In agricultural areas of the Cereal Program of the National Agrarian University La Molina, an experiment was carried out in the cultivation of wheat with the objective of evaluating its physiological response and production in the face of water deficit, for which, four genotypes were planted (the variety more planted on the coast, a mountain variety and two advanced lines of the program) in two environments (irrigation and water deficit), with a complete randomized block design in each environment, where each experimental unit consisted of five four-meter furrows. long, a distance of 0.35 between furrows and a density of 200 viable seeds per m2. Physiological, morphological and performance variables were evaluated. Background fertilization was carried out before sowing. A gravity irrigation system was used, where the water deficit environment received a last irrigation 20 days after sowing (DDS). The results showed an important effect in all genotypes in the drought environment, where the values of chlorophyll content and stomatal conductance were lower and canopy temperature were higher with respect to the irrigation environment. Likewise, it was observed that all genotypes in water deficit reached physiological maturity in fewer days, that is, they presented precocity. In water deficit, the genotypes reduced their yield by up to 50%; a reduction was also observed in plant height, spike length, number of grains and weight of 1000 grains. After the combined analysis, no interaction of the treatments with the environment was observed, only differences between the environments, where irrigation was superior to water deficit.
