The old walnut (Juglans regia L.) genotype called “Esterhazy II” was well-known in the Austro-Hungarian Monarchy before World War II, and it can still be found in the Austrian, German and Swiss backyard gardens today. Unfortunately, nowadays, vegetatively propagated progenies of the original “Esterhazy II” are not available anymore around the world because walnut grafting started later than this genotype had become well-known. Although various accessions with “Esterhazy II”-“blood“ are available, it is difficult to determine which one can be considered true or the most similar to the original one. In this paper, phenological and nut morphological characteristics of an “Esterhazy II” specimen planted in a Hungarian gene bank were compared to the varieties “Milotai 10” and “Chandler”. Examined characteristics were: budbreak, blossom time, type of dichogamy, ripening time, nut and kernel features. An additional SSR fingerprinting was used to identify identical genotypes and to demonstrate the relatedness of the analyzed “Esterhazy II” genotype to the other Hungarian walnut cultivars. It can be concluded that under the name “Esterhazy II”, several different genotypes can be observed. All the checked characteristics except budbreak fitted well with the previous descriptions. Our results confirmed that the examined “Esterhazy II” genotype shows high similarity to the “original“ “Esterhazy II” described in the literature.

“…• Verder wordt er sinds ongeveer 10 jaar op grotere schaal geëxperimenteerd met heggenteelt. Hierbij worden snoeiregime en snoeiwijze gevarieerd (Aletà et al, 2005;Ramos et al, 1992;Olson et al, 2005).…”

“…Ook wordt geëxperimenteerd met de frequentie van de snoei van de hagen, waarbij in Spanje 2-3 jarige interval geschikt lijkt voor een aantal hoofdrassen. Een interval langer dan 3 jaar leidde tot te veel "zelf-overschaduwing" en productieremming (Ramos et al, 1992;Aletà et al, 2005;Ninot et al, 2000). Bij een haagplantsysteem speelt de keuze van het ras een grote rol bij de productie.…”
