CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Japanese Plant Breeders' Rights Application No. 31725, filed Jan. 4, 2017, which is incorporated by reference herein as if set forth in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid variety of northern highbush blueberry (Vaccinium corymbosum L.) named ‘RYOKU NH-13’. This novel variety was found by open pollination of ‘Chandler’, a seed parent variety, in the tests conducted for the period from 2003 to 2007 in Matsumoto-City, Nagano-prefecture, Japan. As stated below, ‘RYOKU NH-13’ has apparently different characteristics from those of the varieties ‘Chandler’ and ‘Blueray’, both being widely planted and being important varieties in the Chubu district of Japan.

SUMMARY OF THE INVENTION

Blueberry variety ‘RYOKU NH-13’ exhibits outstanding and distinguishing characteristics when grown under normal horticultural conditions in the area from Nagano-prefecture to the north of the Kanto in Japan, including:

• • (1) more upright plant growth habit and stronger plant vigor;
  • (2) comparatively early fruit ripening time (on average, around July 10 of each year in Matsumoto, Nagano, Japan);
  • (3) comparatively large fruit size;
  • (4) sweeter fruits;
  • (5) better taste balance of sweetness and acidity;
  • (6) smaller stem scar.

DETAILED BOTANICAL DESCRIPTION

A. Distinctive Characteristics of ‘RYOKU NY-11’

As described above, ‘RYOKU NH-13’ was obtained by the open pollination of ‘Chandler’, a seed parent (Note: the possible pollen parent might be ‘Blueray’). On Apr. 15, 2003, about 10,000 seeds of ‘Chandler’, which were cultivated in a field in Matsumoto-City, Nagano-prefecture, Japan, were seeded in plant seeding trays, and then transplanted to pots. The resulting seedlings (about 3,000) were planted in cultivation pots on May 1, 2004. Fructification of the planted seedlings were started from Jun. 20, 2007 (on Year 3), and about 200 plant individuals were selected based on the characteristics, including larger fruit size, better taste balance of sweetness and acidity, higher yield per plant, earlier ripening time, large and uniform fruits, etc.. For the about 200 selected plant individuals, test plots (each including about 20 cuttings per plant individual) were formed, where these plants were asexually propagated by cutting means. During the period from Jul. 20, 2009 to Dec. 25, 2016 and for 3 generations, the plants were propagated and examined for their characteristics based on the growth, yield and fruits quality in each test plot. For 10 test plots, the characteristics of the plants were observed for the period between the flowering time and the ripening time yearly for 5 years, and since neither variant nor off-type plant was observed for the period, the characterization of ‘RYOKU NH-13’ was finished on Dec. 25, 2016 and the breeding was completed.

‘RYOKU NH-13’ is a blueberry clone which can be distinguished from the important blueberry varieties ‘Chandler’ and ‘Blueray’, both of which are widely planted in the Chubu district of Japan, due to its characteristics including a more upright plant growth habit, stronger plant vigor, comparatively early fruit ripening time, comparatively large fruit size, sweeter fruits, better taste balance of sweetness and acidity, and smaller stem scar. From the above-described about 200 selected plant individuals, one plant individual, ‘RYOKU NH-13’, was selected out as described, and then 31 plants were propagated from ‘RYOKU NH-13’ by cutting means in Matsumoto, Nagano, Japan, and all the resulting plants were phenotypically indistinguishable from the original plant variety ‘RYOKU NH-13’. In addition, comparing to ‘Chandler’ and ‘Blueray’, the claimed plant ‘RYOKU NH-13’ has a more upright plant growth habit, about 1 week to 10 days earlier fruit ripening time (on average, around July 10 of each year in Matsumoto, Nagano, Japan), sweeter fruits, and smaller stem scar when compared to its related variety ‘Chandler’, and has stronger plant vigor, larger fruit size, better taste balance of sweetness and acidity, and smaller stem scar when compared to ‘Blueray’ (see Table 1 below). It should be noted that the plant age of all the plants of ‘RYOKU NH-13’, which were observed for botanical description, was 5 years.

The following data defining the characteristics of ‘RYOKU NH-13’ were collected from the asexual propagation by cutting means carried out in Matsumoto, Nagano, Japan. The plant history was taken on a plot of 10 five-year-old plants growing in Matsumoto, Nagano, Japan. ‘RYOKU NH-13’ has not been observed under all possible environmental conditions, and the measurements provide might therefore vary when grown in different environments. Where averages are given, the sample size was 10.

• 9. Resistance to disease, insects, and mites: ‘RYOKU NH-13’ grew vigorously and showed excellent bush survival in the field. It appears to be tolerant to stem blight (Botryosphaeria spp.) and root rot (Phytophthora cinnamoni), with very few young plants dying soon after planting. The response of ‘RYOKU NH-13’ to the various fungal species that cause summer leaf spots is typical of other northern highbush varieties, and fungicide applications may be needed after harvest in order to reduce foliar diseases and to retain leaves until autumn and make maximum flower bud set. Similarly, susceptibility to typical blueberry insect and mite pathogens, such as spotted wing drosophila (Drosophila suzukii), blueberry gall midge (Dasineura oxycoccana) and blueberry bud mite (Acalitus vaccini) is similar to other northern highbush cultivars.
