Abstract
The present disclosure provides pepper plants exhibiting resistance to Phytophthora capsici. Such plants may comprise novel introgressed chromosomal regions associated with disease resistance. 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.
Claims29
A pepper plant of a cultivated pepper variety comprising a recombinant introgression on chromosome 5 that comprises a first allele conferring resistance to Phytophthora capsici, and wherein said first allele lacks a second allele genetically linked thereto that confers a light green immature fruit color phenotype when present.
A method for obtaining a pepper plant of a cultivated variety exhibiting resistance to Phytophthora capsici comprising:
- a) obtaining a pepper plant of a cultivated variety that is heterozygous for a first allele from a donor parent that confers resistance to Phytophthora capsici that is genetically linked to a second allele that confers a light green immature fruit color phenotype;
- b) obtaining progeny of the plant;
- and
- c) selecting at least a first progeny plant in which recombination has occurred such that the progeny comprises said first allele that confers resistance to Phytophthora capsici and lacks said second allele that confers a light green immature fruit color phenotype.
