Abstract
A novel romaine lettuce cultivar, designated 163502, is disclosed. The invention relates to the seeds of lettuce cultivar 163502, to the plants of lettuce line 163502 and to methods for producing a lettuce plant by crossing the cultivar 163502 with itself or another lettuce (Lactuca sp.) line. The invention further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other lettuce lines derived from the cultivar 163502.
Claims24
A seed of a lettuce variety designated 163502, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-6794.
A lettuce plant, or a part thereof, having all the physiological and morphological characteristics of lettuce variety 163502, wherein a representative sample of seed of said variety was deposited under ATCC Accession No. PTA-6794.
A method of introducing a desired trait into lettuce variety 163502 wherein the method comprises:
- (a) crossing lettuce variety 163502 plants grown from lettuce variety 163502 seed, representative seed of which has been deposited under ATCC Accession No. PTA-6794, with plants of another lettuce variety that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, Insect resistance and disease resistance;
- (b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
- (c) crossing the selected progeny plants with the lettuce variety 163502 plants to produce backcross progeny plants;
- (d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of lettuce variety 163502 listed in the VARIETY DESCRIPTION INFORMATION to produce selected backcross progeny plants;
- and
- (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of lettuce variety 163502 listed in the VARIETY DESCRIPTION INFORMATION as determined at the 5% significance level when grown in the same environmental conditions.
