On Friday July 27, our colleagues at Agua FrĂa were visited by two students from Instituto TecnolĂłgico de Huejutla, Hidalgo, and two farmers from the same location. The visitors were given an introduction to CIMMYT, and gained a greater understanding of the center’s work in the areas of physiology, entomology, genetic resources, and tropical maize research. They learned how and when the agronomic data from trials—for example on flowering, plant height, ear size, lodging, etc—are collected during the breeding cycle. They toured the work areas, and at the end of the tour their hosts presented them with free training material on the collection of data in the field, and field identification of maize plagues, diseases and other problems.
