英语. Seedling reactions of 25 advanced barley lines and 5 barley cultivars to one virulent isolate of Rhychosporium commune were determined under greenhouse conditions. Cultivar Avcý 2002 was found highly resistant and cvs Kalaycý 97 and Bülbül 89 were found susceptible. Barley cultivars Karatay 94 and Efes 3 exhibited a highly susceptible reaction to R. commune. Among the advanced lines, 9 was the most resistant genotype. Barley lines 3, 7, and 11 showed a moderately resistant reaction to the isolate. Genotypes 1, 2, 4, 6, 10, 13, 16, 18, 19, 20, 24, and 25 were susceptible and genotypes 5, 8, 12, 14, 15, 17, 21, 22, and 23 were highly susceptible to the R. commune isolate. Cultivar Avcý 2002 and advanced barley lines 3, 7, 9, and 11 could be used as resistance sources.

土耳其. Yirmibeþ ileri kademe arpa ýslah hattý ve 5 arpa çeþidinin Rhychosporium commune'nin virülent bir izolatýna karþý fide dönemi tepkileri sera þartlarýnda tespit edilmiþtir. Avcý 2002 çeþidi yüksek derecede dayanýklý bulunurken Kalaycý 97 ve Bülbül 89 çeþitleri hassas olarak bulunmuþtur. Karatay 94 ve Efes 3 çeþitleri ise yüksek derecede hassas olarak bulunmuþlardýr. Ýleri kademe arpa hatlarý içerisinde 9 numaralý hat en dayanýklý hat olarak görülmüþ olup, 3, 7 ve 11 numaralý genotipler orta derecede dayanýklý reaksiyon sergilemiþlerdir. Ýleri kademe arpa hatlarýndan 1, 2, 4, 6, 10, 13, 16, 18, 19, 20, 24 ve 25 numaralý genotipler hassas olarak bulunurken, 5, 8, 12, 14, 15, 17, 21, 22 ve 23 numaralý genotipler R. commune izolatýna yüksek derecede hassas olarak bulunmuþlardýr. Avcý 2002 arpa çeþidi ve 3, 7, 9 ve 11 numaralý ileri kademe arpa hatlarý dayanýklýlýk kaynaðý olarak kullanýlabilir.
