Other claims from this paper (7)
- Observation Pathotypes 63562, 63573 and 63762 had the highest frequency of occurrence of Puccinia triticina on wheat.
- Observation For the first time in this population, 25 entirely new pathotypes of Puccinia triticina were identified.
- Observation The genetic variability of the pathogen population was represented by 86 genetic formulae for virulence.
- Observation The most common virulence formula of Puccinia triticina was found in 37.9% of isolates.
- Observation Lr22a, Lr22b and Lr43 conferred immunity during the investigated period.
- Observation Lr1, Lr3ka, Lr9, Lr19, Lr25, Lr28, Lr40, Lr41, Lr42, Lr45, Lr47 and Lr50 showed very good to high efficiency.
- Observation Some Puccinia triticina pathotypes overcame the resistance conferred by the strong genes Lr9 and Lr19.
