영문 초록

To utilize wild alien gene sources for multi-resistance to several major diseases of sesame, two wild species, Sesamum alatum (2n=26) and S. radiatum (2n=64) were examined on the agronomical characters and cross affinities with cultivated species. S. radiatum showed perennial habit while S. alatum appeared on annual plant habitate like cultivated species. Both species are branched and late maturing with light grain weight. They were highly resistance to seedling blight, phytophthora blight, fusarium wilt and leaf blight. Their cross affinities with cultivated species were very high with bearing capsules from 8 to 70% in the almost all the crosses. However, those seeds were not germinated mainly due to immaturity. Therefore it may be necessary to rescue fertilized-embryos by in vitro technique.
