Abstract: According to the invention, there is provided a novel romaine lettuce cultivar, designated Prima Forest. ‘Prima Forest’ is described as a vigorous romaine cultivar recommended for the main lettuce growing regions of California and Arizona. It has light plant weight, small core diameter, short plant height and also has resistance to lettuce downy mildew. This invention thus relates to the seeds of lettuce cultivar Prima Forest, to the plants of lettuce cultivar Prima Forest, to plant parts of lettuce cultivar Prima Forest, to methods for producing a lettuce cultivar by crossing the lettuce cultivar Prima Forest 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.

Abstract: According to the invention, there is provided a novel romaine lettuce cultivar, designated Rocky Row. ‘Rocky Row’ is described as a vigorous romaine cultivar recommended for the main lettuce growing regions of California for the spring sowing. It has lighter plant weight, long core length, tall plant height, long leaf length, with resistance to Tomato bushy Stunt virus, and lettuce downy mildew. This invention thus relates to the seeds of lettuce cultivar Rocky Row, to the plants of lettuce cultivar Rocky Row, to plant parts of lettuce cultivar Rocky Row, to methods for producing a lettuce cultivar by crossing the lettuce cultivar Rocky Row 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.

Abstract: According to the invention, there is provided a novel romaine lettuce cultivar, designated Solid King. ‘Solid King’ is described as a vigorous romaine cultivar with large frame size and heavier weight, short core length, savoyed and glossy leaf color, corky root rot resistance, no fringe burn on mature leaves and also yellower heart leaf color with a solid mid rib. This invention thus relates to the seeds of lettuce cultivar Solid King, to the plants of lettuce cultivar Solid King, to plant parts of lettuce cultivar Solid King, to methods for producing a lettuce cultivar by crossing the lettuce cultivar Solid King 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.

Abstract: A novel romaine lettuce cultivar, designated Heartbreaker, is disclosed. The invention relates to the seeds of lettuce cultivar Heartbreaker, to the plants of lettuce cultivar Heartbreaker and to methods for producing a lettuce plant by crossing the cultivar Heartbreaker with itself or another lettuce cultivar. 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 cultivars derived from the cultivar Heartbreaker.

Abstract: A novel romaine lettuce cultivar, designated Sun Valley, is disclosed. The invention relates to the seeds of lettuce cultivar Sun Valley, to the plants of lettuce cultivar Sun Valley and to methods for producing a lettuce plant by crossing the cultivar Sun Valley with itself or another lettuce cultivar. 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 cultivars derived from the cultivar Sun Valley.

Abstract: Disclosed herein is the present invention which relates to a new distinct romaine (Cos) Lactuca sativa cultivar designated ‘Thermo Cos’, which exhibits resistance to lettuce drop and tipbum, a leaf color of Value 4 Chroma 4 Hue 7.5 GY according to the Munsell Color Chart for Plant Tissues.

Abstract: The present invention relates to a new Romaine (Cos) Lactuca sativa cultivar designated Green Forest, which exhibits resistance to lettuce drop and tipburn, a leaf color of Value 3 Chroma 4 Hue 7.5 GY according to the Munsel Color Chart for Plant Tissues and weighs about 4.7% more than the comparable varieties of Romaine Lettuce.
