Other Asian countries Induced mutations have also been widely used in many other Asian countries for breeding new varieties and in turn contributed to food security. Detailed information for Pakistan [19] and Vietnam [20] can be found elsewhere in this book. In the Republic of Korea, sesame ( Sesamum indicum ) yield has been increased more than twice (from 283 kg/ha to 720 kg/ha) due to development and release of 15 improved determinate type, high oil content mutant varieties having phytophthora blight resistance and good cooking quality. These mutants occupied 55% of the national acreage during the last two decades in Korea [21].
