Narrative
One objective of the Iowa State University soybean breeding program is to develop germplasm lines with new genetic resources for pathogen resistance. Germplasm line AR20SBR (Experimental line AR15-359045) of MG IV (Reg. No. ________, PI __________) derived from a cross of an Asian soybean rust resistant accession PI 567104B and IAR2001 BSR. IAR2001 BSR is a high-yielding cultivar resistant to BSR that has two BSR resistance genes (Rbs1 and Rbs3) inherited from PI 84946-2. AR20SBR germplasm line is a F 7:8 bulk of 60 agronomically uniform plants from the mentioned cross. Phenotyping in field and growth chamber assays showed that AR20SBR was highly resistant to SBR. Growth chamber assays confirmed that AR20SBR was also highly resistant to BSR. The molecular marker analysis indicated confirmed that AR20SBR inherited the new SBR resistance gene identified from PI 567104B, and it also inherited the BSR resistance genes (Rbs1 and Rbs3) from IAR2001 BSR. AR20SBR yielded 80 % compared to the respective high-yielding maturity checks in the field trials. AR20SBR may be used in breeding programs as donor of the new SBR resistance gene and also BSR resistance genes, for the southern US regions in which SBR and BSR resistance is of economic importance. The line could also serve as genetic stock in soybean research.

Pedigree
Description:
AR20SBR is an F7:8 germplasm line identified from a group of 253 RIL population (designated as AX20871) from the cross of IAR2001 BSR × PI 567104B made in Puerto Rico in 2006. IAR2001 BSR (Cianzio et al., 2007; ISURF Docket # 03542) belongs to MG II. IAR2001 BSR, is a high-yielding cultivar possessing the Rbs1 and Rbs3 genes that confer resistance to the BSR pathogen. PI 567104B is a MG IX soybean accession from Indonesia identified as highly resistant line to Asian soybean rust (SBR).
