International testing of incomplete resistance against brown rust (Puccinia recondita) in IPHR wheat lines.
Promising wheat lines from FAO's International Program for Horizontal Resistance (IPHR) in Brazil and Zambia were tested in the Netherlands against brown rust (Puccinia recondita. f.sp.tritici). Race nursery tests were performed on isolated field plots using five monopustular isolates from the Netherlands representing at least four races. Mature plants of several lines showed high incomplete resistance. For most lines, the reactions to the different races showed a high uniformity. Apparently, lines selected according to the IPHR principles can perform well when exposed to brown rust isolates to which they have not been exposed during selection.
