27 isogenic lines with the genetic background from Avocet, 131 germplasms of relatively clear resistance genotype, 59 registered commercial varieties, multi-location test materials for registration and broadly used resistance donors, as well as the susceptible control, Mingxian 169, were sown in lines without replication in the disease nursery located at Ya'an City (N:29°57′09.6″, E:103°07′11.9″, 525.1m), Zitong (N:31°44′07.0″, E:105°10′48.5″, 484.1m) and Jiange (N:31°52′21.5″, E:105°16′23.5″, 481m). The isogenic lines containing Yr5、Yr10,Yr15 and Yr26, registered commercial varieties Chuanmai 43, 46, 47, Chuannong18, 23, Mianmai 39, 41, 42, Neimai 8 and Xingmai 2, multi-location test accesses C1, C5, 30375, and SW18155,resistance donors Mega (Yr3,4), Hybrid 46 (Yr3b,4b,H46), 93-1-22v-2, CP93-10-1-1-1, SMT-35, SMT-47, Guinong 22, Guinong 22-1 as well as 'Guizhou Laimai +MO' were consistently detected in disease nurseries both in 2008 and 2009. 27 accessions of the 216 accessions had resistance in Ya'an , but susceptible characteristics in Zitong and Jiange, only 5 accessions had resistance in Zitong or Jiange but susceptible characteristics in Ya'an, which indicated a weaker virulence of the pathogen in Ya'an than that in Zitong and neighboring Jiange.
