Other claims from this paper (11)
- Observation The tested wheat cultivars differed significantly in disease parameters and yield components.
- Observation Sids-12 had fast stripe rust development.
- Observation Gemmeiza-11 had fast stripe rust development.
- Observation Gemmeiza-7 had fast stripe rust development.
- Observation Sids-12, Gemmeiza-11 and Gemmeiza-7 had the highest estimated and actual losses in thousand-kernel weight and grain yield.
- Observation Gemmeiza-10 had slow stripe rust development.
- Observation Gemmeiza-9 had slow stripe rust development.
- Observation Gemmeiza-10 and Gemmeiza-9 had the lowest estimated and actual losses in thousand-kernel weight and grain yield.
- Association The relation between final rust severity and estimated losses in kernel weight and grain yield was more stable than relations using AUDPC, rAUDPC or r-value.
- Method / resource The authors conclude that yield loss per feddan can be predicted from final rust severity.
- Recommendation The authors recommend chemical control of stripe rust in all tested cultivars, especially Sids-12, Gemmeiza-11 and Gemmeiza-7.
