Method to identify Asian soybean rust resistance quantitative trait loci in soybean and compositions thereof

摘要

The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding soybean plants containing quantitative trait loci that are associated with resistance to Asian Soybean Rust (ASR), a fungal disease associated with Phakopsora spp. The invention further includes germplasm and the use of germplasm containing quantitative trait loci (QTL) conferring disease resistance for introgression into elite germplasm in a breeding program for resistance to ASR.

1. A method for producing Asian Soybean Rust (ASR) —resistant soybean plants comprising:
a. performing marker assisted selection to identify a soybean plant possessing ASR resistance locus 16, wherein ASR resistance locus 16 is obtainable from PI507009 and identifiable by one or both of the markers NS0113966 and NS0118536, and wherein a resistance allele of each of said markers NS0113966 and NS0118536 comprises SEQ ID NOs: 79 and 80, respectively; and b. generating soybean plants through marker assisted breeding wherein each of said soybean plants comprise ASR resistance locus 16 [and at least one of ASR resistance loci 1-15] and each of said soybean plants exhibits at least partial resistance to ASR.
