Radiación gamma para inducción de mutagénesis en pasto rosado [Melinis repens (Willd.) Zizka]

Abstract: La radiación gamma puede ser utilizada para conocer el rango de radiosensibilidad (RRS) en pastos con fines de mejoramiento genético por mutagénesis. El pasto rosado es una especie invasora que puede ser mejorada en valor nutricional u otras características. El objetivo de este estudio fue determinar la dosis óptima de radiación gamma para inducir mutaciones efectivas en pasto rosado mediante dosis letal media (DL50) y reducción media de crecimiento (GR50). El estudio fue realizado en campo, laboratorio e inve… Show more

“…The seed was mixed all together and then stored during six months. Prior to the irradiation process, a quality analysis was carried out on the seed, which contained 4% of humidity and 35% of the seed germinated [21]. In March 2015, the irradiation process was carried out at the Moscamed Complex of the National Service of Health, Safety and Food Quality (SENASICA) of the Ministry of Agriculture and Rural Development (SADER), located in Metapa de Domı ´nguez, Chiapas, Mexico.…”

“…Other biotechnological techniques, such as mutagenic physical and chemical agents to help genetic variant production with improved characteristics, have been implemented (Ángeles-Espino et al, 2013). Among the physical mutagenic agents, the most used is gamma radiation, generally coming from Co60, a radioactive isotope with high ionizing capacity used in vegetable cells research and food technology to obtain resistant specimens to different types of biotic and abiotic stress, improve yield and response to disease or chemical agents and even enhance ornamental characteristics (Corrales-Lerma et al, 2019;Balvoa-Caguana et al, 2021).…”

“…Por ejemplo, el 70% del trigo (Triticum aestivum L.) sembrado en Italia provino de cultivos mutados (González, 2014). Corrales et al (2019) sugirieron que la inducción de mutaciones podría ser una opción viable para establecer mejora genética. Esto se debe a que la práctica es capaz de inducir mutabilidad con agentes mutagénicos.…”
