Description
Latin name and variety denomination: The present invention relates to a new and distinct variety of Vaccinium corymbosum, which is hereby denominated ‘Huron.’
The present invention relates to a new and distinct variety of highbush blueberry plant, denominated ‘Huron.’ ‘Huron’ is a new blueberry cultivar of primarily Vaccinium corymbosum from the Michigan State University breeding program. The rest of its parentage is from V. darrowii (12.5%) and V. angustifolium (3.15%). It is a productive, early ripening cultivar with very high fresh market quality and a long storage life. It is intended for areas where northern highbush cultivars are grown successfully. Plants of ‘Huron’ are vigorous and upright. Canes are numerous, moderately branched and the fruit are well exposed. Its berries are moderately large, have small, dry picking scars, medium blue color, excellent firmness and superior flavor, if allowed to fully ripen. The size of the fruit is unusually regular and is presented in a loose cluster.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following is a detailed botanical description of the new and distinct variety of blueberry denominated ‘Huron,’ its flowers, fruit and foliage. The original selection of ‘Huron’ was evaluated at the Southwest Michigan Research and Extension at Benton Harbor, Mich. for ten years. Hardwood cuttings were also set in a replicated design with 26 other Michigan State University selections at Grand Junction, Mich., South Haven, Mich., Lacota, Mich., Corvallis, Oreg., and Lowell, Oreg. The plantings in Michigan were evaluated for seven years, while the plantings in Oregon were evaluated for two years.
The first harvest of ‘Huron’ falls between the most widely grown early cultivar ‘Duke’ and the most important midseason ones, ‘Draper’ and ‘Bluecrop’. ‘Huron’ has larger fruit than ‘Bluecrop’ and ‘Duke’, as well as a longer shelf life. It is a little smaller fruited than ‘Draper’ with slightly darker fruit, but its fruiting season is earlier. ‘Draper’ is described in “Blueberry plant denominated ‘Draper,’” U.S. Plant Pat. No. 15,103 to Hancock, which was filed on Jan. 23, 2003 and issued Aug. 24, 2004, the disclosure of which is incorporated herein by reference.
Emasculated flowers of MU-6566, the male parent (i.e., the seed parent), were pollinated in 1991 with pollen from G-344U, the female parent. The seeds were germinated, grown in a greenhouse for 1 year and then field planted at the Southwest Michigan Research and Extension Center (SWMREC) in Benton Harbor, Mich. ‘Huron’ was selected from a group of 87 siblings in 1997.
MU-6566 [MU-22 (‘Ashworth’בBluecrop’)×MU-13 (‘Ashworth’בEarliblue’)] originated from the USDA/ARS collaborative breeding program. It was originally selected at Jonesboro, Me. and evaluated later at Grand Junction, Mich. for 6 years. It had an unusually late flowering date for an early genotype and very high yields, but its fruit were dark and weak flavored. G-344 [US 75 (‘Bluecrop’×V. darrowii Fla 4b)×Elizabeth)], also came from the USDA/ARS collaborative breeding program and was originally selected in Hammonton, N.J. It was later evaluated at Grand Junction, Mich. for 10 years. The fruit of G-344 were firm, powder blue with a pleasant, complex flavor, but many of its flower buds were damaged by winter cold, presumably due to a high contribution (25%) of the native southern species, V. darrowii, in its ancestry.
‘Huron’ is moderately self-fertile but requires' pollination from another highbush blueberry cultivar for maximum fruit development.
‘Huron’ may be propagated by hardwood cuttings in a greenhouse and then planted in the field. Initiation of root development from hardwood cuttings may take about four to six weeks. In addition, ‘Huron’ may be propagated by rooted softwood cuttings. Furthermore, generation of micro-shoots in a greenhouse using established tissue culture methods may be used to produce plants of ‘Huron.’
Initiation of root development from microshoots takes about three to four weeks. Such methods are discussed in the following references: Doran, W. L. and Bailey, J.

Consistent high yields at multiple sites in Michigan indicate that the buds and wood of ‘Huron’ are tolerant to fluctuating late fall and spring temperatures. It is exceptionally late flowering and was one of the few early to mid-season genotypes to survive a late frost in the mid-1990s. ‘Huron’ also has excellent winter hardiness, as it has routinely been challenged with mid-winter temperatures below −20° C.
In the trials conducted in Michigan at Grand Junction, ‘Huron’ was consistently one of the top rated advanced selections. It had among the highest fruit load of any of the early to midseason cultivars and the best flavor, as illustrated in Tables 2, 3, and 5. The average date of first harvest was 5 days before ‘Draper’ and six days after ‘Duke’. The fruit of ‘Huron’ was slightly softer than ‘Draper’ and much firmer than ‘Bluecrop’ and ‘Duke’. ‘Huron's’ fruit were smaller than ‘Draper’, but larger than ‘Duke’ and ‘Bluecrop’. Its fruit color was similar to ‘Duke’, but a little darker than ‘Bluecrop’ and ‘Draper’. ‘Huron’ fruit had a storage life as long as ‘Draper’, which was several weeks longer than ‘Duke’ and ‘Bluecrop,’ as illustrated in Table 4. ‘Huron’ had the second highest levels of soluble solids next to ‘Draper’ and the second lowest acidity next to ‘Duke’. The evaluations done at Lacota and South Haven were informal, but generally mirrored the observations made at Grand Junction.
In the trials conducted in Oregon, ‘Huron’ was superior to all but a few of the advanced selections. However, its yields were not as high as in Michigan and its fruit were a little softer and smaller. Its fruit flavor and firmness was superior to ‘Bluecrop,’ but not ‘Draper.’ ‘Draper’ and ‘Bluecrop’ also had higher yields than ‘Huron’.

| TABLE 4 |
| Chemical and physical measurements of the fruit of ‘Duke’, |
| ‘Huron’, ‘Draper,’ and Bluecrop’ harvested in Grand Junction |
| Michigan in 2006 and 2007. Five fruit samples were evaluated for |
| soluble solids (SS), titratable acidity (TA) and firmness (g/mm). |
| Storage life was calculated as the number of weeks that the |
| majority of fruit remained firm at 5° C. |

| TABLE 5 |
| Mean fruit ratings of ‘Draper,’ ‘Huron,’ and ‘Bluecrop’ at |
| Lowell and Corvallis, OR from 2001-2002. Two-year-old plants were |
| set in 2000 at 4 × 10′ spacing with 26 other Michigan State University |
| selections. Evaluations were made when the bushes were 50% ripe. |
| All values were similar in the two years. |

Blueberry growers in Michigan and the cooler production regions across the USA, Europe, and Canada will find ‘Huron’ desirable as a new early northern highbush variety. However, some fruit pedicles of ‘Huron’ fruit remain attached in very hot weather. The fruit of ‘Huron’ also develops sugar slowly and if picked too early can be very tart. In addition, the fruit clusters of ‘Huron’ are relatively tight, which may reduce picking efficiency.
