Strawberry plant named ‘Sweet Sunrise’

Abstract

This invention relates to new and distinct cultivar of strawberry plant named ‘Sweet Sunrise’. The new cultivar is primarily characterized by its early ripening and its medium-large, conical fruit that have outstanding processing characteristics including deep red internal and external color, sweet flavor, and very easy calyx removal, as well as vigorous, productive plants that are tolerant to biotic and abiotic stress.

Description

Latin name of the genus and species of the plant claimed: ‘SWEET SUNRISE’ is a new strawberry plant that is Fragaria×ananassa Duchesne ex Rozier.

Variety denomination: The new strawberry plant claimed is of the variety denominated ‘Sweet Sunrise’, Fragaria×ananassa Duchesne ex Rozier.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar strawberry designated ‘Sweet Sunrise’ and botanically known as Fragaria×ananassa Duchesne ex Rozier. This new strawberry cultivar was discovered in Corvallis, Oreg. in June 2000 and originated from a cross between the female parent ‘Puget Reliance’ (U.S. Plant Pat. No. 9,310) and the male parent B 754 (unpatented). The original seedling of the new cultivar was asexually propagated by rooting daughter plants from the mother plant since 2000 in Benton County, Oreg. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘Sweet Sunrise’ is based on observations taken from 2002 to 2012 growing seasons in trials in Corvallis and Aurora, Oreg. This description is in accordance with UPOV terminology. Color designations, color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘Sweet Sunrise’ has not been observed under all possible environmental conditions. The botanical description of ‘Sweet Sunrise’ was taken from plants one year after establishment in the field. Color terminology follows The Royal Horticultural Society Colour chart. London (R.H.S.) (5^th edition, 2007).

COMPARISON WITH PARENTAL GENOTYPES

When ‘Sweet Sunrise’ is compared to female parent ‘Puget Reliance’ (U.S. Plant Pat. No. 9,310), the fruit are deeper red, firmer, and more conically shaped and the plants less susceptible to foliar disease. When ‘Sweet Sunrise’ is compared to the male parent B 754 (unpatented) the fruit are deeper red, firmer and the plants better adapted to biotic and abiotic stress in the Pacific Northwest.
