Whitaker; Cheryl Dalid; Luis Osorio - Web page: https://patentgrep.com/patent/US20260083084A1 ## CPC - A01H 6/7409: {Fragaria, i.e. strawberries} - A01H 5/08: Fruits - A01H: NEW PLANTS OR {NON-TRANSGENIC} PROCESSES FOR OBTAINING THEM; PLANT REPRODUCTION BY TISSUE CULTURE TECHNIQUES ## Abstract The invention provides plants of the strawberry variety designated ‘FL 19.66-220’. The invention thus relates to the plants, cells, plant parts, and tissue cultures of variety ‘FL 19.66-220’, and to methods for producing a strawberry plant produced by crossing a strawberry plant of strawberry variety ‘FL 19.66-220’ with another strawberry plant, such as a plant of another variety. The invention further relates to strawberry seeds and plants produced by crossing plants of variety ‘FL 19.66-220’ with plants of another variety. ## Claims ### Claim 1 A strawberry plant of variety ‘FL 19.66-220’, a representative sample of plant tissue of said variety having been deposited under NCMA Accession No. ______. ### Claim 2 (depends on 1) A plant part of the plant of claim 1, wherein said plant part comprises at least one cell of said plant. ### Claim 3 (depends on 2) The plant part of claim 2, defined as a flower, pollen, a leaf, an ovule, an embryo, a cutting, a stem, a seed, or a fruit. ### Claim 4 (depends on 1) A strawberry plant, or a part thereof, having all of the physiological and morphological characteristics of the plant of claim 1. ### Claim 5 (depends on 1) A tissue culture of regenerable cells of the plant of claim 1. ### Claim 6 (depends on 5) The tissue culture according to claim 5, comprising cells or protoplasts from a plant part selected from the group consisting of embryos, meristems, pollen, leaves, anthers, roots, root tips, pistils, and flowers. ### Claim 7 (depends on 5) A strawberry plant regenerated from the tissue culture of claim 5, wherein the regenerated plant comprises all of the physiological and morphological characteristics of strawberry variety ‘FL 19.66-220’, a sample of plant tissue of said variety having been deposited under NCMA Accession No. ______. ### Claim 8 (depends on 1) A method for producing a seed of a strawberry plant derived from strawberry variety ‘FL 19.66-220’, the method comprising the steps of: (a) crossing the plant of claim 1 with itself or a second strawberry plant; and (b) allowing seed of a strawberry variety ‘FL 19.66-220’-derived strawberry plant to form. ### Claim 9 (depends on 8) The method of claim 8, the method further comprising the steps of: (c) crossing a plant grown from said ‘FL 19.66-220’-derived strawberry seed with itself or a second strawberry plant to yield additional ‘FL 19.66-220’-derived strawberry seed; (d) growing said additional ‘FL 19.66-220’-derived strawberry seed of step (c) to yield additional ‘FL 19.66-220’-derived strawberry plants; and (e) repeating the crossing and growing steps of (c) and (d) to generate further ‘FL 19.66-220’-derived strawberry plants. ### Claim 10 (depends on 1) A method of vegetatively propagating the plant of claim 1, the method comprising the steps of: (a) collecting tissue capable of being propagated from the plant of claim 1; and (b) propagating a strawberry plant from the tissue. ### Claim 11 (depends on 1) A method of introducing a trait into a strawberry plant, the method comprising: (a) utilizing as a recurrent parent the plant of claim 1 by crossing the plant with a donor strawberry plant that comprises the trait to produce F1 progeny; (b) selecting an F1 progeny that comprises the trait; (c) backcrossing the selected F1 progeny with a plant of the same strawberry variety used as a recurrent parent in step (a) to produce backcross progeny; (d) selecting a backcross progeny that comprises the trait; and (e) repeating steps (c) and (d) at least one more time to produce a selected second or higher backcross. ### Claim 12 (depends on 11) The method of claim 11, wherein the backcross progeny comprises the trait and otherwise comprises all of the physiological and morphological characteristics of the recurrent strawberry variety used in step (a). ### Claim 13 (depends on 1) A method of producing a strawberry plant comprising an added trait, the method comprising introducing by genetic transformation a transgene conferring the trait into a plant of claim 1. ### Claim 14 (depends on 13) A strawberry plant produced by the method of claim 13. ### Claim 15 A strawberry plant of strawberry variety ‘FL 19.66-220’, a sample of plant tissue of said variety ‘FL 19.66-220’ having been deposited under NCMA Accession No. ______, further comprising a transgene. ### Claim 16 (depends on 15) The plant of claim 15, wherein the transgene confers a trait selected from the group consisting of improved fruit size, improved fruit shape, improved firmness, increased yield, enhanced fruit flavor, and increased shelf-life. ### Claim 17 A strawberry plant of strawberry variety ‘FL 19.66-220’, a sample of plant tissue of said variety ‘FL 19.66-220’ having been deposited under NCMA Accession No. ______, further comprising a single locus conversion. ### Claim 18 (depends on 17) The plant of claim 17, wherein the single locus conversion confers a trait selected from the group consisting of improved fruit size, improved fruit shape, improved firmness, increased yield, enhanced fruit flavor, and increased shelf-life. ### Claim 19 (depends on 1) A method of producing a strawberry fruit comprising: (a) obtaining the plant of claim 1, wherein the plant has been cultivated to maturity, and (b) collecting at least one strawberry fruit from the plant.
