%X The frequencies of virulence genes for 61 isolates of Erysiphe graminis f.sp.tritici from different ecological areas of Shanxi Province were monitored.The results show that Pm2,Pm4a,Pm4b,Pm13,Pm20,PmXBD,Pm2 6,Pm4 8,Pm2 Mli,Pm4b Mli and Pm5 6 are effective resistant genes to Erysiphe graminis f.sp.tritici and may be applicated as resistant parents;Pm6,Pm21,Pm2 Ta and Pm1 2 9 have applicable values in some extent;Pm1,Pm3a,Pm3d,Pm3f,Pm17 and Pm19 are little applicable value in breeding;Pm3b,Pm3c,Pm3e,Pm5,Pm7 and Pm8 have no applicable values in breeding if they are utilized as the only resistant sources.Finally,the virulence frequencies are arranged in order and the common prevailing virulent genes in different ecological areas are selected.
