Abstract

FLORES CARRERA, Laura Stephanie et al. Yield stability of 36 cultivars had collected in the Estado de Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.8, pp.1905-1917. ISSN 2007-0934.

This work was done in the spring-summer 2013 in five locations in the Estado de Mexico to assess the stability of the performance of 36 bean cultivars. A series of experiments was chosen in a randomized complete block design with three replications per location. The highly significant differences were observed among cultivars, between localities and their interaction (IGA) suggest that there is enough genetic variability to start a new program of plant breeding, the center environments of the Estado de Mexico are heterogeneous and significant IGA difficult to identify outstanding cultivars. These results were confirmed by applying the AMMI model and Eberhart and Russell changing the classification of stability with the proposal Carballo and Márquez. The best environments were San Nicolás Guadalupe and Barrio de Guadalupe, located in the State of Mexico municipalities of San Felipe del Progreso and San Mateo Atenco. The grain yield in five locations ranged from 0.24 to 6 t ha-1. Although there was no stable cultivars, the most outstanding were identified as T2, T4, T5, T6, T7, T26 and T30 (2.05 to 2.61 t ha-1), collected in the municipalities of Acambay, Jocotitlán, Zinacantepec and Metepec; except T4, which showed better response in good environments and was consistent, T12, T23, T28 and T36 responded better in good environments but were inconsistent.
