All beer barley cultivars tested were resistant or moderately resistant to the aphids, especially Asahi 5 and Haruna Nijo were similar to a wild line, H603 (W603), for checking resistant. However, these beer barleys contained much less gramine than the wild barley line, suggesting that another resistant factor(s) affects cereal aphid density. en-copyright= kn-copyright= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=1 ORCID= en-aut-name=KasaharaToshihiko en-aut-sei=Kasahara en-aut-mei=Toshihiko kn-aut-name=笠原敏彦 kn-aut-sei=笠原 kn-aut-mei=敏彦 aut-affil-num=2 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=3 ORCID= en-aut-name=SaeidMoharramipour en-aut-sei=Saeid en-aut-mei=Moharramipour kn-aut-name=SaeidMoharramipour kn-aut-sei=Saeid kn-aut-mei=Moharramipour aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Beer barley kn-keyword=Beer barley en-keyword=Cereal aphid kn-keyword=Cereal aphid en-keyword=Resistance kn-keyword=Resistance en-keyword=Gramine kn-keyword=Gramine END
