| Abstract: |
| Based on the idea and experience of previous authors, as well as the concept of quantitative resistance, 170 candidate entries of wheat that might possess horizontal resistance against stripe rust (Puccinia striiformis) were collected and tested with different races of the pathogen. Results of seedling and adult plant (some entries) tests for resistance indicated that 59 entries were highly resistant, with no or little race specificity, 33entries gave p,s/O type reaction, showing horizontal tendency. 17 entries showed vertical resistance., and 9 entries were highly susceptible during the seedling stage. The prospect of the utilization of different types of candidate horizontally resistant materlals was also discussed. |
