TOSQUY-VALLE, Oscar Hugo et al. Rincón Grande: a variety of black beans for Veracruz and Chiapas. Rev. Mex. Cienc. Agríc [online]. 2025, vol.16, n.3, e3646.  Epub 12-Ago-2025. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v16i3.3646.

Diseases, drought, and soil acidity are the main factors reducing bean yields in Chiapas and Veracruz, Mexico. To help solve this problem, the National Institute of Forestry, Agriculture, and Livestock Research developed the new variety of small-grained opaque black beans called Rincón Grande. This was obtained from selections of the Jamapa Plus and XRAV-187-3 cross. Rincón Grande has a cycle of between 85 and 90 days from sowing to harvest and stands out for its high yield (>2.2 t ha-1), resistance to rust, anthracnose and common mosaic, as well as tolerance to golden yellow mosaic. It is a variety with wide adaptation and yield stability in the tropical and subtropical areas of Veracruz and Chiapas. In 2020-2021, it was validated in producers fields in Veracruz, confirming its high productive potential. Rincón Grande has the characteristics of the type of beans demanded by consumers in southeastern Mexico.
