USPP24465P3 - Citrus reticulata plant named ‘WG3’ - Google Patents

Abstract

A new and distinct Citrus reticulata cultivar named ‘WG3’ is disclosed, characterized by having distinctive fruit that peels easily and dry and can be eaten with little mess. It also has very low seed average of less than 2 seeds per fruit. Additionally, the new variety produces fruit that does not pull very much when ripe until overripe and maintains acid during ripening.

Description

Latin name of the genus and species: Citrus reticulata.

Variety denomination: ‘WG3’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned crossing program in 2001 under the direction of the inventor, Bill Roe, a citizen of The United States. The parents are unnamed proprietary seedlings of Citrus reticulata.

This new variety was found in November 2006 in a commercial nursery in Winter Haven, Fla. Plants were first propagated by tissue culture in 2006 and subsequently grafted onto rootstocks US-897 and US-942. Development, evaluation, tissue culture and grafting all first took place at the inventor's commercial nursery in Winter Haven, Fla. USA. Subsequent evaluations of the variety have shown the characteristics to be true to type.

SUMMARY OF THE INVENTION

The cultivar ‘WG3’ 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 ‘WG3’ These characteristics in combination distinguish ‘WG3’ as a new and distinct Citrus reticulata cultivar:

• • 1. Peel is removed easily.
  • 2. Very low seed production, average less than 2 per fruit.
  • 3. Peel does not pull away from fruit significantly until overripe.
  • 4. Acidity maintained during ripening.
  • 5. Can be peeled and eaten without a mess.
  • 6. Peel is dry.
  • 7. Very little albedo.

COMPARISON TO PARENTS

Plants of the new cultivar ‘WG3’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘WG3’ produce fruit with significantly less seeds. Compared to the pollen parent, ‘WG3’ produces firmer fruit. Fruit of ‘WG3’ has less acid than the pollen parent and when peeled, is overall cleaner.

COMMERCIAL COMPARISON

The new variety is best compared to the commercial variety, ‘Dancy,’ unpatented. ‘WG3’ is similar to ‘Dancy’ in many horticultural characteristics, however, ‘WG3’ produces fruit with significantly less seeds, of more uniformed color as well as firmer. Additionally, fruit of the new variety ‘WG3’ are distinctively less susceptible to fungi and its peel pulls away from the fruit less than ‘Dancy’.

‘WG3’ can also be compared to ‘Sunburst’, unpatented. The two varieties are similar in many horticultural characteristics, however ‘WG3’ produces fruit that is not as deep orange in external color and possesses a smoother peel that peels easier and cleaner, with less albedo. Compared to ‘Sunburst’, ‘WG3’ possesses fruit that has much lower seed count, and matures slightly later.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color examples of typical fruit harvested from ‘WG3’.

FIG. 2 illustrates in full color typical foliage of ‘WG3’.

Photographs are taken of plants approximately 3 years old. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
