Description

Latin name of the genus and species of the plant claimed: ‘CHARM’ is a new strawberry plant that is Fragaria xananassa Duchesne ex Rozier.

Variety denomination: The new strawberry plant claimed is of the variety denominated ‘Charm’ Fragaria xananassa Duchesne ex Rozier.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar strawberry designated ‘Charm’ and botanically known as Fragaria xananassa Duchesne ex Rozier. This new strawberry cultivar was discovered in Corvallis, Oreg. in June 2001 and originated from a cross between the female parent BC 91-14-31 (unpatented) and the male parent WA 94023-1 (unpatented). The original seedling of the new cultivar was asexually propagated in Benton County Oregon since 2001 by rooting daughter plants from stolons from the mother plant. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimen's of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions.

FIG. 5 shows typical entire and sliced fruit after freezing and thawing.

 DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘Charm’ is based on observations taken from 2004 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. ‘Charm’ has not been observed under all possible environmental conditions. The botanical description of ‘Charm’ was taken from plants one year after establishment in the field. Color terminology follows The Royal Horticultural Society Colour chart. London (R.H.S.) (5th edition, 2007).
