摘要：

The lentil accession ILL7537 was resistant in glasshouse bioassays to isolates of Ascochyta lentis Vassilievsky from a range of Australian pathotype groups, confirming its status as a highly resistant cultivated accession. Two dominant complementary genes were determined to condition the genetic mechanism and mode of inheritance of resistance in ILL7537. Accession ILL7537 was screened with molecular markers that were linked to, and flanking, the major resistance gene AbR(1) from the accession ILL5588. The absence of all of the markers from the AbR(1) linkage group indicated that the resistance mechanism in ILL7537 was potentially novel.
