Checks CLN2037B (Ph-3), WV700 (Ph-2), and susceptible parents G2-6-20-15B and CLN2777G showed expected reactions to isolates Pi-237 and Pi39A after seedling inoculation. The five CLN3241prefixed lines and LBR-11 were resistant (scores =2.0) to both isolates (Table 4) and subsequent marker analysis confirmed that these entries were homozygous for Ph-2 and Ph-3.
