Proceedings of the International TRIGO Wheat Yield Potential p. 10-12Summary: Wheat is grown in Mexico mainly under irrigation in the northwestern and central regions of the country. Mexico bridges a range of latitudes, providing an array of topography, environments, soil types and epidemiological zones susceptible to different diseases. These characteristics offer important information about the performance and adaptability of outstanding wheat lines that eventually may be the basis for the development and international release of high-yielding varieties through the Wheat Yield Consortium (WYC). The evaluated material is listed in Table 1, and the location of the nurseries (environments, E) is shown in Figure 1. Data were recorded for: 1) Plant height (PH); 2) days to heading (DH); 3) days to maturity (DM); 4) harvest index (HI); 5) grain yield (GY); 6) biomass (BIO); 7) spikes per square meter (SSM); 8), thousand kernel weight (TKW); and 9) grains per square meter (GSM). HI, BIO and SSM were not considered for Obregon. Data obtained for all recorded variables were subjected to an analysis of variance within each site. Additionally, combined analyses of variance were performed over various locations and regions (northwestern and central) to estimate the statistical significance of effects due to genotypes (G), E and the genotype by environment (GxE) interaction. The AMMI1 programming routine described by Vargas and Crossa (2000) was employed to explain the GxE interaction estimated by the combined analysis of variance.
