摘要： There are about 20,000 sesame germplasm accessions in the world. South Korea, India, China, and some African countries are the main countries reserving sesame germplasm. However, sesame is the sole cultivated Sesamum species for seed production. The relatively narrow genetic base limits the progress of the world's sesame breeding. Deficiency of the elite accessions also hinders the variety improvement. In the past decades, mutagenesis techniques have been applied for creation of new sesame germplasm and for breeding varieties. In this section, we summarize the main progress in mutation induction methods and mutant creation in sesame. Some key mutants with determinacy, dwarf, and other elite traits are enumerated in detail. The importance of mutagenesis approach in sesame is also discussed.
