摘要：

Isolates of Drechslera teres that cause net or spot-type symptoms on barley (Hordeum vulgare) were collected in 1986 and 1987 from fields in different regions of France. Variations in pathogenicity were evaluated using 12 barley cultivars. The Middle-Eastern cultivars Arrivate and 79-S1O-10 were resistant to all isolates except R5 and S5. The Ethiopian cultivar Cl 5791, previously reported to be resistant, was susceptible to the R5 and S5 biotypes. There was a high correlation coefficient between the classification of cultivars for resistance to D. teres f. sp. teres and D. teres f. sp. maculata. A method for conserving the virulence of the isolates on straw is evaluated. The virulence level of the isolates was the same after 4 years of storage using this method.
