| dc.description | The cultivation of rice (Oryza sativa L.) is one of the fundamental pillars of global food security, being a primary source of calories for a large part of the population, as the global demand for food continues to increase, the on farmers and agricultural scientists to develop rice varieties more resistant to pressure. He set himself as a goal; determine the genetic improvement of rice cultivars (Oryza sativa L.) using native or wild species. Regarding the methodology, a basic research was initiated with a descriptive-bibliographic approach, where a methodology focused on the exhaustive literature review was used, adapted to the qualitative nature of the study. In reference to the results, the analysis of the relevance of native or wild species in the genetic improvement of rice cultivars reveals the critical importance of these varieties in the diversification and strengthening of genetic improvement programs. In conclusion, the importance of genetic improvement of rice crops is determined based on integral processes in wild species, as well as in situations adaptable to environmental conditions. In recommendation, strengthen the research and application of genetic improvement techniques that involve the integration of genes from native or wild species in rice cultivars, this strategy can contribute significantly to obtaining more resistant and adaptable varieties, thus improving the sustainability of rice production | es_ES |

| dc.description.abstract | El cultivo de arroz (Oryza sativa L.) es uno de los pilares fundamentales de la seguridad alimentaria mundial, siendo una fuente primaria de calorías para una gran parte de la población, a medida que la demanda global de alimentos sigue aumentando, se intensifica la presión sobre los agricultores y científicos agrícolas para desarrollar variedades de arroz más resistentes. Se planteó como objetivo; determinar el mejoramiento genético de cultivares de arroz (Oryza sativa L.) utilizando especies nativas o silvestres. Por su parte en la metodología, se estableció una investigación básica con un enfoque descriptivo-bibliográfico, donde se empleó una metodología centrada en la revisión exhaustiva de literatura, adaptada a la naturaleza cualitativa del estudio. En referencia a los resultados, el análisis de la relevancia de las especies nativas o silvestres en el mejoramiento genético de cultivares de arroz revela la importancia crítica de estas variedades en la diversificación y fortalecimiento de los programas de mejoramiento genético. En conclusión, se determina la importancia de la mejora genética de los sembríos de arroz basados en los procesos integrales en especies silvestres, así como en situaciones adaptables a condiciones ambientales. En recomendación, fortalecer la investigación y aplicación de técnicas de mejoramiento genético que involucren la integración de genes provenientes de especies nativas o silvestres en cultivares de arroz, esta estrategia puede contribuir significativamente a la obtención de variedades más resistentes y adaptables, mejorando así la sostenibilidad de la producción de arroz. | es_ES |
