a Maturity group; b RB: reddish-brown colored lesion, TAN: tan-colored lesions, NIM: near immune reaction with no macroscopically visible lesions; c Disease severity was determined based on lesion density (percentage of infected area) on the first trifoliate leaves. A five-point scale was used as previously described [29,30] where 1 = no visible lesions, 2 = a few lesions with approximately 1–20% of the area infected, 3 = lesion density with approximately 21–50% of the area infected, 4 = substantial lesion density with approximately 51–80% of the area infected, and 5 = very heavy lesion density with approximately 81–100% of the area infected; d Sporulation was rated based on the relative percentage of lesions producing urediniospores on each plant tested using a 1-to-5 scale where 1 = no sporulation, 2 = less than 25% sporulation, 3 = 26 to 50% sporulation, 4 = 51–75% sporulation, and 5 = 76 to 100% of the lesions sporulating [30,31]; e Resistant check; f Means followed by the same letter within a column and maturity group are not significantly different by the least significant difference test at p ≤ 0.05 as determined by the SAS GLMMIX procedure; g Rpp2 and/or other gene(s); h Mapped to Rpp1 but is not the same allele as Rpp1b; i Susceptible check.
