Abstract
Young plants of wheat varieties bred in Martonvasar and others with known genetic backgrounds were inoculated under greenhouse conditions with two isolates of Drechslera tritici-repentis (Pyrenophora tritici-repentis) (Pti2 right arrow race 1, DW5 right arrow race 5). The area under the disease progress curve (AUDPC) was calculated from the values of lesion types at various dates. Statistically significant differences in susceptibility were revealed by analysis of variance on the varieties studied. On the basis of two years of data, a degree of infection similar to that observed for susceptible 'Glenlea' was recorded for the durum wheat varieties 'Martondur 3', 'Mv Makaroni' and 'Mv Maxi', and for the bread wheat varieties 'Bezostaya 1', 'TAM 107' and 'Martonvasari 4'. For 'Atlas 66' and 'Disponent', which are regarded as resistance sources, the degree of infection was negligible. Several varieties bred in Martonvasar, 'Mv Mezofold', 'Mv Magvas', 'Mv Emma' and 'Mv Magdalena', exhibited resistance similar to that of the resistance sources. The resistant control genotype 'M-3' exhibited the lowest AUDPC value. All the other varieties tested had a significantly higher degree of infection
