  1. The Pst isolates were from single aecial cups produced on barberry (Berberis shensiana) after inoculation with basidiospores derived from germinated teliospores. The teliospores were collected from infected grass leaves in middle March, 2014
  2. aThe Chinese differential host set genotypes: 1 = Trigo Eureka (Yr6), 2 = Fulhard (Unknown), 3 = Lutescenes 128 (Unknown), 4 = Mentana (YrMen1, YrMen2, YrMen3), 5 = Virgilio (YrVir1, YrVir2), 6 = Abbondanza (YrAbb1, YrAbb2), 7 = Early Piemium (Unknown), 8 = Funo (YrA, +), 9 = Danish 1 (Yr3), 10 = Jubilejina 2 (YrJu1, YrJu2, YrJu3, YrJu4), 11 = Fengchan 3 (Yr1,, YrFc1, YrFc2), 12 = Lovrin 13 (Yr9, +), 13 = Kangyin 655 (Yr1, YrKy1, YrKy2), 14 = Suwon 11 (YrSu), 15 = Zhong 4 (Unknown), 16 = Lovrin 10 (Yr9), 17 = Hybrid 46 (Yr3b, Yr4b, YrH46), 18 = Triticum spelta var. album (Yr5), 19 = Guinong 22 (Yr24, = Yr26), 20 = Mingxian 169, used as a susceptible check. A = Avirulence (infection types 0 to 2), V = Virulence (infection types 3 to 4), and AV/VA = Mixed infection types
  3. b,c,dG22, HyG and SuG indicate three different races virulent to wheat genotypes Guinong 22, Hybrid 46 and Suwon 11, respectively. “/” indicates that isolates are not virulent to any of major genotypes (Guinong 22, Hybrid 46 and Suwon 11)
