“…The radiosensitivity of plants also played a huge role in determining the effects of gamma irradiation. The sensitivity of plants to mutagens differs depending on their species and genotypes (Quintana et al, 2019). Based on the radiosensitivity test in this study, the LD 50 was determined at 752.50 Gy, in the sensitivity effect can be seen at 800 Gy with a significant reduction of survival percentage, plant height, and root length, and increment in chromosomal abnormalities and clastogenic percentages.…”

Gamma irradiation is an effective and widely used method in the agricultural sector to alter the traits of plants especially for commercialization purposes and as a mitigation measure to ensure food security in the future. Vigna radiata (mung bean) is one of the most important legume crops in Asian countries that is not fully exploited. Therefore, this research aimed to determine the effects of gamma irradiation on the cytology and growth of mung beans. The mung bean seeds were exposed to different doses of gamma radiation; 0, 200, 400, 600, 800, and 1000 Gy. The increasing dose of gamma irradiation caused an insignificant decrease (p>0.05) in the mitotic index of V. radiata meristematic cells. However, a significant increase at p<0.05 in the percentage of clastogenic chromosomal aberration was observed in the meristematic cells of plants irradiated at 800 and 1000 Gy. The survival percentage, plant height, and root length were inversely proportional to the percentage of chromosomal aberration and clastogenic abnormalities when the irradiation dose exceeded the LD50 (752.50 Gy). In conclusion, gamma rays greatly induced clastogenic abnormalities which have varying impacts on the cytology and growth of V. radiata plants.

El Perú, cuenta con más de 425 000 ha cultivadas de café, distribuidas entre más de 25 variedades comerciales. Lamentablemente, estas fueron introducidas casi siempre de manera informal; pero en los últimos años, esta situación parece cambiar. Nuestro país, no cuenta con una entidad dedicada a desarrollar variedades mejoradas de café. Por eso, la importancia de introducir variedades mejoradas a nuestro país; pero de manera ordenada y siguiendo los protocolos establecidos por las entidades oficiales. Este documento tiene como objetivo presentar una revisión sobre las características de estas variedades y algunas experiencias de su comportamiento en nuestro país, información importante para una especie introducida que se cultiva hace más de 100 años en la selva peruana. En el germoplasma colectado en nuestro país (“germoplasma peruano”), se encontraron variedades con rendimiento mayores al promedio nacional, con incidencia baja de roya y con puntajes en taza iguales o mayores a los 80 puntos. Destacan los genotipos pertenecientes al grupo de los Catimores, como la UNACAF-90, UNACAF-135. En los próximos años, se espera tener información disponible en nuestro país, del comportamiento de las 35 variedades como Ruiru, Paraíso, Kartila 1, Batian, Andungsari, Catiga MG2, USDA 762, que vienen siendo evaluadas en el marco del ensayo mundial de variedades, ejecutada por WCR y que en nuestro país coordina la JNC. De igual manera de las 46 variedades introducidas en el 2021 por el INIA desde el CATIE de Costa Rica y que se encuentran bajo cuarentena en la EE Pichanaki en la selva central, para su posterior evaluación en el campo.

The Arabica coffee is predominantly self-pollinated plants thereby contributing to low genetic diversity. The effort to increase the genetic diversity of Arabica coffee through crossing strategy is time-consuming, and induce mutation is necessary to enhance the rate of genetic variation. The aims of this study were to observe the effect of gamma-ray irradiation on the growth of apical and axillary bud cuttings and to determine the value of LD50 on apical cuttings and Arabica coffee axillaries. The study was conducted at the Tissue Culture Laboratory, Industrial and Beverage Crops Research Institute, from January to December in 2018.. The planting material that was irradiated was Arabica coffee plantlets resulting from somatic embryogenesis propagation. Irradiation is carried out at the National Nuclear Energy Agency. The irradiated plantlets were cut and subcultured onto MS medium without growth regulators, 30 g L-1 sucrose, and 2.5 g L-1 phytagel were added. The design used a completely randomized design with 10 replications. The treatments tested were the dose of gamma-ray irradiation (0, 10, 20, 30, 40, and 50 Gy). The results showed that gamma-ray irradiation had an effect on all observed parameters. The mortality percentage of apical shoot cuttings began to be found at 30 Gy, while axillary cuttings at 20 Gy increased with an increasing dose of gamma-ray irradiation. The number of shoots and leaves varied between irradiation doses on both apical and axillary cuttings. The LD50 value of apical shoot cuttings was 36.80 Gy, while axillary cuttings were 22.24 Gy
