CAGAŠ B., MARKOVÁ J. (1985): Spezializierung des Rostes Puccinia poae-nemoralis Otth auf Poa pratensis L. und Poa palustris L. Česká Mykologie 39(1): 39-43 (published: 1985)
abstract
Populations of the rust fungus Puccinia poae-nemoralis isolated from Poa pratensis and Poa palustris represent special forms highly specialized to their host species. Resistant cultivars and ecotypes may be used in breeding programs. Morphological differences between the two forms are minimal, but paraphyses wall thickness varies.
CAGAŠ B. (1984): Unterschiedliche Virulenz der Kronenrostpopulationen (Puccinia coronata Corda var. coronata f. sp. festucae) in der ČSSR. Česká Mykologie 38(1): 31-38 (published: 1984)
abstract
The differences in the virulence of the crown rust populations of Puccinia coronata Corda var. coronata f. sp. festucae in Czechoslovakia were studied by field infestation of selected clones of Festuca pratensis Huds. at 8 sites under various environmental conditions in 1978–1979. The results, complemented by greenhouse tests on the offspring of the clones, confirmed the existence of at least two rust populations with different virulence levels. This underlines the necessity of testing resistant plant varieties at different localities or using mixed populations of the rust in breeding for resistance.

abstract
Analysis of the host plant range of the important parasite of Festuca pratensis Huds. — the crown rust Puccinia coronata Corda var. coronata — showed that this is indeed the graminicolous form of this rust species. Positive infection was observed in 24 grass species out of 174 tested from the Poaceae family. The most significant hosts with practical importance in the spread of this rust include Festuca pratensis Huds., Festuca gigantea (L.) Will., Cynosurus cristatus L., Lolium remotum Schrank, Lolium rigidum Gand., and Lolium temulentum L. The highest number of host plants was found among the tribes Festuceae and Phalarideae.
