Estimating the term…
Tomato plants exhibiting resistance to Stemphylium are provided, together with methods of producing, identifying, or selecting plants or germplasm with a Stemphylium resistance phenotype and lacking an undesirable small fruit size trait. Such plants include tomato plants comprising introgressed genomic regions conferring disease resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.
A Solanum lycopersicum plant comprising a recombinant chromosomal segment on chromosome 11, wherein said chromosomal segment comprises a Stemphylium resistance allele from Solanum pimpinellifolium conferring increased resistance to Stemphylium to said plant compared to a plant not comprising said allele, and wherein the chromosomal segment lacks a deleterious allele genetically linked to said Stemphylium resistance allele that confers small fruit size when present.
A recombinant DNA segment comprising a Stemphylium resistance allele from Solanum pimpinellifolium that confers to a Solanum lycopersicum plant increased resistance to Stemphylium and lacking a deleterious allele genetically linked thereto that confers small fruit size.
A method of producing a tomato plant exhibiting resistance to Stemphylium, comprising introgressing into a plant a Stemphylium resistance allele from Solanum pimpinellifolium within a recombinant chromosomal segment flanked in the genome of said plant by:
