Application of physical modification techniques such as the radiation of gamma rays could induce rust resistance and improve the performance of wheat plants through the development of new products. During the growing seasons of 2020-2021 and 2021-2022, two field experiments were done to see how well five types of bread wheat (NING MAI 50-0CHN, SAKHA 93, GIZA 168, SIDS 12, and SKAUZ) did when they were exposed to 5, 10, 15, 20, and 25 Kr of gamma rays. The experiments looked at how well the rust was controlled, how much yield was produced, and how the seedlings grew. Results showed that wheat genotypes significantly differed in rust infection and other parameters in both seasons at different gamma-ray ratios. Sakha 93 gave high resistance to yellow rust with high seedling dry weight and seedling vigor index 2, but Giza 168 gave the highest leaf rust resistance with increased doses of gamma rays. On the other hand, the SKAUZ genotype surpassed other genotypes in germination percentage and grain yield in both seasons. A dose of 25 kr was the most beneficial for rust resistance and yield attributes in comparison to the control, while a dose of 5 kr caused improvement in seedling parameters. Results exhibited that the interaction effect between wheat genotypes and gamma rays was significant on all studied traits in both seasons. Finally, it is concluded that gamma rays play an important role in inducing rust resistance and improving grain yield.

Climate change is one of the biggest threats to plant species around the world. As one of the most important crops worldwide, rice is an awfully climate-sensitive agro-ecosystem. Therefore, Giza 183 will be released in 2023 as a high-yielding variety that has been adapted to mitigate climate change. This new variety is the product of cross-breeding between Giza 178 and SKC 23893 in 2010. The first generation, "F1,” of this cross was evaluated in 2011 and planted as the F2 generation in 2012. Sequentially, the next generations from F3 to F6 were evaluated in the pedigree trails from 2013 to 2016, under cross number “GZ 10848." Five promising sister lines of GZ 10848 were selected and evaluated in the preliminary yield trail (GZ 10848-1-2-2-1, GZ 10848-1-2-2-2, GZ 10848-1-2-4-5, GZ 10848-1-2-5-3, and GZ 10848-1-2-5-6). The results revealed that the promising line GZ 10848-1-2-2-1 “Giza 183” surpassed all selected lines. Accordingly, Giza 183 was evaluated from 2017 to 2022 in multi -location yield trails at Sakha, Gemmiza, and Zarzoura as normal conditions and El-Sirw as saline conditions, as well as in regional, final, and verification yield trails. The evaluation resulted in a significant superiority of the yield of Giza 183 over Giza 178, with shorter growth duration and blast resistance. The new variety grain yield recorded 10.88, 10.47, 11.30, 10.60, and 10.70 t/ha during the 2017 to 2022 seasons under normal conditions, respectively, with a total duration of 122 days. while the grain yield for Giza 178 was recoded at 10.50, 10.54, 9.90, 10.00, 9.80, and 10.30 t/ha during the same seasons and conditions, with a total duration of 135 days. Furthermore, Giza 183 exhibited a higher yield than Giza 178 as a salt tolerance check variety at a rate of 0.800 – 0.160 t/ha under saline conditions at El-Sirw Agricultural Research Station in different years of evaluation. Giza 183 showed a high level of blast resistance in blast nursery and trap varieties in the field and artificial inoculation under greenhouse conditions. Finally, the new rice variety Giza 183 is resistant to stem borer and has high grain quality traits

Jerusalem artichoke is grown in different regions and is widely consumed as food. It has a distinct flavor, and, it is an excellent source of inulin, plant, phytochemicals, and some functional nutritional ingredients including dietary fiber and minerals. This study was conducted to assess the effect of varieties and harvest time at 240 and 270 days after planting (December 15 and January 15) respectively, on the total yield of tubers ton /fed as well as kg/plant, average tubers weight, and chemical composition. Also, to test the possibility of producing chips from two varieties of Jerusalem artichoke at two harvest times, frying at different temperatures degrees (170°C, 180°C) and using some technological treatments. The chemical composition of raw materials, processed chips, organoleptic changes, color parameters, and hardness values of the final product were studied. The obtained results showed that the Fuseau variety and the second harvest time were better in terms of the total yield of tubers, the average tuber weight, chemical components, and the production of chips than the Balady variety. It can also be concluded that treatment No. 4 (in which the slices were soaked in a solution containing 2% acetic acid and 1% citric acid), especially, at a temperature of 180 °C, was the best in preserving many important components, as well as imparting distinctive color properties. In addition, this treatment led to improve sensory quality characteristics based on the sensory evaluation of the majority of panelists. Hence, Jerusalem artichoke chips are recommended as snack foods.
