| Abstract | ||||
| 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 change sensitive agro-ecosystem. Wherefore, Giza 183 is 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 F2 generation in 2012. Sequentially, next generations from F3 to F6 were evaluated in the pedigree trails during 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-locations yield trails at Sakha, Gemmiza and Zarzoura as normal condition and El-Sirw as saline condition, and 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 2017 to 2022 seasons under normal condition respectively, with total duration 122 days. | ||||
