Abstract

A new and distinct kiwifruit variety is disclosed. The variety results from selection among a population of seedlings derived from crossing the kiwifruit selections known as ‘Al7’ (not patented) and ‘R4’ (not patented). The fruit of the plant of this new kiwifruit variety is characterized by its internal medium-yellow color. The new kiwifruit variety has been named ‘Y374.’

Description

Latin name of the genus and species of the plant claimed: Actinidia chinensis.
Variety denomination: ‘Y374’.
BACKGROUND AND SUMMARY OF THE INVENTION
The invention relates to the discovery and asexual propagation of a new and distinct variety of kiwifruit, Actinidia chinensis ‘Y374’, as herein described and illustrated. The new kiwifruit variety ‘Y374’ was selected from a population of seedlings derived from crossing two kiwifruit selections A17 (unpatented), the female, and R4 (unpatented), the non-fruiting male, using controlled pollination in the course of a planned kiwifruit variety breeding program. The cross was made in October 1999 by Donald Alfred Skelton at Rangiriri, New Zealand.
The new kiwifruit variety ‘Y374’ may be distinguished from its parent, A17, in that A17 has flat sided fruit, while the fruit of ‘Y374’ is rounded, A17 has a strongly sharp protruding stylar end, while the fruit of ‘Y374’ has a rounded to slightly blunt protruding stylar end, and A17's fruit matures late in the season, while the fruit of ‘Y374’ matures medium early (i.e., late March to May in New Zealand). The new kiwifruit variety ‘Y374’ may be distinguished from its parent, R4, in that R4 is a non-fruiting male while ‘Y374’ is a fruit-bearing female. In addition, R4 has bark of a Greyed-green color (RHS 193B), while ‘Y374’ has bark colored Grey-brown (RHS 199B). The new kiwifruit variety ‘Y374’ may be distinguished from presenhtly available cultivars such as, for example, Actinidia chinenis variety ‘Hort16A’ (U.S. Plant Pat. No. 11,066), by the following distinguishing characteristics: the fruit of the new kiwifruit variety ‘Y374’ matures earlier than the fruit of ‘Hort16A’, and the fruir of the new kiwifruit variety ‘Y374’ expresses a medium-yellow flesh color.
The new kiwifruit variety ‘Y374’ may be distinguished from other presently available kiwifruit varieties featuring medium-yellow flesh fruit such as, for example, ‘Y363’ (unpatented), ‘D15’ (unpatented), ‘X273’ (unpatented), and ‘Skelton A19’ (unpatented), by the following distinguishing characteristics: the fruit shape of the new variety ‘Y374’ is obovoid compared with that of ‘Y363’, which is oblong. The fruit size of the new variety ‘Y374’ is large compared with that of ‘D15’, which is medium, and ‘X273’, which is small. Furthermore, the beak of the new variety ‘Y374’ is very small compared with that of ‘Skelton A19’, which is apparent.
Asexual propagation of the new kiwifruit variety ‘Y374’ by grafting, in Rangiriri, New Zealand, shows that the unique combination of characteristics of the variety come true to form and are established and transmitted through succeeding 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 chinensis and Actinidia deliciosa rootstocks.

 DETAILED BOTANICAL DESCRIPTION OF THE INVENTION
The following is a detailed description of the new variety. The specimens described were grown at Rangiriri, New Zealand. The observations were made in the 2005 to 2008 seasons on vines grafted onto Chinensis and Deliciosa rootstocks, and managed under standard orchard practice. Random measurements of each characteristic were obtained from samples of 6 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, moisture), nutrient availability, rootstocks, or other factors. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color names beginning with a capital letter designate values based upon the R.H.S. Colour Chart published by the Royal Horticultural Society, London, England.
PLANT AND FOLIAGE

The general fruit shape in longitudinal section is obovoid, with the general shape of the fruit stem end being rounded (FIG. 2A), and with the general shape of the stylar end also being rounded (FIGS. 1 and 2B). The calyx ring is strongly expressed.
The fruit skin has few fruit hairs and no lenticels. The fruit skin is medium Yellow-green in color (RHS 146C) and has average to lesser adherence of skin to flesh. The inner pericarp is colored medium Yellow (RHS 4C) at maturity for consumption. The fruit average approximately 16% Brix at maturity for consumption. The average size of the fruit core is about 15 mm by about 70 mm and is White (RHS 155C) in color.
