Genetic determinants of lettuce resistance to drop caused by Sclerotinia minor identified through genome-wide association mapping frequently co-locate with loci regulating anthocyanin content.

GWAS identified 19 QTLs for resistance to Sclerotinia minor, 11 of them co-locating with red leaf color. Lower disease incidence was observed in red and dark red accessions. Lettuce (Lactuca sativa L.

Development and Characterization of 20 Genomic SSR Markers for Ornamental Cultivars of .

(Caprifoliaceae) is a genus of ornamental plants popular for its phenotypic variation and hardiness, that includes species hybridized to produce the commercially available cultivars. Despite its popularity, limited genetic resources exist for the genus. Twenty genomic simple sequence repeat (gSSR) markers distributed across the genome were developed using low coverage whole-genome sequencing data of Spilled Wine.

Genome-wide association mapping reveals genomic regions frequently associated with lettuce field resistance to downy mildew.

GWAS identified 63 QTLs for resistance to downy mildew. Though QTLs were distributed across all chromosomes, the genomic regions frequently associated with resistance were located on chromosomes 4 and 5. Lettuce downy mildew is one of the most economically important diseases of cultivated lettuce worldwide.

Identification of Quantitative Trait Loci Associated with Bacterial Leaf Spot Resistance in Baby Leaf Lettuce.

Spring mix is a popular packaged salad that contains lettuce ( L.) as one of its main ingredients. Plants for baby leaf lettuce (BLL) production are grown at very high densities, which enhances the occurrence of bacterial leaf spot (BLS) caused by pv.

Genome-wide association mapping reveals loci for shelf life and developmental rate of lettuce.

Two major QTL, one for shelf life that corresponds to qSL4 and one, qDEV7, for developmental rate, were identified. Associated markers will be useful in breeding for improved fresh-cut lettuce. Fresh-cut lettuce in packaged salad can have short shelf life, and visible deterioration may start within a week after processing.
