Abstract

Soybean rust (SBR; caused by Phakopsora pachyrhizi Sydow) is a threat to soybean [Glycine max (L.) Merr.] production worldwide. Although SBR has not caused widespread damage in North America, the crop is still threatened by the disease because most cultivars in production are susceptible. We backcrossed the SBR-resistance genes Rpp1, Rpp1-b, Rpp?(Hyuuga), and Rpp5 into the maturity group (MG) II experimental line LD01-7323 and the MG IV cultivar LD00-3309 to develop Midwest-adapted soybean germplasm with SBR resistance. The backcross lines were tested for SBR resistance in greenhouse tests and for agronomic traits in multilocation field tests. The four MG II soybean germplasm lines LD10- 30052 (Reg. No. GP-383, PI 668384), LD10-14321 (Reg. No. GP- 384, PI 668385), LD10-14284 (Reg. No. GP- 385, PI 668386), and LD09-16057 (Reg. No. GP- 386, PI 668387) and the four MG IV germplasm lines LD10-14205 (Reg. No. GP- 389, PI 668390), LD10-13091 (Reg. No. GP- 387, PI 668388), LD10-14274 (Reg. No. GP- 388, PI 668389), and 08RST5-10 (Reg. No. GP- 390, PI 668391) developed through these efforts were released by the Illinois Agricultural Experiment Station in April 2012.The lines carry SBR resistance genes and are indistinguishable from the recurrent parents for morphological traits and, with only a few exceptions, are not significantly different than their recurrent parents for agronomic traits including seed yield. These lines should be useful to soybean breeders who wish to develop rust-resistant cultivars.
