Abstract
The invention relates to spinach plants comprising a multileaf trait. The invention provides methods and compositions for generating such spinach plants with multileaf trait. The invention also provides seed and plants of spinach with multileaf trait. The invention thus relates to the plants, seeds and tissue cultures of spinach with multileaf trait, and to methods for producing a spinach plant produced by crossing such plants with themselves or with another spinach plant, such as a plant of another genotype. The invention further relates to parts of such plants, including the leaf and gametes of such plants.
Claims42
A spinach plant which carries the multileaf trait of a multileaf trait spinach, wherein said spinach plant comprises the genetic source for the multileaf trait from spinach line SSB66-1129 F, a sample of the seed of which has been deposited under ATCC Accession No. PTA-12019, wherein the plant comprises at least 1.25 times as many leaves as a spinach plant not having the multileaf trait, when comparison is made between plants in the same developmental stage.
3-5. (canceled)
A seed of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019.
A tissue culture of regenerable cells of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019.
A method for producing a seed of a multileaf trait-derived spinach plant comprising the steps of:
- (a) crossing a multileaf trait spinach plant, representative seed of which has been deposited under ATCC Accession No. PTA-12019, with a second spinach plant;
- (b) whereby seed of multileaf trait-derived spinach planter forms.
The method of claim 42, further comprising the steps of:
- (c) crossing a plant grown from said multileaf trait-derived spinach seed with itself or a second spinach plant to yield additional multileaf trait-derived spinach seed;
- (d) growing said additional multileaf trait-derived spinach seed of step (c) to yield additional multileaf trait-derived spinach plants;
- and (e) repeating the crossing and growing steps of (c) and (d) to generate further multileaf trait-derived spinach plants.
A method of vegetatively propagating a plant of multileaf trait spinach comprising the steps of:
- (a) collecting tissue capable of being propagated from a plant of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA 12019;
- (b) cultivating said tissue to obtain proliferated shoots;
- and (c) rooting said proliferated shoots to obtain rooted plantlets.
A method of introducing a desired trait into multileaf trait spinach comprising:
- (a) crossing a plant of multileaf spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019, with a second spinach plant that comprises a desired trait to produce F1 progeny;
- (b) selecting an F1 progeny that comprises the desired trait;
- (c) crossing the selected F1 progeny with a multileaf spinach plant, representative seed of which has been deposited under ATCC Accession No. PTA-12019, to produce backcross progeny;
- (d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristics of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019;
- and (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny that comprise the desired trait and all of the physiological and morphological characteristics of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019, when grown in the same environmental conditions.
A multileaf trait spinach plant produced by the method of claim 46.
A method of producing a plant of multileaf trait spinach, representative seed of which has been deposited under ATCC Accession No. PTA-12019, comprising an added desired trait, the method comprising introducing a transgene conferring the desired trait into a plant of multileaf trait spinach.
