USPP33784P2 - Strawberry plant named ‘NJ09-2-1’ - Google Patents

Abstract

A new and distinct strawberry plant variety of Fragaria ananassa named ‘NJ09-2-1’ is provided, a short day cultivar primarily adapted to the climate and conditions of the eastern United States (USDA Plant Hardiness Zones 5b, 6a 6b, 7a, 7b, 8a and 8b). ‘NJ09-2-1’ has large, long conic to cylindrically shaped fruit, with a medium glossy even surface, a raised calyx with upward sepals, and a medium to broad band without achenes.

Description

Latin name of genus and species of the plant claimed: Fragaria ananassa.

Variety denomination: ‘NJ09-2-1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of strawberry plant named ‘NJ09-2-1’ that resulted from a controlled cross between the female parent ‘NJ6-13-1’ (unpatented) and the male parent ‘NJ03-232-2’ (unpatented) in 2009. Both parental genotypes are derivatives of many cycles of crosses and selection, ‘NJ6-13-1’ was chosen for its large fruit size. ‘NJ03-232-2’ was chosen for the excellent flavor of its fruit. Seeds of the cross were germinated in a greenhouse and planted in the field at a research farm in New Brunswick, N.J. in 2010. Plants were evaluated for two seasons in observational plots. The selected plant designated as ‘NJ09-2-1’ was recognized for its vigor, productivity, and large flavorful fruit. After its selection, ‘NJ09-2-1’ was asexually propagated using stolons for further evaluations in observational and replicated trials in New Jersey and Pennsylvania from 2013 to 2018. ‘NJ09-2-1’ as herein described and illustrated was found to remain true to type through successive generations of asexual production.

BRIEF SUMMARY OF THE INVENTION

‘NJ09-2-1’ is a short day cultivar primarily adapted to the climate and conditions of the eastern United States (USDA Plant Hardiness Zones 5b, 6a 6b, 7a, 7b, 8a and 8b.

‘NJ09-2-1’ has large, long conic to cylindrically shaped fruit, with a medium glossy even surface, a raised calyx with upward sepals, and a medium to broad band without achenes.

‘NJ09-2-1’ is believed to be most closely related to the strawberry variety ‘NJ08-08-6’ (U.S. Plant Pat. No. 27,544) with which it shares the pollen parent ‘NJ03 232 2’ (unpatented). Flowering ‘NJ09-2-1’ and ‘NJ08-08-6’ plants can easily be distinguished by the attitude of their pedicel hair (upwards and horizontal, respectively). ‘NJ09-2-1’ and ‘NJ08-08-6’ fruit differ in size and shape, including as discussed below in the detailed botanical description.

‘NJ09-2-1’ fruit is generally larger and heavier than that of ‘NJ08-08-6’. The shape of ‘NJ09-2-1’ fruit ranges from long conic to cylindrical, while ‘NJ08-08-6’ fruit is conical. Both ‘NJ09-2-1’ and ‘NJ08-08-6’ fruit have excellent flavor. No representations are made with regard to greater resistance or lessened susceptibility to pests or diseases in comparison to ‘NJ08-08-6’.

    • Calyx attachment.—‘NJ09-2-1’ is raised, ‘NJ08-08-6’ is raised; ‘Chandler’ is level.
    • Diameter of calyx in relation to diameter of fruit.—‘NJ09-2-1’ is slightly larger; ‘NJ08-08-6’ is slightly smaller; and ‘Chandler’ is same size.

The weighted average fruit weight range values were observed in five trials conducted in New Jersey between 2014 and 2018, wherein the ‘NJ08-08-6’ was not present in the 2018 trial. The weighted average fruit weight is the total marketable yield (including primary, secondary, and tertiary fruit) divided by the total number of fruits harvested per plot. Total number of fruit harvested per plot was estimated by dividing marketable yield by the average fruit weight (determined on a sample of 20 fruit, or on all fruit if fewer than 20 present) for each harvest, and summing the number of fruit for all harvests.
    • Range of average brix value percentages.—7.6-10.4 for ‘NJ09-2-1’ 7.5-9.6 for ‘NJ08-08-6’; and 7.0-8.5 for ‘Chandler’. The average Brix values were observed in live trials conducted in New Jersey between 2014 and 2018, wherein ‘NJ08 08 6’ was not present in the 2018 trial, and the Brix values were determined on live fruit per variety at three or four harvests.
