Sporulation levels on Rpp-NILs, recurrent parent, and Rpp donor varieties inoculated with Phakopsora pachyrhizi. Average sporulation levels (SL) of P. pachyrhizi-inoculated leaflets. The average SL values were calculated from up to 30 lesions on leaflets. An average SL value of less than 1.5 was taken to be indicative of a resistant reaction (below the dotted line). Plots on the graph show the SL of assessed lesions. Red, BRP-2.5 (Brazil); orange, BRP-2.6 (Brazil); blue, E1-4-12 (Japan); green, MRP-13.18 (Mexico). Bars indicate the standard deviation (SD).
