Abstract
According to the invention, there is provided a novel romaine lettuce cultivar, designated Valencia. Valencia is described as a vigorous romaine cultivar and recommended for the main lettuce growing regions of California and Arizona. This invention thus relates to the seeds of lettuce cultivar Valencia, to the plants of lettuce cultivar Valencia, to plant parts of lettuce cultivar Valencia, to methods for producing a lettuce cultivar by crossing the lettuce cultivar Valencia with another lettuce cultivar, and to methods for producing a lettuce cultivar containing in its genetic material one or more backcross conversion traits or transgenes and to the backcross conversion lettuce plants and plant parts produced by those methods.
Claims22
A seed of lettuce variety Valencia, wherein a representative sample of seed of said lettuce variety having been deposited under ATCC Accession No. PTA-______.
A lettuce plant having all of the characteristics of lettuce variety Valencia listed in Table 1 when grown in the same environmental conditions, or a part or a plant cell thereof.
(canceled)
A method of introducing a desired trait into lettuce polynucleotide Valencia, the method comprising:
- (a) crossing a plant of lettuce variety Valencia grown from seed of lettuce variety Valencia, wherein a representative sample of seed has been deposited under ATCC Accession No. PTA-______, with another lettuce plant that comprises a desired trait to produce at least one F1 progeny plant, wherein the desired trait is selected from the group consisting of insect resistance, herbicide resistance, disease resistance, water stress tolerance, heat tolerance, improved shelf life, delayed shelf life, and improved nutritional quality;
- (b) selecting one or more progeny plants that have the desired trait to produce at least one selected progeny plant;
- (c) crossing at least one selected progeny plant with at least one plant of the lettuce variety Valencia to produce at least one backcross progeny plant;
- (d) selecting for at least one backcross progeny plant that has the desired trait and the physiological and morphological characteristics of lettuce variety Valencia listed in Table 1 when grown in the same environmental conditions to produce at least one selected backcross progeny plant;
- and
- (e) repeating steps (c) and (d) three or more times in succession to produce at least one selected fourth or higher backcross progeny plant that comprises the desired trait and the physiological and morphological characteristics of lettuce variety Valencia listed in Table 1 when grown in the same environmental conditions.
A method of vegetatively propagating a plant of lettuce variety Valencia comprising:
- (a) collecting tissue capable of being propagated from a plant of lettuce variety Valencia, a sample of seed of the variety having been deposited under ATCC Accession No. PTA-______;
- (b) cultivating the tissue to obtain proliferated shoots and rooting the proliferated shoots to obtain rooted plantlets;
- and
- (c) optionally growing plants from the rooted plantlets.
