Abstract

A kiwifruit plant particularly distinguished by pale yellow fruit flesh with red color radiating from the axial ovary, cylindrical fruit shape with a circular cross section and slightly blunt protruding stylar end, mid-season fruit maturity and an average fruit weight of 104 grams is described.

Description

Genus and species: Actinidia chinensis.
Variety denomination: ‘Yang's Golden Red No. 50’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Actinidia chinensis (kiwifruit) hereinafter referred to by the cultivar name ‘Yang's Golden Red No. 50’ or the ‘new plant’. ‘Yang's Golden Red No. 50’ was selected from a population of seedlings derived from crossing two kiwifruit selections ‘Hongyang’ (U.S. Plant patent application Ser. No. 11/645,130—now abandoned), the female, and ‘Male No. 13’ (unpatented), the non-fruiting male, using controlled pollination in the course of a planned kiwifruit variety breeding program. The new plant was selected on 9 Sep., 2004 at Huaisi Town, Yangzhou, China.
The new plant has been asexually propagated by grafting and the unique combination of characteristics of the new plant has been found to be reproducible and stable in successive generations of propagation. In order to obtain true-to-type clones of the initial plant, asexually propagated plants were obtained by grafting dormant buds from the original seedling onto Actinidia deliciosa rootstock.
Plant Variety Rights application for ‘Yang's Golden Red No. 50’ was filed in China on 9 Jan., 2012 and assigned the application number 20120001.1. Propagation material of ‘Yang's Golden Red No. 50’ has never been sold or made publically available prior to the filing of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of the new plant when grown under normal horticultural practices in Huaisi Town, Yangzhou, China:
    • 1. Pale yellow fruit flesh with red color radiating from the axial ovary
    • 2. Cylindrical fruit shape with a slightly blunt protruding stylar end
    • 3. Mid-season maturing fruit
    • 4. Average fruit weight of 104 grams
DESCRIPTION OF THE PHOTOGRAPHS
The new plant is illustrated by the accompanying photographs which show in full color typical specimens of the plant habit, foliage, fruit and flowers of the new variety ‘Yang's Golden Red No. 50’. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs include plants approximately nine years after grafting onto Actinidia deliciosa ‘Hayward’ (unpatented) rootstock in optimum conditions in Huaisi Town, Yangzhou, China.

FIG. 3 shows typical whole fruit and cross section in the studio
FIG. 4 shows typical fruit cross section and longitudinal section in the studio
FIG. 5 shows flowers on the vine
FIG. 6 shows flowers in the studio
DESCRIPTION OF THE NEW CULTIVAR
The following detailed description sets forth the distinctive characteristics of ‘Yang's Golden Red No. 50’. The following observations, measurements and values were made on nine year old vines grafted onto ‘Hayward’ (unpatented) rootstock, and managed under standard orchard practice in Huaisi Town, Yangzhou, China. Random measurements of each characteristic were obtained from a sample of 50 plants unless otherwise stated.
Horticultural terminology is used in accordance with UPOV guidelines for kiwi. All dimensions are in millimeters, and all weights are in grams (unless otherwise stated). Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (e.g., light, temperature and moisture), nutrient availability, rootstocks, or other factors. Color readings were taken in natural light. Color references are primarily to the Fourth edition, 2001 of The Colour Chart published by The Royal Horticultural Society, London (R.H.S.), except where general colours of ordinary significance are used.
