An agreement has been established institutional work for the evaluation of 9 varieties of maize generated by the Maize Program Phylogenetic Pairumani Center (PFIC-Cochabamba). The varieties of maize have been established test plots in 2 locations of the protected area Iñao, and the Experimental Centre Bañado, inattentiveness of the cooperators, plots of communities were invaded by animals, but was evaluated the experimental plot of the experimental Centre Bathed of the Academic Unit of Monteagudo, part of the University San Francisco Xavier de Chuquisaca, in the experimental plot were arranged 9 varieties of corn and a local witness, the plot was established on an area of 705 m2, each variety corresponded four furrows spaced between grooves 0.75 m, in which 3 seeds were deposited at a distance of 0,50 m. The following agronomic traits were recorded: Days male and female flowering, plant height and ear, appearance of plant cover cob, cob appearance, grain type and yield in tons / ha. Realized assessments and data analysis found that study varieties in susceptibility to water stress and not very favorable reaction to high temperatures, causing a floral desynchronization, all varieties showed susceptibility to foliar and ear rot diseases. Analyzed the performance was determined that the local variety Canario outyielded all varieties under study (1.76 tons / ha), followed by the variety Aychasara-102 (1.12 tons / ha), one of the best of among the varieties studied.
