The ‘Zodiac’ fruit are smaller and glossier than ‘Columbia Star’ with a flavor that is slightly less aromatic and characterized more by its sweetness with good sugar/acid balance and an excellent texture that combines firm but not overly tough skin and smooth internal quality with very small seeds. The fruit quality and flavor are better than ‘Black Diamond’. ‘Zodiac’ yields were typically similar to or slightly higher than ‘Columbia’ in trials held in Aurora, Oreg.

Abstract

A new and distinct blackberry cultivar that originated from seed produced from a cross between the thornless maternal blackberry plant ‘ORDS 2707-1’ (unpatented) and the thornless paternal blackberry plant ‘ORDS 2785-2’ (unpatented)). This new blackberry cultivar can be distinguished by its high yields of small-to-medium sized, uniformly shaped, glossy, and distinctly conical berries that can be machine harvested with good firmness and quality for a trailing type of blackberry. The berries are well suited for processing, with an excellent flavor characterized by mild sweetness, and a good sugar/acid balance. The new and distinct blackberry variety has fruit that are borne on vigorous canes which combine two distinct sources of genetic thornlessness (‘Austin Thornless’, ‘Lincoln Logan’) from the respective female and male parent.

Description

Latin name of the genus and species of the plant claimed: ‘ZODIAC’ is a blackberry plant that is Rubus subg. Rubus Watson.
Variety denomination: The new blackberry plant claimed is of the variety denominated ‘Zodiac’ Rubus subg. Rubus Watson.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct blackberry cultivar designated ‘Zodiac’ and botanically known as Rubus subg. Rubus Watson. This new thornless blackberry cultivar was discovered in Corvallis, Oreg. in July 2011, and is the result of a 2008 cross between the maternal blackberry plant ‘ORUS 2707-1’ (unpatented) and the paternal blackberry plant ‘ORUS 2785-2’ (unpatented). ‘ORUS 2707-1’ was a selection from a cross of the thorny trailing blackberry ‘ORUS 1368-1’ (unpatented) and thornless trailing blackberry ‘NZ 9351-4’ (unpatented). ‘ORUS 2785-2’ was a selection from a cross of the wild Rubus ursinus blackberry accession ‘GP 4-21’ (unpatented) and the thornless trailing blackberry ‘Waldo’ (unpatented). ‘Zodiac’ thornlessness is derived from a combination of the ‘Lincoln Logan’ (unpatented) source on its maternal side, and the ‘Austin Thornless’ (unpatented) source on its paternal side. The original seedling of the new cultivar was asexually propagated in Benton County, Oreg. The new cultivar was established in vitro from a cane cutting and microcuttings have been taken and rooted from this sort of culture. The cultivar was referred to as ‘ORUS 4222-1’ internally as an experimental designation prior to release. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.
SUMMARY OF THE NEW PLANT
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Oregon. The new cultivar is thornless and possesses a trailing growth habit. The new cultivar ripens in the mid-season for a trailing type, one week later than ‘Columbia Star’ (U.S. Plant Pat. No. 25,532). The new cultivar has high plant vigor and favorable lateral fruiting architecture compared to current cultivar standards, with a plant vigor rating similar to ‘Columbia Star’ and higher than ‘Black Diamond’ (unpatented), and a higher fruit per-lateral count than ‘Columbia Star’ and on par with ‘Black Diamond’. Thus, the new cultivar appears to favorably combine the greater vegetative vigor and lateral lengths of ‘Columbia Star’ with the higher number of fruits per-lateral of ‘Black Diamond’ in a single variety. The cultivar demonstrated higher average yields than ‘Black Diamond’ and ‘Columbia Star’ in a 2017-planted trial in Aurora, Oreg. from 2019-2020, and higher yields in a 2019-planted trial in 2021 at the same location. The new cultivar has medium-size berries which release easily and possess sufficient firmness, skin toughness, and abrasion resistance to be machine harvestable. The fruit possess a high gloss and uniformly conical shape that narrows toward the tip of the berry, lending a distinct appearance. The new cultivar's fruit possessed higher soluble solids and acidity than ‘Black Diamond’ and ‘Columbia Star’ based on samples measured in 2016 and have excellent flavor and texture when eaten fresh.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES
‘Zodiac’ differs from the female parent blackberry plant ORUS 2707-1 in that it has darker fruit color with fewer purple drupelets, well-suited firmness for machine harvest, smaller fruit size (4.7-5.3 g), similar sweetness (12.4-13.7% Brix), and similar productivity (6.3-7.6 tons/acre). By comparison, ORUS 2707-1 (unpatented) has larger fruit (7.9 g), similar sweetness (13.2% Brix), and similar productivity (7.8 tons/acre), but is softer and tends to purple, making it less well suited for machine harvest.
‘Zodiac’ differs from the male parent blackberry plant ‘ORUS 2785-2’ in that it has fruit well-suited for machine harvest, larger fruit size (4.7-5.3 g), similar sweetness (12.4-13.7% Brix), and much lower acidity (1.41 g citric acid/100 g fruit). By comparison, ‘ORUS 2785-2’ has very small fruit (2.6 g) due to its half-wild pedigree, with much higher tartness as a result of its higher acid content (2.54 g citric acid/100 g fruit).
‘Zodiac’ differs from the commercial trailing varieties ‘Columbia Star’ and ‘Black Diamond’ in that it is 7-10 days later ripening. ‘Zodiac’ has similar fruit quality after 7 days in refrigerated storage in plastic clam shell packaging at 4° C. to ‘Columbia’ and higher fruit quality than ‘Black Diamond’. The ‘Zodiac’ fruit are smaller and glossier than ‘Columbia Star’ with a flavor that is slightly less aromatic and characterized more by its sweetness with good sugar/acid balance and an excellent texture that combines firm but not overly tough skin and smooth internal quality with very small seeds. The fruit quality and flavor are better than ‘Black Diamond’. ‘Zodiac’ yields were typically similar to or slightly higher than ‘Columbia’ in trials held in Aurora, Oreg.
