Abstract
A new and distinct Actinidia chinensis cultivar named ‘W45’ is disclosed, characterized by having distinctive yellow/green flesh fruit and a season harvest time of Mid-April. Additionally, the new variety produces fruit with very soft, slight pubescence and with a distinctive blunt stylar end shape and square shoulders. The new variety is suitable for commercial production of kiwi fruit.
Description
Latin name of the genus and species: Actinidia chinensis.
Variety denomination: ‘W45’.
The new cultivar is a product of a planned breeding program, begun in 1975 under the direction of the inventor, Donald Alfred Skelton, a citizen of New Zealand. The seed parent is the unpatented, proprietary seedling variety referred to as Actinidia chinensis ‘R55’ The pollen parent is the unpatented, proprietary seedling variety referred to as Actinidia chinensis ‘CMW85 .’
Fruit of the new variety was first evaluated in 2001 with favorable results. After the first evaluation, semi-hardwood cuttings were made of ‘W45’ and were grafted onto 5 seedling rootstocks 3; of A. chinensis and 2 of A. deliciosa. Evaluation, asexual propagation and grafting all first took place at the inventor's commercial nursery in Rangiriri, New Zealand in 2001. Subsequent evaluations of the variety have shown the characteristics to be true to type.
The cultivar ‘W45’ 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 ‘W45’ These characteristics in combination distinguish ‘W45’ as a new and distinct Actinidia chinensis cultivar:
-
- 1. Distinctive yellow/green flesh fruit
- 2. Seasonal harvest time of mid April
- 3. Very soft, downy pubescence on fruit, with weak adherence to the fruit skin.
- 4. Widely obovate fruit shape.
- 5. Fruit with a distinctive blunt stylar end shape and square shoulders.
Plants of the new cultivar ‘W45’ are similar to plants of the seed parent, Actinidia chinensis ‘R55’ in most horticultural characteristics, however, plants of the new cultivar ‘W45’ produce larger size fruit, of a more greenish hue. Additionally, the new variety has new foliage emerging typically six weeks earlier than ‘R55.’
Plants of the new cultivar ‘W45’ are similar to plants of the pollen parent, Actinidia chinensis ‘CMW85’ in most horticultural characteristics, however, plants of the new cultivar ‘W45’ produce significantly more female flowers than the male parent. Whereas the new cultivar produces large quantities of female flowers, the male parent produces almost no viable female flowers.
The new variety is best compared to the commercial variety, ‘Hort16A,’ U.S. Plant Pat. No. 11,066. ‘W45’ is similar to ‘Hort16A’ in many horticultural characteristics, however, ‘W45’ produces fruit with yellow/green flesh coloration whereas ‘Hort16A’ produces fruit of a golden yellow. Additionally, the new variety produces a widely obovate shaped fruit, compared to ovoid. Fruit of the new variety ‘W45’ are distinctively blunt on the stylar end, compared to the strong pointed stylar end shape of ‘Hort16A.’ Fruit shape differences can also be noted in the shoulder shape. Whereas ‘W45’ produces fruit with strongly squared shoulder, ‘Hort16A’ fruit have rounded shoulders.
The accompanying photograph in FIG. 1 illustrates in full color typical foliage and flowers on plants of ‘W45.’
All photographs were taken of an approximately 7 year old plant. 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.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘W45’ plants grown under outdoor commercial trial conditions in Rangiriri New Zealand. The growing temperature ranged from 10° C. to 25° C. with no precipitation. Measurements and numerical values represent averages of typical plant types.
