Rag-based selection methods for improving aphid resistance in soybeans

摘要

This invention relates to methods of improving resistance to aphids in soybean plants, as well as methods for identifying and/or selecting soybean plants or germplasm that display improved resistance to one or more biotypes of soybean aphid. In certain examples, the method comprises selecting a first and second soybean plant or germplasm, each of which has a different favorable Rag1, Rag2, or Rag3, allele, haplotype, or marker profile, and crossing those first and second soybean plants to produce a progeny plant with improved soybean aphid resistance. This invention further relates to markers, primers, probes, kits, systems, etc., useful for carrying out the methods described herein.
