This means that the synthetic varieties had different responses to environmental changes (Reyes 1990). Regarding stability parameters, the synthetic varieties SINT 3 SEQ SINT 9 SEQ SINT 12, SEQ and the commercial check VS-536 were characterized as “stable†and displayed good grain yield and agronomic characteristics. Because of this, they are defined as “desirablesâ€. Synthetic varieties SINT 9 SEQ SINT 3 SEQ and SINT 12 SEQ showed yield gains of 18%,25% and 9% respectively over the commercial check VS-536 under severe stress water restrictions. In regard to environment indices, Cotaxtla under WW registered the best yield with an environment index of 2.07, while Isla and San Andres Tuxtla in: the rainy season registered negative environment indexes of -2.27 and -2:13 for each location respectively. Regarding agronomic characteristics, the experimental synthetics SYNT 9 SEQ, SYNT 3 SEQ and SYNT 12 SEQ achieved a high score for plant and ear aspect. There was no lodging or important damage by ear rot. SYNT 9 SEQ and SYNT 12 SEQ were 25 cm. and 27 cm shorter than the commercial check VS-536. | ||
