Abstract
Pepper plants exhibiting resistance to root knot nematode species are provided, together with methods of producing, identifying, or selecting plants or germplasm with a root knot nematode resistance phenotype. Such plants include pepper plants comprising introgressed genomic regions conferring pest resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed pest resistance alleles, are further provided.
Claims21
A method for producing a Capsicum annuum plant exhibiting resistance to root knot nematodes, comprising:
- a) crossing a Capsicum annuum plant comprising an introgressed allele on chromosome 9 that confers increased resistance to root knot nematodes compared to a plant not comprising said allele, wherein said plant is a non-jalapeno variety, and wherein said introgressed allele is located between Marker_6 (SEQ ID NO:
- 1) and Marker_10 (SEQ ID NO:
- 21) on chromosome 9 with itself or with a second Capsicum annuum plant of a different genotype to produce one or more progeny plants;
- and
- b) selecting a progeny plant comprising said introgressed allele.
A method of producing a Capsicum annuum plant exhibiting resistance to root knot nematodes, comprising introgressing into a plant a root knot nematode resistance allele, wherein said resistance allele is defined as located in a genomic region between 250,338,645 bp and 250,504,749 bp on chromosome 9 on the physical map of CM334 v1.55.
A method of selecting a Capsicum annuum plant exhibiting resistance to root knot nematodes, comprising:
- a) crossing a Capsicum annuum plant comprising an introgressed allele on chromosome 9 that confers increased resistance to root knot nematodes compared to a plant not comprising said allele, wherein said plant is a non-jalapeno variety, and wherein said introgressed allele is located between Marker_6 (SEQ ID NO:
- 1) and Marker_10 (SEQ ID NO:
- 21) on chromosome 9 with itself or with a second Capsicum annuum plant of a different genotype to produce one or more progeny plants;
- and
- b) selecting a progeny plant comprising said introgressed allele.
