant and significant differences were detected for all variables except in the number of clusters and white center, in terms of zinc content, the biofortified cultivar BF14AR021 obtained the highest value with 23.50 ppm. In addition, phenotypic correlations were made between performance and other response variables; which reflected that 23.07% were revealing at 5 and 1%, these values oscillating between 0.48 and 0.92.
