The present disclosure provides lettuce plants exhibiting resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.

Downy mildew resistant lettuce plants

The invention provides seed and plants of the lettuce line SVLD1594. The invention thus relates to the plants, seeds, and tissue cultures of lettuce line SVLD1594, and to methods for producing a lettuce plant produced by crossing a plant of lettuce line SVLD1594 with itself or with another lettuce plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of lettuce line SVLD1594, including the gametes of such plants.

Lettuce variety SVLD1594

Lettuce () plants exhibiting resistance tobiotype Nr:1 are provided, together with methods of producing, identifying, or selecting plants or germplasm with abiotype Nr:1 resistance phenotype. Such plants include lettuce plants comprising introgressed genomic regions conferring pest resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed loci, are further provided.

Lettuce plants having resistance tobiotype Nr:1

The invention provides compositions and methods relating to the separation of quantitative Downy Mildew resistance traits from linked but undesirable agronomic traits. The invention further provides plants, plant parts, and seeds comprising such Downy Mildew Resistance traits, which do not comprise alleles specifying undesirable agronomic traits that are genetically linked to the resistance traits.
