Latin name: Botanical classification: Fragaria x ananassa.
Varietal denomination: The varietal denomination of the claimed variety of strawberry plant is ‘DrisStrawSeventyThree’.
Cultivated strawberry is a hybrid species of the genus Fragaria that is grown worldwide for its fruit. Modern strawberry was first bred in Brittany, France, in the 18th century by crossing Fragaria virginiana with Fragaria chiloensis. Strawberry fruit is an aggregate accessory fruit, with the fleshy part of the fruit being derived from the receptacle that holds the ovaries.
Strawberry varieties vary widely in color, size, shape, flavor, season of ripening, degree of fertility, and susceptibility to disease. Certain varieties vary in foliage, and some vary in the relative development of their reproductive organs. Typically, strawberry flowers appear hermaphroditic in structure, but function as either male or female. Generally, commercial production of strawberry plants involves propagation from runners and distribution as either plugs or bare root plants. Cultivation is either perennial or annual plasticulture. During the off season, strawberries can also be produced in greenhouses.
Strawberry fruit is widely appreciated for its characteristic bright red color, aroma, juicy texture, and sweetness. Strawberry fruit is a popular fruit that is generally consumed either fresh or in prepared foods, such as preserves and baked goods.
Strawberry is an important and valuable fruit crop. Accordingly, there is a need for new varieties of strawberry plants. In particular, there is a need for improved varieties of strawberry plant that are stable, high yielding, and agronomically sound.
In order to meet these needs, the present invention is directed to an improved variety of strawberry plant. In particular, the invention relates to a new and distinct variety of strawberry plant (Fragaria x ananassa), which has been denominated as ‘DrisStrawSeventyThree’.
Strawberry plant variety ‘DrisStrawSeventyThree’ was discovered in Huelva, Spain in 2014, and originated from a cross between the female parent ‘DrisStrawThirtyFour’ (U.S. Plant Pat. No. 24,395) and the male parent ‘VES 030-092’ (unpatented). ‘DrisStrawSeventyThree’ was first asexually propagated via stolons in Valladolid, Spain in 2014.
‘DrisStrawSeventyThree’ was subsequently asexually propagated via stolons and underwent further testing in Huelva, Spain for three years (from 2015 to 2018). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons.
‘DrisStrawSeventyThree’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in Huelva, Spain:
1. Horizontal attitude of hairs on pedicels;
2. Absent or very narrow width of band without achenes on fruit
3. Achenes level with surface of fruit; and
4. Calyx attachment inserted in fruit.
‘DrisStrawSeventyThree’ was selected for its conical fruit shape, juicy fruit flesh with good post-harvest qualities, large fruit size, healthy and strong plants, and productivity.
This new strawberry plant is illustrated by the accompanying photographs. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are five months from planting.
The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawSeventyThree’. The data which define these characteristics is based on observations taken in Huelva, Spain from 2015 to 2018. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic, and cultural conditions. ‘DrisStrawSeventyThree’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawSeventyThree’ was taken from plants that were five months from planting. The indicated values represent averages calculated from measurements of several plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.
‘DrisStrawSeventyThree’ differs from the female parent ‘DrisStrawThirtyFour’ (U.S. Plant Pat. No. 24,395) in that ‘DrisStrawSeventyThree’ has better fruit post-harvest quality and a later maturity as compared to ‘DrisStrawThirtyFour’.
‘DrisStrawSeventyThree’ differs from the male parent ‘VES 030-092’ (unpatented) in that ‘DrisStrawSeventyThree’ has better fruit post-harvest quality and an earlier maturity as compared to ‘VES 030-092’. Further, fruit of ‘DrisStrawSeventyThree’ are much larger in size than fruit of ‘VES 030-092’.
‘DrisStrawSeventyThree’ differs from the commercial variety ‘DrisStrawTwentySeven’ (U.S. Plant Pat. No. 23,400) in that fruit of ‘DrisStrawSeventyThree’ have absent or very narrow width of band without achenes, whereas fruit of ‘DrisStrawTwentySeven’ have very broad width of band without achenes. Further, fruit of ‘DrisStrawSeventyThree’ have achenes level with surface, whereas fruit of ‘DrisStrawTwentySeven’ have achenes below surface. Moreover, fruit of ‘DrisStrawSeventyThree’ have calyx attachment inserted in fruit, whereas fruit of ‘DrisStrawTwentySeven’ have calyx attachment raised from fruit. In addition, fruit of ‘DrisStrawSeventyThree’ have a strong adherence of calyx, whereas fruit of ‘DrisStrawTwentySeven’ have a weak adherence of calyx.
‘DrisStrawSeventyThree’ differs from the commercial variety ‘DrisStrawSixteen’ (U.S. Plant Pat. No. 22,247) in that petioles of ‘DrisStrawSeventyThree’ have a horizontal attitude of hairs, whereas petioles of ‘DrisStrawSixteen’ have an upwards attitude of hairs. Further, pedicels of ‘DrisStrawSeventyThree’ have a horizontal attitude of hairs, whereas pedicels of ‘DrisStrawSixteen’ have an upwards attitude of hairs. Moreover, fruit of ‘DrisStrawSeventyThree’ have calyx attachment inserted in fruit, whereas fruit of ‘DrisStrawSixteen’ have calyx attachment level with fruit. In addition, fruit of ‘DrisStrawSeventyThree’ have an upwards attitude of sepals, whereas fruit of ‘DrisStrawSixteen’ have an outwards attitude of sepals.
