VEGA ALVAREZ, Isrrael et al. Tlaxcala, research on native and improved corn: problems, fields of knowledge and new challenges. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.3, pp.539-551.  Epub 08-Ago-2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i3.2888.

Corn is the crop of greatest economic, social, cultural and political importance in Tlaxcala, in 2019 47.6% of the state agricultural area was sown. However, the problems related to its production, improvement and conservation are diverse, complex and progressive. Currently, the well-being of society is associated with the value that scientific knowledge adds to products and services, so the objective of the essay was to quantify and contrast some components of the published studies regarding corn in the state, to recognize their main trends. The documentary research was carried out through metasearch engines, bibliographic databases, library web portals, as well as specialized book and journal search engines. Two hundred forty-two documents published from 1951 to 2020 with a trend of progressive increase over time were recorded, of which 78.5% refer to native corn and 21.5% to improved materials. The fields of study with the highest frequency were technology, genetic improvement, social anthropology and productivity, which represent 51.2% of the total. Research has been conducted in the 60 municipalities of the state, most of it in Huamantla, Españita, Ixtacuixtla and Ixtenco. The institutions that have participated are 42, most of the documents were generated by COLPOS, INIFAP and BUAP. It seems that the published studies are not enough to explain all the factors and solve the problem. That is why it is imperative that researchers formulate a plan aimed at concrete results, which trigger changes in favor of farmers, population and environment.
