Rice cultivation system in Iran is completely irrigated and, production level in 2015 was impressive with 3.5 million tons from approximately 0.550 million hectares (Karbalaei Aghamolki et al., 2015). Further iIncrease in theg Iranian rice production within limitations, in available land and, water resources and challenges of climate change is a difficult task (Dorosti et al., 2016). Hence, it is important to maintain rice diversity in the production areas for improved varieties as well as traditional landraces in equitable proportions. Induced genetic variation is thea basic requirement for crop improvement ftor gain a long term sustainable food production (Jain, 2010). Plant breeders have successfully recombined the desired genes from the existeding available gene pool andwith the related plant species. by crossing hHybridization and successfully obtained new cultivars with desirable characteristics, such as high yield, biotic and abiotic stress tolerant. The goal of induced mutations is to enhance the mutation frequency rate in order to select appropriate variants for the purpose of breeding crops efficiently (Jain, 2010; El-Degwy, 2013). Induced mutation has over the past 50 years played a major role in the development of superior crop varieties (Jain, 2005).
