Merr. | | SOY | | | 2015 | | | | | | | Breeding material | Soybean rust (SBR) is caused by an obligate, biotrophic basidiomycete fungus, Phakopsora pachyrhizi. SBR arrived in the continental USA in 2004, where it has since proven to be detrimental to southeastern soybean production due to its cost of and environmental concerns caused by reliance on fungicides for control. Resistance to SBR has primarily been developed by introgressing single, dominant resistance gene(s) into an elite soybean cultivar background. Here we describe four near-isogenic lines (NIL) of G00-3213 that are referred to as G00-3213Rpp1, G00-3213Rpp2, G00-3213Rpp3, and G00-3213Rpp4. These NILs were developed by backcrossing rust resistance genes Rpp1, Rpp2, Rpp3, or Rpp4 into an elite, maturity VII soybean line G00-3213. These NILs have tawny pubescence, tan pod walls, and white flowers, and had the same general appearance to the elite, recurrent parent G00-3213 in the field in 2014. Additionally, each NIL exhibits a similar level of resistance to the GA12 P. pachyrhizi bulk isolate as the original resistant sources. These NILs will be useful as parents for public and private plant breeders, as well as for extension agents, crop consultants, and plant pathologists to conduct in-field determinations for Rpp gene effectiveness in the southern USA. | 1932252 | PI 676017 |
