Abstract
The present invention is in the field of plant breeding and aphid resistance. More specifically, the invention includes a method for breeding soybean plants containing quantitative trait loci that are associated with resistance to aphids, Aphis glycines. The invention further includes method for monitoring the introgression quantitative trait loci (QTL) conferring aphid resistance into elite germplasm in a breeding program.
Claims10
A method of producing an aphid resistant population of soybean plants comprising:
- (A) Genotyping at least one soybean plant from a first population of soybean plants with respect to a soybean genomic nucleic acid marker selected from the group consisting of SEQ ID NO:
- 117, 118, 119, and 120, wherein said nucleic acid marker is indicative of an allele conferring aphid resistance in a soybean plant,
- (B) Selecting at least one soybean plant from the first population based upon said genotyping for the presence of said allele conferring aphid resistance in a soybean plant, and
- (C) Crossing the selected soybean plant having said allele conferring aphid resistance with an aphid susceptible soybean plant to produce a second population of soybean plants having aphid resistance,
- thereby creating an aphid resistant population of soybean plants comprising a soybean genomic nucleic acid marker selected from the group consisting of SEQ ID NO:
- 117, 118, 119, and 120, wherein said nucleic acid marker is indicative of an allele conferring aphid resistance in a soybean plant.
A method of introgressing an allele into a soybean plant comprising:
- (A) crossing at least one aphid resistant soybean plant with at least one aphid sensitive soybean plant in order to form a segregating population,
- (B) screening said segregating population with one or more nucleic acid markers to determine if one or more soybean plants from said segregating population contains an aphid resistant locus comprising SEQ ID NO:
- 117, 118, 119, or 120.
