Orchard performance of new plum cultivars on two rootstocks in a trial at Holovousy in 1998-2003

Abstract

Thirteen plum cultivars on two rootstocks (Myrobalan and Wangenheim Prune seedlings) were studied in a trial established in the spring of 1998 at spacings 5 × 1.5 m. Trees were trained as spindles. Čačanska najbolja was the most vigorous in this trial, followed by Čačanska rana, Herman and Domestic Prune. The weakest tree vigour was observed on Wegierka Dabrowicka, followed by Čačanska rodna and Empress. Čačanska najbolja, Wegierka Dabrowicka and Valor had the highest yield per tree, whereas Čačanska rana had the lowest yields. Bluefre was the most precocious cultivar. Wegierka Dabrowicka had the highest yield efficiency followed by Empress and Valor. On the contrary, Čačanska rana, Early Blue and Domestic Prune belonged to the least productive cultivars. Trees on Wangenheim Prune seedlings grew about one third weaker than those on Myrobalan seedlings but their yield efficiency was about 31% higher although their yields per tree were about 12% lower. The largest fruits were recorded with Bluefre. Čačanska rana, Empress, Valor and Oneida were also ranked among large fruit varieties with minimum differences between them. The mean harvest season of evaluated cultivars started by Herman on the 12 th July and ended by Oneida on the 9 th September. Valor and Empress had the best performance of tree growth, bearing habit and fruit size, which indicates their good suitability for the modern types of plum orchard. Bluefre may also be of some interest for growers because of the best precocity and large fruit size, and Oneida for prolonging the whole harvest season.

Growth, fruit size, yield performance and micronutrient status of plum trees (Prunus domestica L.)

“…Meland (2005) found that OPA was the most vigorous. Similarly, BLU grew vigorously in our trial, but was reported as slow growing in the Czech Republic (Blažek et al 2004). Generally, our data were in a good agreement with results of above authors, although ČLE in our study had low tree growth.…”

“…All reminding cultivars could be classified like plums with medium fruit size (Blažek and Pištěková 2009), except ČRA and ČNA. These cultivars could be classified as large fruits cultivars on the basis of summarized results (Blažek et al 2004). Mean FW and its variation recorded in this trial corresponded quite well to data observed in literature (Halapija-Kazija et al 2009).…”

Final evaluation of nine plum cultivars grafted onto two rootstocks in a trial established in 1998 at Holovousy

“…In comparison to the results recorded during the first period of testing (Blažek et al 2004), Sanctus Hubertus grafted onto Myrobalan showed the most vigorous behaviour. Similarly, Bluefree was the medium vigorous at the initial period while it was clearly classified as the least vigorous at the end.…”

“…Some preliminary results from this trial that were mainly focused on different aspect of the rootstocks effects, were published (Blažek et al 2004.…”

Selection of Prune (<i>Prunus domestica</i> L.) Cultivars Suitable for the East Asian Temperate Monsoon Climate: Ripening Characteristics and Fruit Qualities of Certain Prunes in a Warm Southwest Region of Japan

“…In fresh prune production regions, including some European countries and parts of North America, the 'Stanley', 'President', and 'Bluefre' are often cultivated (Ramming and Cociu, 1991). In Europe, where breeding of prune cultivars has been actively conducted, various cultivars are grown including domestic breed, imported, and traditionally raised cultivars (Blažek et al, 2004;Bozhkova, 2014;Okie and Ramming, 1999;Rakićević et al, 2008;Šebek, 2013). In Japan, growing areas for 26 prune cultivars have been recorded, most of which are imported (MAFF, 2013).…”
