Blažek J., Paprštein F., 2014. Development of fruit quality within top apple cultivars based on the consumer preference testing in last 34 years. Hort. Sci. (Prague), 41: 10-18.Results of all public consumer preference testing sessions included in this study were to be divided into 3 time periods. During the oldest period (1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990), with regard to overall qualities and appearance of fruits, the cv. Rubín was the most preferred. Next, it was followed by the cvs Fantazie, McIntosh, Gloster, and Melrose. In the subsequent period (1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001), the cv. Bohemia was in the first position in all respects including taste and fruit appearance. Following it in downward sequence were the cvs Rubín, King Jonagold, Jonagold, McIntosh and Melrose. In the latest period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013), again both in the total scoring and fruit appearance, Bohemia was the most preferred. It was followed in descending order by cvs Orion, Meteor, Jomured, HL 623 and Gold Bohemia. Considering fruit taste alone, however, the most preferred cultivar was Orion. According to the overall results of studies from thirty-three years, in which a total of 198 cultivars or genotypes were included, the most preferred was cv. Bohemia, followed by cvs Meteor, Rubín, HL 623, Andera, Gold Bohemia, King Jonagold and Jomured. Regarding fruit taste itself, the top cv. Bohemia was directly followed by cv. Gold Bohemia and by the selection HL 1834.Keywords: historic development; overall values; total scores; fruit appearance; cultivar assessing Since 1979, consumer preference testing of selected apple cultivars and advanced selections involving both specialists in the area and participants from the wide public are annually organized by the Research and Breeding Institute of Pomology Holovousy Ltd., Holovousy, Czech Republic. The main aims of the study were complex results of these testing and stating of long-time trends in development of fruit quality within new apple cultivars.

“…The larger trees of MM106 provide a larger distance of the target fruit from the reflective mulch. Therefore, the influence of reflective mulch on fruit colouration shows a more profound effect on small trees such as Braeburn and Elstar and Jonagold all on M9 rootstock Blanke 2005, 2011) [10,14] than on large trees (Table 5).…”

(1) Background: Climate change associated with a warm autumn often hampers the development of colouration of many fruits including late ripening apple varieties in New Zealand. (2) Objective: This study will provide detailed information on the possibility of enhancing colouration of apples under the diffuse light conditions in autumn in the southern hemisphere (SH). The aim is to obtain a larger proportion of fruit meeting the (red) colour market specifications, especially within the first picks, and to identify both the side of the fruit and its position within the tall trees canopy (3.5 m) as affected by reflective mulch on the ground spread at and over different times. (3) Material and methods: Reflective white textile mulch (Extenday®) was spread in the grassed alleyways 4 weeks or 2 weeks before the anticipated harvest in April on cv. Fuji and Pacific Rose apple trees without hail nets in the Northern Part of the South Island (41° S) of NZ. Fruit colour (blush) was determined by scoring and colourimeter during fruit maturation and at harvest, and fruit quality was determined at harvest by standard methods. (4) Results: (a) In cv. Pacific Rose apple, the reflective mulch increased the scored blush value from 1.5 (<50% blush) to 3.9 (ca. 75% blush) before the first pick, whereas the control fruit (without ExtendayR) reached a final score value of only 3.0. (b) Fruit colour improved after one week of exposure to reflective mulch in the SH. (c) The scored blush on fruit near the trunk with reflective mulch doubled (Pacific Rose) or tripled (Fuji) at harvest in comparison with trees with grass alleyways (control). (d) Two and four weeks of reflective mulch enhanced colouration of the down facing side for fruit of both cultivars, especially for fruit from the inside of the canopy near the tree trunk. However, reflective mulch significantly improved blush by 20% on fruit from the periphery of the canopies of the tall trees in both cultivars without significantly affecting fruit firmness, soluble solids, starch breakdown or ripeness. (5) Conclusions: The results from ca. 2000 colour measurements showed that the short exposure of at least two weeks of reflective mulch was sufficient for enhancing colouration for outside, inside and down facing sides of the fruit of both cultivars. As a result of this surprisingly short and efficient exposure time for these tall trees (3.5 m), the reflective mulch increased the portion of fruit harvested in the first pick by 8% (Fuji) and by 27% (Pacific Rose) with improved fruit storability or export quality and thereby increased financial returns to the grower in the SH.

Blažek J., Paprštein F., Zelený L., Křelinová J. (2015): Results of public tastings of apple novelties at the end of the storage seasons during the last 10 years. Hort. Sci. (Prague), 42: 53-60.From a total number of 62 apple samples included in this study, 42 cultivars or selections were evaluated after storing in standard conditions, and the remaining 20 in ultra low oxygen (ULO) storing conditions. The top leader regarding total taste quality was cv. Meteor, which obtained the highest total scoring value, and also in the mean sequence it was the number one cultivar. In the following position with regard to the total fruit quality was cv. King Jonagold. In a decreasing sequence of total fruit quality, the cultivars were classified in the following order: Rosabel, Andera, Angold, Berta and Meteor stored in ULO. In the case of fruit taste alone, Gold Bohemia was the total leader. Followed by cvs Rubinola and Andera. Regarding the character of the taste, cv. King Jonagold was relatively the sweetest, closely followed by cvs Pinova and Goldstar. On the opposite spectrum, with relatively the most acidic taste, were cvs Jonagold, Topaz and Rubin, all of which were stored in ULO conditions. Regarding fruit appearance cv. Melrose was evaluated as the most attractive looking apple. It was followed in this characteristic by the novelty cv. HL 212. Next in sequence were cvs Šampion (ULO), Benet, Gala Must (ULO), Angold and Andera.
