| Abstract/Contents: | Isolates from 2 field samples of Puccinia coronata were selected for increased aggressiveness on 4 of 10 resistant Lolium perenne clonal lines. Two lines which were formerly highly resistant became highly susceptible to the selected isolates but 2 which were formerly moderately resistant became only moderately susceptible. Thus, moderate resistance, although no less likely to be race-specific, was more stable than a high level of resistance. Cultures from highly resistant lines did not show increased aggressiveness on the cvs. from which the resistant lines had been selected; hence individual genes of major effect were unimportant in determining varietal resistance. In contrast, cultures from moderately resistant lines were substantially more aggressive on their corresponding varieties. Three varieties contained many genes which tended to buffer changes in virulence of the rust. |
