Description

Latin name of the genus and species: The Latin name of the novel strawberry plant disclosed herein is Fragaria x ananassa Duchense.

Variety denomination: The inventive strawberry variety has been given the variety denomination ‘NCS 10-156’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of strawberry (Fragaria x ananassa Duchense) named ‘NCS 10-156’. This strawberry plant (genotype) originated in a strawberry breeding plot in Salisbury, N.C. The genotype was collected from open pollinated fruit from the seed parent ‘NCH 05-73P’. The seed parent is an unreleased breeding selection from a cross that was made to improve the university's strawberry breeding program genepool. The seeds collected from the female parent in the spring of 2009 were germinated in the summer and planted in the fall of 2009. The selection was made in the spring of 2010. ‘NCS 10-156’ was first asexually propagated at the Piedmont Research Station, Salisbury N.C., Rowan County, in 2011. Ten daughter plants were propagated from runner tips originating from the mother plant and transplanted to second test trials where they were compared to several other genotypes in 2011. Plants were established in replicated trials in 2012-17. ‘NCS 10-156’ exhibited early fruit production with excellent taste in multiple locations and years. Propagules of ‘NCS 10-156’ in all trials have been identical to the initial daughter plants. The combination of traits disclosed herein that characterize ‘NCS 10-156’ have been retained true to type through successive cycles of asexual propagation.

SUMMARY OF THE INVENTION

‘NCS 10-156’ when grown in the piedmont regions of North Carolina consistently produced fruit early in the season with excellent flavor (Tables 1 and 2, FIG. 3). Yields of NCS 10-156 are higher than ‘Sweet Charlie’ (U.S. Plant Pat. No. 8,729), the standard early producing cultivar in North Carolina. Fruit of ‘NCS 10-156’ has higher soluble solids than ‘Camarosa’ (U.S. Plant Pat. No. 8,708) and ‘Chandler’ (U.S. Plant Pat. No. 5,262), which gives it a very sweet flavor. ‘Sweet Charlie’, ‘Camarosa’ and ‘Chandler’ are the most commonly planted standard cultivars used by the strawberry industry in North Carolina at this time. ‘NCS 10-156’ is considered a short day plant which means flowering occurs one time during the season. ‘NCS 10-156’ begins to flower during week 9-10 and fruit ripening begins week 14-15, the duration of the flowering and fruiting periods are 4 to 8 weeks depending on the season. Preferred planting date is 25 September in Salisbury, N.C. and 5 October in Clayton, N.C. The shelf life of ‘NCS 10-156’ is short, therefore it is suitable for pick your own and local markets. Nursery performance has been very good in western NC locations due to abundant production of many runners that produce multiple daughter plants that root easily. Yield data of the parents of ‘NCS 10-156’ is not available. The new and distinct variety of strawberry Fragaria x ananassa Duchense ‘NCS 10-156’ has the following unique combination of desirable features that are outstanding in a new variety including (1) early ripening, (2) yields higher than the current early season cultivar ‘Sweet Charlie’, and (4) excellent flavor.

 DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a new distinct strawberry variety known as ‘NCS 10-156’. The description is based on observations taken from the 2014-2017 growing seasons in Clayton, N.C. and Salisbury, N.C. The plants are set in the fall and fruiting occurs in the following spring. This description is in accordance with International Union for the Protection of New Varieties of Plants (UPOV) terminology. Color designations and descriptions and other phenotypical traits may deviate from the stated values depending on location and season as this genotype has not been observed in all environmental conditions.
