 DETAILED DESCRIPTION Definitions

In order to more clearly understand the invention, the following definitions are provided:

Core Length: Core length is the length of the internal lettuce stem. Core length is measured from the base of the cut head to the tip of the core.

Core Diameter: Core diameter is the diameter of the lettuce stem at the base of the cut head.

Heart Length: Heart length is the length of the vertically sliced lettuce plant as measured from the base of the cut stem to the top leaf margin of the longest outermost leaf that encloses the green leaf heart.

Plant Diameter: The plant diameter is a measurement across the top of the lettuce plant at its widest point. The measurement of frame diameter is taken from the outer most leaf tip horizontally to the outer most leaf tip.

Head Diameter: Head diameter is the diameter of the vertically sliced lettuce plant head at its widest horizontal point, perpendicular to the stem.

Head Length: Head length is the diameter of the vertically sliced lettuce plant head as measured from the base of the cut stem to the cap leaf.

Head Weight: Head weight is the weight of the marketable lettuce plant, cut and trimmed to market specifications.

Lettuce Mosaic Virus: A disease that can cause a stunted, deformed, or mottled pattern in young lettuce and yellow, twisted, and deformed leaves in older lettuce.

Maturity Date: Maturity refers to the stage when the plants are of full size or optimum weight, in marketable form or shape to be of commercial or economic value.

Nasonovia ribisnigri: A lettuce aphid that colonizes the innermost leaves of the lettuce plant, contaminating areas that cannot be treated easily with insecticides.

Tip burn: Means a browning of the edges or tips of lettuce leaves that is a physiological response to a lack of calcium.

Tomato Bushy Stunt: Lettuce dieback was first observed in California in the mid-1980s, and reports of the disease have increased over the last 10 years. Complete crop losses have occurred in fields of Green Leaf lettuce, and no commercial Green Leaf cultivar has been shown to be resistant to the disease. In the U.S., Green Leaf is a rapidly growing market segment, having increased 68% over the last five years (USDA, 2002). The disease has occurred in commercial fields of some leaf lettuce cultivars; however, symptoms have never been observed on any modern crisphead (iceberg) cultivars. Lettuce dieback is caused by several related tombusviruses including tomato bushy stunt virus (TBSV) and lettuce necrotic stunt virus (LNSV) (Liu et al., 1999; Obermeier et al., 2001). These are soil-borne, highly stable, and mechanically transmitted, and have no known vector. The conditions affecting symptom development remain poorly understood. The disease is frequently observed in low-lying areas of fields with a prior history of flooding, suggesting that the virus may be carried in river water and/or that disease symptoms may be associated with increased root stresses such as those presented by excess moisture. No effective cultural or chemical control methods have yet been identified.

Resistance to Tomato Busy Stunt refers to a level of resistance in a lettuce variety as measured by visual symptoms. Resistance is deemed present when symptoms are not present in at least 95% of a lettuce variety when exposed to tomato bushy stunt virus (TBSV).

Taking into account these definitions, the present invention is directed to seeds of the lettuce varieties ‘Wheelhouse’, ‘Trailblazer’, ‘Haymaker’, 14RDSJV055-1 ‘, 14RDSJV055-3’, ‘14RDSJV055-7’, ‘PS 1102B’, ‘Hercules’, and ‘Canyon’, plants produced by growing ‘Wheelhouse’, ‘Trailblazer’, ‘Haymaker’, ‘14RDSJV055-1’, ‘14RDSJV055-3’, ‘14RDSJV055-7’, ‘PS 1102B’, ‘Hercules’, and/or ‘Canyon’ lettuce seeds, heads isolated or harvested from the plants, one or more plants selected from a collection of ‘Wheelhouse’, ‘Trailblazer’, ‘Haymaker’, ‘14RDSJV055-1’, ‘14RDSJV055-3’, ‘14RDSJV055-7’, ‘PS 1102B’, ‘Hercules’, and/or ‘Canyon’ plants and seeds derived or produced therefrom; plants produced by crossing a lettuce plant with a ‘Wheelhouse’, ‘Trailblazer’, ‘Haymaker’, ‘14RDSJV055-1’, ‘14RDSJV055-3’, ‘14RDSJV055-7’, ‘PS 1102B’, ‘Hercules’, and/or ‘Canyon’ lettuce plant and seeds derived or produced therefrom.

Further Embodiments

Breeding

In lettuce breeding, lines are selected for their appropriate characteristics. For example, one line may be selected for bolt tolerance in the fall growing conditions of the desert production locations of California and Arizona. Another line may be selected for the size, color, and texture of the lettuce head. Crosses are made, for example, to produce a dark green, sure heading iceberg lettuce with improved texture, and size for fall plantings in Yuma, Ariz. and Huron, Calif.

To optimize crossing, it is important to note that lettuce is an obligate self-pollinating species. This means that the pollen is shed before stigma emergence, assuring 100% self-fertilization. Since each lettuce flower is an aggregate of about 10-20 individual florets (typical of the Compositae family), manual removal of the anther tubes containing the pollen is performed by procedures well known in the art of lettuce breeding.

The manual removal of anther tubes, though an effective means to ensure the removal of all self pollinating possibilities, is very tedious and time consuming when a large number of crosses are to be made. The breeders have therefore adapted a well documented and modified method of making crosses more efficiently using these methods. This particular cross was made by first misting the designated male flowers to wash the pollen off prior to fertilization. This process of misting is a proven and effective means of pollen removal that assures crossing or hybridization. About 60-90 minutes past sunrise, flowers to be used for crossings are selected. The basis for selection are open flowers, with the stigma emerged and the pollen visibly attached to the single stigma (about 10-20 stigma). Using 3-4 pumps of water from a regular spray bottle, the pollen is washed off with enough pressure to dislodge the pollen grains, but not enough to damage the style. Excess water is dried off with clean paper towels. About 30 minutes later, the styles should spring back up and the two lobes of the stigma are visibly open in a “V” shape. Pollen from another variety or donor parent is then introduced by gently rubbing the stigma and style of the donor parent to the maternal parent. Tags with the pertinent information on date and pedigree are then secured to the flowers in order to keep track.

About 2-3 weeks after pollination, seeds are harvested when the involucre have matured. The seeds are eventually sown and in the presence of markers such as leaf color or leaf margins, the selfed or maternal seedlings or plants are identified. Generally, there are no visible markers and breeders must wait until the F2 generations when expected segregation patterns for the genetic character of interest can be followed. This latter situation mandates a lengthy wait to determine if hybrids are produced. Two relevant references teaching methods for out crossing lettuce are: (1) Ryder, E. J. and A. S. Johnson. 1974. Mist depollination of lettuce flowers. Hortscience 9:584; and (2) Nagata, R. T. 1992. Clip and Wash Method of Emasculation for Lettuce. Hortscience 27(8):907-908 both of which are hereby incorporated by reference in their entirety for the purpose of providing details on the techniques well known in the art.

Selection

In addition to crossing, selection may be used to identify and isolate new lettuce lines. In lettuce selection, lettuce seeds are planted, the plants are grown and single plant selections are made of plants with desired characteristics. Such characteristics may include improved head and frame size, deeper or darker green leaf color, etc. Seed from the single plant selections are harvested, separated from seeds of the other plants in the field and re-planted. The plants from the selected seed are monitored to determine if they exhibit the desired characteristics of the originally selected line. Selection work is continued over multiple generations to increase the uniformity of the new line.
