DURABIL TY OF RESISTANCE TO LEAF RUST DISEASE ( Puccinia recondite F, Sp. tritici) IN A NUMBER OF WHEAT MONOGENIC LINES
Thilly one le.?1 rust monogenic lines ot wheal (Lr's) were evaluated lor ine« rp.Slstance under B rtir:cial field condilion I r 4 years ( 2000 - 2003 ) at GemmaizJ Rc 'ie;!(C!) S~rHlon. The tested L r genes w ere varied greatly in disease s everity but remained constant over the four years. They divided inlO lour groups based on tnelr raactlons . Genes Lr 9, Lr18, Lr19, Lr 21, Lr 38, Lr 42 and Lr 43 were highly resistant. l.r za. Lr 2ll, Lr 20, Lr 25. LJ 28, Lr 3.().
