Abstract

In 1997-1998 virulence of the wheat leaf rust population was studied on Thatcher near isogenic lines with Lr1, Lr2a, Lr2b, Lr2c, Lr3. Lr9, Lrll, Lrl5, Lrl7, Lrl9, Lr21, Lr23, Lr24, Lr26 and Lr28. On these NILs 11 pathotypes were determined in 1997, and 8 inl998. All rust samples were avirulent onLr9, Lr19, Lr24 and Lr28.There was a relatively low frequency of virulence on Lrl, Lr2a and Lr2b. Most rust samples were virulent on Lr2c, Lr11, Lr15, Lr17, Lr23 and Lr26. All samples were virulent on Lr3 and Lr21. The identified pathotypes conformed with races 61SaBa*, 77SaBa, 2SaBa, 12SaBa, 57SaBa, 6SaBa, 61*, 77 and 6. Races 61SaBa*, 77SaBa and 2SaBa prevailed in 1997, races 61 SaBa*, 77SaBa and 12SaBa were prevalent in 1998. Races 6 and 6SaBa were found for the first time. Data on Lr genes in recently registered winter wheat cultivars are presented.
