USPP36894P2 - Grapevine named ‘SV36-25-451’ - Google Patents

Abstract

A new and distinct variety of grapevine plant named ‘SV36-25-451’ particularly characterized by its large, yellow green skinned berries with crisp flesh and muscat flavor and which ripen in late July in the McFarland, California area.

Description

Latin name of the genus and species of the plant claimed: The plant claimed relates to a new and distinct variety of Vitis vinifera L.

Variety denomination: The plant claimed shall be known as ‘SV36-25-451’.

BACKGROUND OF THE INVENTION

The present invention relates a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to as grapevine named ‘SV36-25-451’. As used herein, ‘grapevine’ refers to all plant parts including, vines, canes, tendrils, leaves, fruit and roots of ‘SV36-25-451’. Grapevine named ‘SV36-25-451’ is the result of an effort to produce a mid-season green grape with excellent fruit characteristics. This new cultivar originated from a cross conducted in May 2015 near McFarland, California between female grapevine plant selection ‘SV17-55-220’ (unpatented) and male grapevine plant ‘SV21-66-226’ (U.S. Plant Pat. No. 24,531). Resultant ovules from the cross were harvested 42 days after pollination and cultured on ‘McCown's Woody Plant Medium’. Subsequently, the resultant embryonic plants were cultured in the same medium in the laboratory under twelve hours of light from LED lamps at 29° C. The seedlings from this effort were transplanted to the greenhouse in November of 2015 and grown in the greenhouse at 29° C. with 12 hours illumination under LED lamps. The seedling population of 140 plants was planted in the field in the spring of 2016 near McFarland, California. The new grapevine was selected from this seedling population on Sep. 12, 2018. It was then propagated by cuttings and grafted to ‘Freedom’ (unpatented) rootstock in 2019. The present invention has been found to retain its distinctive characteristics through two successive asexual propagations.

Grapevine named ‘SV36-25-451’ differs from its female parent grapevine ‘SV17-55-220’ in that ‘SV36-25-451’ has large, elliptical shaped, yellow green seedless berries and flowers with functional pollen, whereas ‘SV17-55-220’ has medium sized, elliptical shaped, green seedless berries and flowers that are pistillate.

Grapevine named ‘SV36-25-451’ differs from its male parent ‘SV21-66-226’ in that ‘SV36-25-451’ has berries are elliptical shaped whereas ‘SV21-66-226’ has ovate shaped berries.

Grapevine named ‘SV36-25-451’ most closely resembles commercially available grapevine named ‘Sheegene 17’ (U.S. Plant Pat. No. 28,270) but ‘SV36-25-451’ has berries with a mild, muscat flavor whereas ‘Sheegene 17’ (U.S. Plant Pat. No. 28,270) has berries with a sweet, neutral flavor.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the ripe fruit of this new variety when grown under normal horticultural practices near McFarland, California:

• • a. Yellow green berries.
  • b. Crisp berry texture; and
  • c. Large, muscat-flavored berries.

BRIEF DESCRIPTION OF THE DRAWINGS

This new grapevine is illustrated by the accompanying photographs which show fruit clusters, leaves, canes, and tendrils. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from the seedling vine and from a plant about 4 years-old, grown in a field near McFarland, California in 2022.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘SV36-25-451’. Descriptions of the new invention apply to vines of ‘SV36-25-451’ grown on ‘Freedom’ rootstock at a density of 1,537 vines per hectare grown near McFarland, California in 2022. These vines were in their fourth year of production, having been planted in 2019. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Color references are primarily to The Royal Horticultural Society's Colour Chart, The Royal Horticultural Society, London, United Kingdom. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
