Abstract

A new and distinct variety of strawberry plant, herein referred to by its cultivar name, NSG 203, is provided which forms in abundance attractive early-season ripening large, medium red generally conical fruit having firm flesh that is longer than broad in configuration. A medium to high vigor is exhibited. The growth habit is dense, semi-upright and globose. White inflorescence is displayed. Commonly a calyx is displayed which is substantially bigger to the diameter of the corolla when open. The new variety is particularly well suited for the commercial industry.

DETAILED BOTANICAL DESCRIPTION

[0036] The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England, Edition V. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on plants which were reproduced asexually by the use of stolons in open field at Zielona Gora, Poland located at 51 848 N-15 447 E and growing under the cover of plastic tunnels at Nova Siri (MT) Italy located at 4008 40 N-16 39 40 E and 10 meters above sea level.
