Evaluation of Resistance to Fire Blight in Czech Pear Cultivar

Popis výsledku v původním jazyce

Newly bred Czech pear cultivars (14 cultivars) were tested for resistance to fire blight. Tests were carried out in the research station of RICP in Slany. Tested cultivars were grown in technical isolation. Artificial inoculations were carried out in theperiod of strong extending growth. Inoculations were done by decapitation of shoot tips by scissors dipped in the bacterial suspension (concentration 106 cfu). The bacterial suspension was composed of 5 virulent strains of Erwinia amylovora. Virulence of pathogen was verified by testing on forced shoots of Pyrus ussuriensis. The level of resistance was determined by percentage share of bacterial lesions to total length of shoots (in cm) after 40 days. We used adjusted USDA scale for evaluation. Tests proved high resistance to fire blight in cultivar ´Bohemica´ (higher than in ´Lucasova´) and ´Jana´. This resistance was comparable to newly bred US-625-63-4. On the other hand, cultivars ´Isolda´, ´Vonka´, ´Beta´, ´Decora´ and ´Petra´ sho
