Description
| - ln an experimental orchard, J 4 apple cultivars bred in Holovousy and registered in the Czech Republic during 1994-2011 have been evaluated for 12 years in comparison with four standard ones most comrnonly grown bere. Trees were planted on M9 rootstock in the spacing of 4 x 1 m and trained like spindles. Zuzana ev had the most vigorous trees. whicb was followed by Primadela and Resista. On tbe contrary, Selena had the smallest canopy, followcd by Rubinstep, Vysočina and Julia. Regarding disease performance Primadela, Resista, Seleoa, Starkresa and Vysočina were entirely resistant to apple scab (Venturia inaequa/is). Another three, Julia, Angold and Produkta were rated as highly tolerant to the disease. The higbest levels of tolerance to powdery mildew were recorded on Meteor, Nabella and on thc standard cul ti var Rubín. Occurrence of fruit rot was very negligible on Starkresa, Benet, Vysočina and Meteor. The most productive was Rucla with a mean year harvest equal to 34.4 tons per hectare. In decreasing order, it was followed by Nabella, Resista, Produkta, Primadcla, Angold and Vysocina, all of which were better than tbc standard ones. Regarding fruit size the largest one was Meteor followed by Jonagold, Angold, Benet and Nabella. The cultivar that was first in taste was Rucla, followed by Benet, Rubín, Rubinstep, Starkresa and Meteor.
