摘　　要：本研究以引自瑞典的大麦核质互作型雄性不育系和恢复系为材料，用我国不同品种（系）与其测交，回文转育，结果筛选出９３２５７３、９３２５７４二个具开颖、抗大麦黄花叶病的保持系。育成了９３０７５３、９３０７５４二个自交不育率分别为９８．１７％和９７．８３％的不育系及９４８７３９、９４８７１８、９４８６７９、９４８７２０等４个恢复系。恢复结实率均在９７％以上。Three lines of karyocytoplasmic interaction type MS from Sweden were testcrossed and backcrossed with various barley varieties. From the offsprings the followinglines were screened:two MS lines'930753 and 930754'with self-sterility rates at 98.17%and 97.83 % respectively 1 two MS maintainer lines'932573 and 932574'with open glumesand resistance to BYMV;and four MS restorer lines'948739,948718,948720,948679',therestoration rates of the four restorer are over 97.0%.
