“…This variant again stays outside the forecast (Ergün et al, 2023a), despite a fairly large sample size. To increase the reliability of the forecast, as previously pointed out by M. Hassine et al (2023), it is necessary to expand the set of genotypes used in the study substantially. First of all, SA and DMS (additionally) as mutagenic factors show a more significant dependence on the specific features of genotype-mutagenic interaction, i.e., they depend on the DNA structure of the source material of the site variety, as was mentioned earlier by H. Shimelis et al (2019), with a clear differentiation from genetically determined responsiveness to mutagenic effects.…”

Identification of new opportunities in the use of certain ecogenetic factors for the genetic improvement of winter wheat is a vital component of improving existing cereal agrocenoses within the framework of the food security strategy. The purpose of this study was to demonstrate the potential of substances with prominent genetic activity in inducing potentially beneficial changes and to establish the possibility of obtaining optimised schemes for obtaining new forms and more controlled trait variability. Mutations were detected by visual observation and biometric and biochemical analysis from the second generation to the sixth, with the inheritance of the detected traits in subsequent generations being checked. The study presented the possibilities of the mutation process for certain genetic and breeding-value forms, the specific features of induction of such traits, which makes it possible to increase the predictability of obtaining the necessary mutant lines and partially controlled high variability in certain traits. It was found that the most promising for use is the complex application of moderate doses of sodium azide and dimethyl sulphate as ecogenetic factors. It was shown that in combination with three varieties among the ones under study (Kalancha, Polyanka, Pochayna), it is possible to create highly efficient genotype-mutagenic systems with increased yield of valuable forms. The increase in mutagenic depression using more harmful substances can be substantially offset by an increase in the proportion of beneficial changes. The negative side is their complex nature. The nature of the ecogenetic factor is no less significant than the concentration of the mutagen or the genotype of the original form, which is sometimes overlooked. It was confirmed that the use of these factors is quite promising in terms of obtaining small biochemical changes (micromutations). Several promising mutant lines were identified that have a comprehensive improvement in grain yield and quality without additional negative changes. The findings of this study can be used in breeding programmes to create new varieties of winter wheat

“…G amma radiation, a form of radiation, has been extensively employed in diverse domains such as agriculture and food preservation (Venugopalan and Suprasanna, 2022). It has been utilized to improve the quality and safety of agricultural goods and to investigate its impact on plant biology (Aly et al, 2021), such as plant breeding (Kiani et al, 2022;Hassine et al, 2023), pest control (Soufbaf and Abedi, 2023), and food preservation (Mshelia et al, 2023). The impact of gamma radiation on living species, including plants, has been extensively studied and documented, revealing its ability to cause biological, chemical, and physical alterations (Sawarkar and Mansoori, 2023).…”

This study investigated the potential of gamma radiation to enhance the quality of dwarf napier grass (Pennisetum purpureum cv. Mot) cultivated in acidic soil, with a focus on its macro-mineral content and rumen fluid characteristics. The research findings focus on the impact of gamma radiation solely on macro minerals and rumen fluids, enhancing our insights into innovative approaches for improving livestock nutrition in regions with prevalent acidic soils. The experiment involved the application of various gamma radiation doses (0, 5, 10, 15, 20, 25, and 30 Gy). Four replications were done using a randomized block design, with 25 Pennisetum purpureum cv. Mot seeds in each repetition, totalling 700 seeds. The plants were grown in acidic soil with a pH of approximately 4.5-5. After two months of growth, the plants were harvested, and various parameters were analyzed. The results of the research indicated that the application of a 15 Gy dosage significantly enhanced the absorption of P (p<0.01), N (p<0.01), and Ca (p<0.01) in the plant. Additionally, gamma irradiation at a 25 Gy dosage demonstrated a notable effect, resulting in the highest calcium (Ca) content (p<0.01). However, the treatment did not exhibit a significant impact on pH (p > 0.05) in the rumen fluid, while NH3 (p<0.01) and VFA (p<0.01) parameters in the rumen fluid were significantly affected. The optimal dosage for the rumen fluid parameters NH3 and VFA was found to be 15 Gy. Overall, it can be concluded from this study that gamma irradiation doses of 15 Gy can enhance the nutritional content of Pennisetum purpureum cv. Mot cultivated on acidic soil, particularly when evaluated based on mineral content and rumen fluid parameters.
