Blueberry plant named ‘C95-12’
A new and distinct cultivar of Vaccinium hybrid plant named ‘C95-12’, characterized by its combination of upright to bushy plant shape and strong plant growth vigor, evergreen foliage with medium to late timing of vegetative bud burst, lateness of flowering and fruiting, large berry size with oblate shape, medium to firm fruit suited to handling, attractive dark blue fruit color and small picking scar, strong berry sweetness with medium acidity. This combination results in higher quality fruit with a later availability than other varieties.

Latin name of genus and species of plant claimed: Vaccinium hybrid.
Variety denomination: ‘C95-12’.BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct perennial variety of Vaccinium hybrid (Southern Highbush Blueberry), which has been given the variety denomination of ‘C95-12’. Its market class is that of a fruiting plant. ‘C95-12’ is intended for use as fresh fruit for shipping, customer pick and processing markets and as a home garden plant.
The new Vaccinium hybrid cultivar is a selection resulting from seedlings grown at Corindi Beach, NSW, Australia from seed extracted from fruit produced during a controlled breeding programme of Vaccinium at Gainesville, Fla., USA in 1993 from a cross of seed parent ‘F93-29’ (unpatented) and pollen parent ‘F84-35’ (unpatented). The new cultivar was discovered and selected as a single plant within a population of plants of Vaccinium hybrids in 1995 in a commercial field plantation environment at Corindi Beach, New South Wales, Australia with final selection after confirmation of traits in 1997. Selection criteria was a combination of strong plant growth vigor, lateness of ripening, good fruit flavor, large fruit size, firm fruit suited to handling, attractive dark blue fruit color and small picking scar. The selection was subsequently evaluated for a number of years at the commercial farms at Corindi Beach, New South Wales, Australia.
Asexual reproduction of the new cultivar by cutting propagation since 1995 at Corindi Beach, New South Wales, Australia and has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation. The new variety has been primarily compared to the variety ‘Southern Belle’ (U.S. Plant Pat. No. 13,931). In Corindi Beach, New South Wales, Australia the plant growth habit of ‘C95-12’ is ‘upright to bushy’ whereas the plant growth habit of ‘Southern Belle’ is ‘upright’. The plant growth vigor of ‘C95-12’ is ‘strong to very strong’ whereas the plant growth vigor of ‘Southern Belle’ is ‘weak to medium’. The time of vegetative bud burst of ‘C95-12’ is usually ‘medium to late’ whereas the time of vegetative bud burst of ‘Southern Belle’ is ‘late’. The fully developed leaf length of ‘C95-12’ is ‘medium’ (mean 50 mm) whereas the fully developed leaf length of ‘Southern Belle’ is ‘medium to long’ (mean 57 mm). The fully developed leaf width of ‘C95-12’ is ‘broad’ (mean 34 mm) whereas the fully developed leaf width of ‘Southern Belle’ is ‘medium’ (mean 28 mm). The fully developed leaf attitude of ‘C95-12’ is usually ‘horizontal’ whereas the fully developed leaf attitude of ‘Southern Belle’ is ‘acute’. Corolla ridges are absent on flowers of ‘C95-12’ whereas corolla ridges are present on flowers of ‘Southern Belle’. The time of beginning of flowering of ‘C95-12’ is ‘late to very late’ whereas the time of beginning of flowering of ‘Southern Belle’ is ‘late’. The time of fruit ripening of ‘C95-12’ is ‘late to very late’ whereas the time of fruit ripening of ‘Southern Belle’ is ‘late’. Berry cluster density is dense on ‘C95-12’ whereas berry cluster density is medium on ‘Southern Belle’. The depth of the calyx basin on a berry of ‘C95-12’ is ‘shallow’ whereas the depth of the calyx basin on a berry of ‘Southern Belle’ is ‘medium’. The diameter of the calyx basin on a berry of ‘C95-12’ is ‘very broad’ (mean 9.1 mm) whereas the diameter of the calyx basin on a berry of ‘Southern Belle’ is ‘medium’ (mean 4.9 mm). The sweetness of a berry of ‘C95-12’ is rated as ‘strong’ whereas the sweetness of a berry of ‘Southern Belle’ is rated as ‘weak’. The acidity of a berry of ‘C95-12’ is rated as ‘medium’ whereas the sweetness of a berry of ‘Southern Belle’ is rated as ‘weak’. This combination of fruiting attributes results in ‘C95-12’ being a more suitable variety for commercial and home garden use than ‘Southern Belle’.SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘C95-12’ as a new and distinct cultivar of Vaccinium hybrid plant:
- 1. Upright to bushy plant growth habit
- 2. Strong plant growth vigor
- 3. Medium to late timing of vegetative bud burst
- 4. Late to very late timing of beginning of flowering
- 5. Late to very late timing of fruit ripening
- 6. Dark blue berry color
- 7. Berry firmness is medium to firm
- 8. Picking scar is dry
- 9. Berry diameter is large
- 10. Berry shape in longitudinal cross-section is oblate
- 11. Berry sweetness is strong
- 12. Berry acidity is medium
Plants of the new cultivar differ from plants of the Vaccinium hybrid parents primarily in late to very late timing of beginning of flowering and late to very late timing of berry ripening and large berry diameter combined with strong plant growth vigor whereas the seed parent is mid season in timing of flowering and berry ripening with medium to berry diameter and the pollen parent is medium season in timing of flowering and berry ripening and medium plant growth vigor.
The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘C95-12’.
The following is a detailed botanical description of a new and distinct variety of an Vaccinium hybrid ornamental plant known as ‘C95-12’. Plant observations were made on plants grown in Corindi Beach, New South Wales, Australia. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made from August to October 2007 of mature ‘C95-12’ plants (age 4 years) grown in outdoor field plantings with day temperature ranging from 21° C. to 23° C., night temperatures ranging from 10° C. to 12° C., and light levels ranging from 6 to 8 klux. Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, younger plants. ‘C95-12’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may vary with variations in the environment such as season, temperature, light quality, light intensity, day length, cultural conditions and the like. Color notations are based on The Royal Horticultural Society Color Chart, of The Royal Horticultural Society, London, 2007 edition.
