plant named ‘Winter Bell’

A new and distinct Vaccinium spp. cultivar named ‘WINTER BELL’ is disclosed, characterized by a semi-upright plant habit, vigorous growth and semi-deciduous habit in Florida. The new variety shows tolerance for wetter soil conditions. Fruit yield is exceptionally high, with fruit ripening early, with first harvest in mid to late March. Fruit is somewhat bell-shaped with good size and an attractive waxy coating. The new variety is a Vaccinium, and is normally used as an ornamental garden or landscape plant.

Description

Latin name of the genus and species: Vaccinium spp.

Variety denomination: ‘WINTER BELL’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as the product of a breeding program conducted in Winter Haven, Fla., by the breeder David Weber. ‘Winter Bell’ was selected from open pollinated seedlings of the undistributed, unpatented variety referred to by code FL 95-174 which were planted in Winter Haven, Fla. in June, 2008. The pollen parent is unknown. Due to its earliness and fruit quality ‘Winter Bell’ was selected for yield evaluation in 2012. ‘Winter Bell’ was evaluated as a single plant test against other commercial varieties in 2012 and 2013 and planted in a confidential, controlled field test plot in June, 2013.

‘Winter Bell’ has been asexually propagated over numerous generations by softwood cuttings in Winter Haven, Fla., and all propagated material has retained the vegetative and fruit characteristics of the mother plant. First asexual propagation was performed June 2012, in Winter Haven, Fla. at a commercial nursery.

Asexual reproduction of the new cultivar ‘WINTER BELL’ by vegetative cuttings was performed at the nursery in Hawthorne, Fla. in September of 2007. Vegetative reproduction by cuttings has produced multiple generations, and has shown that the unique features of this cultivar are stable and reproduced true to type through successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘WINTER BELL’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WINTER BELL’. These characteristics in combination distinguish ‘WINTER BELL’ as a new and distinct Vaccinium spp. cultivar:

    • 1. Exceptionally high fruit yield.
    • 2. Early fruit ripening, first harvest in mid to late March.
    • 3. Vigorous growth in native spodic soils.
    • 4. Excellent fruit bloom (attractive waxy coating).
    • 5. Excellent fruit size.
    • 6. Excellent fruit scar.
    • 7. Resistance to common root diseases, tolerating wetter soils.
    • 8. Semi-evergreen to evergreen habit under Florida conditions.
    • 9. Slight bell shape to fruit.
    • 10. Semi-upright habit.
    • 11. Fruit of average firmness.

PARENT COMPARISON

Plants of the new cultivar ‘WINTER BELL’ are similar to plants of the parent variety in most horticultural characteristics. However, plants of the new cultivar ‘WINTER BELL’ differ from FL 95-174 in the following:

    • 1. ‘Winter Bell’ has larger leaves.
    • 2. ‘Winter Bell’ produces larger fruit.
    • 3. Plants of ‘Winter Bell’ are more upright with less lateral branching.
    • 4. Plants of ‘Winter Bell’ grow more vigorously.
    • 5. Fruit of ‘Winter Bell’ has a different shape.
    • 6. Fruit occurs in loose clusters on ‘Winter Bell’, whereas fruit occurs on the parent variety more singularly along stem internodes.
    • 7. Fruit pedicels of ‘Winter Bell’ are longer.

The pollen parent is unknown.

COMMERCIAL COMPARISON

‘WINTER BELL’ can be compared to the commercial variety Vaccinium ‘Jewel’ U.S. Plant Pat. No. 11,807. Plants of the new variety are similar to ‘Jewel’ in most horticultural characteristics, however, ‘WINTER BELL’ differs in the following:

    • 1. Earlier ripening than Jewel. In testing conducted during 2012, by March 20, ‘Winter Bell’ produced 2.9 pounds of fruit whereas ‘Jewel’ produced had produced 0.28 pounds of fruit.
    • 2. Plants of ‘Winter Bell’ are grow more vigorously.
    • 3. Highly waxy leaves of ‘Winter Bell’ are more durable to physical stress.
    • 4. Plants of ‘Winter Bell’ yield more fruit.
    • 5. Fruit of ‘Winter Bell’ has a different shape.
    • 6. Leaves are more persistent and rust resistant than foliage of ‘Jewel’.

‘WINTER BELL’ can be compared to the commercial variety Vaccinium ‘Emerald’ U.S. Plant Pat. No. 12,165. Plants of the new variety are similar to ‘Emerald’ in most horticultural characteristics, however, ‘WINTER BELL’ differs in the following:

    • 1. Earlier ripening than ‘Emerald’. In testing conducted during 2012, by March 20, Winter Bell produced 2.9 pounds of fruit whereas ‘Emerald’ had no ripe fruit on this date. The subsequent measurement, March 27, resulted in 4.7 pounds total harvested to date from ‘Winter Bell’ and 2.9 pounds harvested to date from ‘Emerald’.
    • 2. Plant habit of ‘Winter Bell’ is more upright.
    • 3. Plants of ‘Winter Bell’ are more tolerant of wet soils.
    • 4. Leaves of ‘Winter Bell’ are more waxy.
    • 5. Stronger waxy coating of fruit, giving an attractive, cloudier blue coloration.

OTHER CHARACTERISTICS

  • Disease resistance: Higher than average resistance to normal foliar diseases normal to Vaccinium, have been observed in this variety. Typical foliar pathogens of Vaccinium include Alternaria tenuissima, and Septoria species. Southern high-bush types are more susceptible to Xylella fastidiosa. The new variety appears more resistant to these varieties of foliar pathogens. Resistance to disease found in wet soil conditions also observed. The most common disease found in poorly drained soil is Phytophthora cinnamomi, the new variety is likely to have resistance to this pathogen.
  • Pest resistance: Neither resistance nor susceptibility to the normal pests of Vaccinium.
  • Drought tolerance and temperature tolerance: Low temperature tolerance and drought tolerance have not been tested.
