- Abstract
Wheat production in Mexico depends on more than 90% of the irrigated areas, which are classified as having a high water shortage, so varieties that are efficient in the use of water must be planted. In such a way that the objective of the investigation was to evaluate the behavior of the yield and its components of genotypes in function of the decrease of irrigation sheets (LR). Eight varieties of bread wheat and four LR were used. Genotypes were established in a split-plot design with large plots arranged as a randomized full-block design, with two replications. LR reductions of 1 to 0.8, 0.6, and 0.4 m decreased grain yield by 14.4, 37.6, and 76.8%, respectively. In limiting humidity (0.4 m) the number of spikes and biological yield decreased 63.7 and 73.3%. Grain yield was correlated with the number of grains and spikes per square meter. When the LR decreased from 1 to 0.8 m, Rebeca F2000 and Temporalera M87 presented grain yields greater than 6.5 t ha-1 associated with high biological yields. While Temporalera M87, in the 0.4 m sheet, was the one with the highest biological yield, number of grains and grain yield with 2.4 t ha-1. Therefore, genotypes and yield components were identified to help in the selection process with higher yield potential in limiting humidity conditions.
