Genetic Loci Associated with Fusarium Solani Tolerance in Soybean

摘要

The invention relates to methods and compositions for identifying soybean plants that are tolerant, have improved tolerance or are susceptible to Fusarium solani infection (the causative agent of sudden death syndrome or SDS). The methods use molecular genetic markers to identify, select and/or construct disease-tolerant plants or identify and counter-select disease-susceptible plants. Soybean plants that display tolerance or improved tolerance to Fusarium solani infection that are generated by the methods of the invention are also a feature of the invention.

主权项

1. A method of identifying a first soybean plant or germplasm that displays tolerance or improved tolerance to Fusarium solani infection, the method comprising detecting in the first soybean plant or germplasm at least one allele of one or more marker locus that is associated with the tolerance or improved tolerance, wherein the one or more marker locus is selected from the group consisting of:
(a) SATT166, SATT448, SATT678, SAT 099, S60375-TB, SATT006, SATT229, SATT373, SAT—340, Sct—010, SATT076, SAT—113, SATT678, SATT527, SATT561, and A132—2; and (b) a marker locus closely linked to the marker locus of (a).
