运用电离辐射或化学诱变剂改良芝麻栽培种的研究已在很多国家进行,且成效显著。至今,已发现了有限花序的突变体,以及培育出矮秆、节短、早熟、宜于密植和机械收割的品系;获得了抗病性和抗逆性强的突变体,并育成高产品系或品种;通过诱变还能出现高油分、高亚油酸的突变体;利用γ射线和EMS可以诱发雄性不育。 Research on the use of ionizing radiation or chemical mutagens to improve sesame cultivars has been conducted in many countries and has achieved remarkable results. To date, mutants with limited inflorescences have been found, as well as breeds that are dwarfed, short, precocious, suitable for close planting and mechanical harvesting; mutants with high disease resistance and resistance have been obtained and bred to high-yielding lines Or varieties; high oil, high linoleic acid mutants can also occur through mutagenesis; use of gamma rays and EMS can induce male sterility.
