Evolution of distinct populations of Puccinia recondita f. sp. tritici in Canada

1991-03-01

Abstract excerpt

The eastern and prairie populations of Puccinia recondita f. sp. tritici in Canada had similar identities and frequencies of Unified Numeration (UN) races during the initial years of the annual wheat leaf rust survey (1931-1937) when susceptible cultivars were grown in both regions. Pathogenicity associations within each population also were very similar during this period. Differences between the eastern and prai...
