Evaluation of Resistance to Fire Blight in Czech Pear Cultivar

Popis výsledku v původním jazyce

Newly bred Czech pear cultivars were tested for resistance to fire blight. Artificial inoculations were carried out in the period 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. The level of resistance was determined by percentage share of bacterial lesions to total length of shoots (in cm) after 40 days. 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´ showed strong symptoms ofinfection. Growth and yield characteristics of three cultivars on rootstocks resistant to fire blight were evaluated. Based on the present results, OHxF 87 rootstock appears to be the best for all three cultivars concerning growth and yie
