Abstract

This invention is a new and distinct variety of strawberry plant named ‘Treasure Harvest’. The fruit of ‘Treasure Harvest’ is very large, very firm, flavorful, glossy dark red on the outside, and moderately resistant to Anthracnose fruit rot diseases. The yield is high and tolerant to the heat when grown in west central and west southern Florida. Because of its high yield, firmness, long shell life and excellent fruit quality, ‘Treasure Harvest’ is recommended for fresh market. Due to its dark red color and firm fruit, ‘Treasure Harvest’ is also suitable for processing.

Description

Botanical classification: Fragaria×ananassa Duchesne.
Variety designation: ‘Treasure Harvest’.
SUMMARY OF THE INVENTION
The new and distinct short day strawberry cultivar of the present invention was a part of an ongoing breeding program carried out at Naples, Fla. which has a subtropical climate. The seed resulted from the controlled cross between the strawberry plants ‘Treasure’ (U.S. Plant Pat. No. 12,414) and ‘A4’ (not patented).
The seeds resulting from this cross were germinated in a green house, and seedlings were transplanting to raised beds where they fruited during the season 2001-2002. ‘Treasure Harvest’ was selected for its high yield and superior fruit quality.
For the purpose of further evaluation, ‘Treasure Harvest’ has been asexually propagated by runners at Naples, Fla.; Kentville, Nova Scotia, Canada; and Laurel Springs, N.C.
During seasons 2005-06 & 2006-07 the new cultivar had been put in growers trialed in Plant City, Fla. During the trials this cultivar has shown its characteristics of high yield, large fruit size, good flavor, firm fruit, distinguishable glossy dark red fruit color, and moderate resistance to strawberry Anthracnose fruit rot disease.
The new cultivar of present invention can be distinguished from ‘Treasure’ and other commercial cultivars.
COMPARISON TO CLOSEST CULTIVARS
The commercial cultivar that we believe to be the closest comparison to ‘Treasure Harvest’ in appearance from those known to us is ‘Treasure’ (U.S. Plant Pat. No. 12,414). However, there are several characteristics of ‘Treasure Harvest’ that are different from or not possessed by ‘Treasure’. Those are:
  • Size: The fruit size of ‘Treasure Harvest’ is distinguishable larger when compared with ‘Treasure’.
  • Firmness: The fruit of ‘Treasure Harvest’ is distinguishable firmer when compared with ‘Treasure’.
  • Plant size: The plant size of ‘Treasure Harvest’ is distinguishable larger than that of ‘Treasure’.
  • Anthracnose fruit rot resistance: The plant of ‘Treasure Harvest’ has been screened with three species of strawberry anthracnose fruit rot: Colletotrichum acutatum, C. fragariae and C. gloeosporioides. ‘Treasure Harvest’ was found to be moderately resistant to anthracnose fruit rot, which is one of the major diseases in strawberry growth in the southeastern United States. In comparison, ‘Treasure’ is moderately susceptible to anthracnose fruit rot disease.
  • Bracts: There are no bracts on ‘Treasure Harvest’, but the frequency of bracts on the petioles of ‘Treasure’ is 63.6%.
DESCRIPTION OF THE FIGURES
FIG. 1 shows the general flowering and fruiting characteristics of the plants during mid-season fruit production in Florida. Depicted are: a) a typical mature compound leaf, b) a representative complete flower during the mid-fruiting season, c) a partial fruiting truss including different stages of flowering and fruiting, and d) a typical mature fruit.
FIG. 2 shows plural fruit of the claimed plant reflecting the variation in fruit shape and size within market grade and shows seed and calyx placement relative to the fruit surface, as well as the attractive and uniform coloration of the ripe fruit at harvest stage.
 DESCRIPTION OF THE NEW CULTIVAR
‘Treasure Harvest’ is a new and distinctive short-day type strawberry cultivar which is the result of cross breeding between ‘Treasure’ (U.S. Plant Pat. No. 12,414) and ‘A4’ (not patented). The female parent ‘Treasure’ has the characteristics of large fruit size, high yield, early production, stable production, good fruit quality and good flavor. The male parent ‘A4’ has the characteristics of extra large fruit size, high yield, and vigorous plant. The novel cultivar ‘Treasure Harvest’ resembles the female parent in possessing high yield, stable production, good fruit quality, and good flavor and resembles the male parent in possessing extra large fruit and vigorous plant. ‘Treasure Harvest’ is superior to both parents in possessing firmer fruit, longer shelf life of fruit, and more resistance to Anthracnose fruit rot.
The distinctive characteristics of this new strawberry cultivar, described in detail below were observed upon its discovery and throughout the repeated test periods.
