USPP25331P3 - Actinidia chinensis plant named ‘X264’ - Google Patents

Abstract

A new and distinct Actinidia chinensis cultivar named ‘X264’ is disclosed, characterized by having distinctive yellow flesh fruit, and an early seasonal harvest time. Additionally, the new variety produces oblong fruit with weak skin adherence to flesh and with a distinctive blunt, slightly protruding 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: ‘X264’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program under the direction of the inventor, Donald Alfred Skelton, a citizen of New Zealand. The seed parent is the unpatented, proprietary variety referred to as Actinidia chinensis ‘A50’. The pollen parent is the unpatented, proprietary seedling variety referred to as Actinidia chinensis ‘A28’.

Fruit of the new variety was first evaluated in 2001 with favorable results. After the first evaluation, semi-hardwood cuttings were made of ‘X264’ and were grafted onto seedling rootstocks of A. deliciosa. Evaluation, asexual propagation and grafting all first took place at a research nursery in North Waikato, New Zealand. Subsequent evaluations of the variety have shown the characteristics to be true to type.

SUMMARY OF THE INVENTION

The cultivar ‘X264’ 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 ‘X264’ These characteristics in combination distinguish ‘X264’ as a new and distinct Actinidia chinensis cultivar:

• • 1. Oblong shaped fruit form
  • 2. Heavy fruit weight, similar to the known variety ‘Hayward’.
  • 3. Weakly blunt protruding stylar fruit end.
  • 4. Yellow flesh fruit
  • 5. early season fruit harvest
  • 6. Weak adherence of fruit skin to flesh
  • 7. Weak adherence of hair to fruit skin

COMMERCIAL COMPARISON

The new variety is best compared to the commercial variety, ‘Hort16A’ U.S. Plant Pat. No. 11,066. ‘X264’ is similar to ‘Hort16A’ in many horticultural characteristics, however, ‘X264’ produces mature fruit approximately 2 to 4 weeks earlier in the season than ‘Hort16A’. Additionally, fruit of the new variety ‘X264’ has a weakly protruding stylar end, compared to the strongly protruding stylar end of ‘Hort16A’.

The new variety can be compared to the commercial variety, ‘Hayward’, unpatented. ‘X264’ is similar to ‘Hayward’ in many horticultural characteristics, however, ‘X264’ produces mature fruit several weeks earlier in the season than ‘Hayward’. Additionally, ‘X264’ has an interior fruit coloration with a stronger yellow tone.

The new variety is similar to the seed parent variety in some horticultural characteristics. However, the new variety differs in the following;

• • 1. The new variety has a early-season bud set, compared to the late-season bud set of the seed parent.
  • 2. The new variety flowers earlier than the seed parent variety.
  • 3. Fruit of the new variety can be harvested earlier than fruit of the seed parent variety.

The new variety can be compared to the pollen parent variety, however, the plants clearly differ, as the new variety is a fruit producing female plant and the pollen parent is a non-fruiting male plant. The new variety differs in the following;

• • 1. No fruit is produced by the pollen parent.
  • 2. The new variety sets buds and flowers slightly earlier than the pollen parent.
