The aim of the work was to study an occurrence and intensity of septoria tritici blotch on wheat in different regions of Poland as well as reaction of winter wheat cultivars and breeding lines to infection by <em>Mycosphaerella graminicola</em> (Fuckel) Schroeter (an. <em>Septoria tritici</em> ( Rob. ex Desm .) under field conditions. Observation conducted during 1994-1996 indicated on occurrence of septoria tritici blotch each year and on important infection degree of winter wheat by <em>Mycosphaerella gruminicola</em> in some regions of the country. The highest infection was noted in 1995 and the lowest in 1994. Infection degree for majority of cultivars was quite high. Some cultivars and lines were characterized by very high infection. Among them were the old (Kujawianka Więcławska and Wysokolitewka Sztywnosłoma) and the newest (Tercja) cultivars. On some old cultivars (Leszczyńska Wczesna and Żelazna) even no traces of infection were observed although favourable weather condition existance and the presence of neighbourhood diseased plants. Field observation of cultivars and breeding lines showed different reaction of tested wheat genotypes to <em>Mycosphaerella graminicola</em> infection.

The response of Polish winter wheat genotypes to <i>M.graminicola</i> (preliminary experiments and cultivar collections) was observed in different regions of Poland. Observations were carried out in 1995-1999. The winter wheat genotypes showed a broad spectrum of reaction to this pathogen. Between 1997 and 1999 the highest degree of infection on winter wheat breeding lines was noted in Kończewice. During this time no genotypes free from infection were observed (preliminary breeding experiments). Cultivars with no symptoms of <i>Septoria tritici</i> blotch (Leszczyńska Wczesna and Żelazna) were found among old genotypes in Słupia Wielka only in earlier experiments (1995-1996). In the years 1997-1999 the winter wheat cultivars were classified into groups on the basis of their response to the pathogen. The degree of infection for the majority cultivars was quite high.

Two experimental sets of selected winter wheat cultivars, breeding lines, old Czech and Slovak landraces and wheat wild relatives were infected with three isolates (R-116, UH-105, BR-331) of Mycosphaerella graminicola (anamorph Septoria tritici) isolated in the Czech Republic. Groups of cultivars with different disease severity to all three isolates of the pathogen were found. Differences between old Czech and Slovak landraces and wild wheat relatives were larger than between modern wheat cultivars and breeding materials. In experiment one the isolate BR-331 differed significantly from the other two isolates in virulence to the tested modern wheat cultivars and breeding lines. The method is considered as suitable for preliminary screening in wheat resistance breeding or phytopathological testing and as a complement to field tests. &nbsp; &nbsp;

Developmental patterns of growth have been studied in nine spring and 10 winter wheat cultivars and in a number of crosses involving both groups. Among the spring cultivars five responded to vernalization while four did not. There was a very wide range in responsiveness to vernalization among the winter cultivars, ranging from the responsive Winter Minflor to Jones Fife which appeared not to respond at all to the '30-day vernalization test'. The spring habit of growth was governed by three dominant genes, any one of which was able to inhibit the expression of the winter habit. Progress has been made in establishing relationships among several spring cultivars. Those carrying the gene Sk, either alone or in combination with others, appeared to be non-responsive to vernalization. In the absence of Sk all spring cultivars so far tested exhibited a positive response. Winter selections made from spring-winter crosses always resembled the winter parent with respect to the intensity of the winter characteristic. While all winter wheats carry recessive alleles at all three loci, the differences in expression which exist between them appear to have been due to the presence of multiple recessive alleles at these loci. Further evidence of the association of leaf and spikelet numbers with days to ear emergence is presented.

Reaction of six winter wheat cultivars and lines (Vlasta, Šárka, Charger, 00ST022, SG-U8044C a SG-U2113B) to <i>Mycosphaerella graminicola</i> isolate BR-331 and UH-05 on leaf segments of the detached second seedling leaf of cultivars placed on water agar with bezimidazole in clear plastic box were tested. The isolate BR-331 produced high occurrence of the disease in the cultivar Šárka, middle occurrence (the percentage covered by lesions bearing pycnidia) in the cultivar Vlasta and SG-U8044C and low occurrence in the line 00ST0022. The isolate UH-105 produced high occurrence in the cultivar 00ST022 and middle occurrence in the cultivar Vlasta. The cultivar Charger was resistant. The cultivar Šárka was attacked at least. Results show on different virulence of <i>M. graminicola</i> isolates to wheat cultivars.
