TOSQUY-VALLE, Oscar Hugo et al. Adaptation of black bean genotypes to different environments of Veracruz and Chiapas. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.6, pp.1301-1312.  Epub Oct 02, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i6.1658.

In the present investigation, the main additive effects and multiplicative interaction (AMMI) model was used to determine the yield and stability of 12 lines and two varieties of opaque black beans, evaluated during 2016 and 2017, in 10 environments of Veracruz and Chiapas, Mexico. The trial was established in experimental design random blocks with three repetitions and plots of three rows of 5 m in length. The grain yield was quantified, which was analyzed individually by environment and combined (environments-genotypes) of the 10 test environments, stability parameters were also estimated with the AMMI model. The Experimental Field Ixtacuaco and Rincon Grande, Veracruz, in autumn-winter 2016-2017 under residual humidity, were the environments that combined low interaction and high productivity, making them ideal for identifying genotypes with high and stable performance. Venustiano Carranza, Chiapas, in autumn-winter of 2016-2017, El Rubi, Veracrus, in winter-spring of 2017 with irrigation and New Mexico, Chiapas, in summer of 2016, in whitewashed acid soil, were the environments that more interacted with genotypes. The Jamapa Plus/XRAV-187-3-1-8 line showed the least interaction with the environment (much higher than that shown by the Negro Comapa and Negro Grijalva varieties), as well as high average yield (1 437.3 kg ha-1), while Jamapa Plus/XRAV-187-3-1-2, was the most profitable line (1 504.3 kg ha-1), but its adaptation was specific, mainly in environments with edaphic acid stress in the center from Chiapas and by terminal drought in the center of Veracruz.
