Abstract

A new and distinct variety of strawberry (Fragaria×ananassa), which originated from seed produced by a hand-pollinated cross between ‘FL 05-107’ and ‘FL 02-58’. The new strawberry, named ‘Florida127’, is distinguished by its ability to produce consistently high yields of large and moderately firm, brightly colored fruit that are exceptionally sweet in flavor when grown in west central Florida or other areas that have a subtropical climate similar to that of west central Florida.

Description

Description

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

Variety denomination: ‘Florida127’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of strawberry (Fragaria×ananassa Duchesne) plant named ‘Florida127’. This new strawberry plant is distinguished by its ability to produce high early and total yields of fruit that are exceptionally and consistently large and sweetly flavored when grown in west central Florida. Asexual propagation was performed at Balm, Fla. where the selection was made and plants were tested. Contrast is made to ‘Strawberry Festival’ (U.S. Plant Pat. No. 14,739) and ‘Florida Radiance’ (U.S. Plant Pat. No. 20,363), currently the dominant varieties in Hillsborough County, Fla., for reliable description. This new variety is a promising candidate for commercial success because it produces very large, brightly colored, and easy-to-harvest fruit that are moderately firm and highly flavorful during the entire Florida market window.

This strawberry plant (genotype) originated in a strawberry breeding plot in Balm, Fla. The seed parent was ‘FL 05-107’ (U.S. Plant Pat. No. 23,042), a strawberry variety with high early-season yield potential, compact plant habit, and very firm fruit. The pollen parent was FL 02-58, an unreleased breeding selection with the ability to produce large fruit with excellent flavor. The seeds resulting from the controlled hybridization were germinated in a greenhouse, and the resulting seedlings were planted and allowed to produce daughter plants by asexual propagation (i.e. by runners). Four daughter plants from each seedling were transplanted to raised beds, where they fruited. ‘Florida127’ strawberry (as represented by four daughter plants from the original seedling) exhibited high yields and large fruit size, and therefore was selected for further evaluation. ‘Florida127’ was selection number 127 in the 2009-2010 stage 1 trial, and thus was given the breeding trial designation of FL 09-127. ‘Florida127’ has been asexually propagated annually by runners, and further test plantings have established that the vegetative and fruit characteristics of the propagules are identical to the initial daughter plants.

SUMMARY OF THE INVENTION

‘Florida127’, when grown in a subtropical fall and winter climate, is set apart from all other strawberry plants by a combination of the following characteristics: moderately compact growth habit; ease of harvest; and very steady but high yield of fruit that are consistently large in size, bright red, moderately firm and sweetly flavorful.

  - Shape.—Medium conical to cordate in shape.
  - Weight, primary fruit.—35-45 g.
  - Weight, secondary and tertiary fruit.—15-35 g.
  - Fruit flavor.—Sweet, partly due to the consistently high soluble solids content (SSC) of the fruit and moderate acidity (Table 2).
  - Fruit cavity.—Occasional on primary fruit but rare on secondary or tertiary fruit.
  - Achenes.—Slightly sunken, giving the fruit a smooth appearance.
  - External fruit color.—Glossy bright red (a*=38.9).
  - Internal fruit color.—Medium red (a*=24.0).
  - Evenness of color.—Even to slightly uneven during cold and cloudy conditions.
  - Flesh and skin firmness at full ripe stage.—Moderately firm.
  - Rain damage.—‘Florida127’ is less resistant to cracking of the fruit by rain than ‘Strawberry Festival’ and ‘Florida Radiance’.
Total yield: Greater than ‘Strawberry Festival’ during both the 2011-2012 and 2012-2013 seasons (Table 1). Yield was not different from ‘Florida Radiance’ during the 2012-13 season, except in January, when the marketable yield of ‘Florida127’ was significantly greater (Table 1).
Preferred planting period: October 1st to October 15^thin west-central Florida.
- - Nursery performance.—‘Florida127’ is expected to perform well in nursery situations, due to the production of many runners, which results in sturdy, compact daughter plants. This is in contrast to ‘Florida Radiance’, whose daughter plants have weak petioles that are susceptible to breakage during digging and handling.
Disease resistance: ‘Florida127’ is moderately susceptible to Botrytis fruit rot (caused by Botrytis cinerea), similar to ‘Florida Radiance’. ‘Florida127’ is resistant to anthracnose fruit rot (caused by Colletotrichum acutatum).
