The main purpose for inducing mutation into rice crops is to increase the mutation rate in a short ‎period of time and to develop new plant varieties with useful agronomical traits in order for ‎sustainable food production to become a possibility. The occurrence of a spontaneous mutation ‎frequency rate is very rare and exceptional, making it difficult for plant breeders to exploit. ‎Commonly, mMutations are commonly induced by chemical (e.g., ethyl methane sulfonate) and physical (e.g., ‎gamma radiation) mutagen treatment of both seed and vegetatively propagated crops. Here, movrer than ‎‎10,000 seeds of the rice variety Gohar were initially subjected to mutagenesis using ethyl methane ‎sulfonate (EMS). The EMS-treated seeds were rinsed with deionized water, and then sown in the ‎seedbed. A population of about 5,250 M1 plants was developed. At maturity, a single panicle was ‎picked from each plant. The following year, to achieve 3,510 M2 plants, the seedlings selected ‎from the nursery -grown panicles were grown in the field. Then, one panicle was chosen from ‎each mature plant in M2 to get the M3 population. In the M4 population, the selection criteria ‎were early maturity, high- fertility rate, dwarf growth habit, and plant type. Eventually, six plants ‎possessing early maturing traits were selected for commercial release.‎
