Strawberry plant named ‘FL 16.30-128’

Abstract

A new and distinct variety of strawberry (Fragaria X ananassa), which originated from seed produced by a hand-pollinated cross between ‘FL 13.27-142’ and ‘FL 12.90-53’. The new strawberry, named ‘FL 16.30-128’, can be distinguished at least by its exceptional conical fruit shape; exceptional sweetness and flavor; and high soluble solids content when grown in West Central Florida or other regions that have a climate similar to that of West Central Florida.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) ‘FL 16.30-128’ is illustrated by the accompanying photograph that shows 5 month-old specimens. The colors shown are as true as can be reasonably captured by conventional photographic procedures. The photograph was captured in February of 2020 in West Central Florida.

(2) FIG. 1. Shows 5-month-old whole plants, including foliage, and fruit at varying stages of ripeness.

DETAILED BOTANICAL DESCRIPTION

(3) The following detailed botanical description sets forth the distinctive characteristics of ‘FL 16.30-128’. The present botanical description is of ‘FL 16.30-128’ when grown under the ecological conditions that prevail during the winter production season in Balm, Fla., i.e., warm days and cool nights. The plant was 5 months of age when the data was collected. Colors are objectively described using the CIELAB color scale (originally published by the International Commission on Illumination (CIE) in 1976) as measured using a Minolta Chroma Meter CR-400 (Minolta, Ramsey, N.J.) colorimeter with a 1 cm aperture, calibrated against a white tile (Y=85.5, x=0.3164, y=0.3237). When the CIELAB color designations differ from the accompanying photographs, the CIELAB color designations are accurate.
