However, the environmental challenges that reduce the productivity and spread of rice cultivation are many, especially water stress due to the lack of water needed for its cultivation. Accordingly, this investigation set out with great efficiency in order to infer new rice mutants<br>characterized by their high water deficit tolerance as well, its high yielding across using several safe doses of gamma rays. Further, the present study succeeded in genetic improvement for rice variety Sakha 101 after exposure it to several doses of gamma rays, through the events of large physiologically, genetically and biochemical changes that had the greatest impact on raising its drought tolerance degree besides, eliciting five improved novel rice mutants from it. Also, the six rice accessions were evaluated under normal and drought through estimating some yield, physiological and biochemical attributes for screening the most mutants tolerated for water stress in 2022 and 2023 seasons. The final results confirmed that the rice mutants number (3, 4 &amp; 5) were recorded the biggest trend of drought tolerance then followed by the mutants number (1 &amp; 2) compared to the local cultivar under water stress treatment&nbsp;<br>compared to the standard experiment. Therefore, these novel rice mutants will be future high-yielding and drought-tolerant rice varieties and this is the biggest goal in this work.&nbsp;</p> . .
