영문 초록

This study was conducted to select breeding lines resistant to Phytophthora blight by using five varietal diallel crosses. B-67 and IS 103 lines proved as moderate resistant to sesame blight showed relatively lower percentage of diseased plants than susceptible varieties in seedling test. Significant general combining ability for reducing disease development was observed in B-67 and IS 103 and its degree was gerater in B-67 than in IS 103 line. Magnitude of dominant gene effect was greater than additive gene effect and many dominant genes were involved for resistance. More than 800 plants wer selected as resistant in the F₂ generation derived from Ansan/B-67, B-67/Danbaek, B-67/IS 103 and B-67/Yusung crosses.
