Registration of LD00‐2817P Soybean Germplasm Line with Resistance to Soybean Cyst Nematode from PI 437654

Abstract

The soybean [Glycine max (L.) Merr.] germplasm line LD00‐2817P (Reg. No. GP‐367, PI 658519) was developed at the University of Illinois Agricultural Experiment Station at Urbana, IL. The objective of the breeding effort that resulted in this release was the combining of high yield with soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) resistance from underutilized resistance sources. LD00‐2817P was selected from the cross ‘Ina’ × ‘Dwight’ as a F4:5 line. The line was tested for yield and other agronomic traits in 56 field environments and for resistance to 14 SCN populations in inoculated greenhouse tests. The line was released because it combines high yield performance with SCN resistance originating from plant introduction (PI) 437654. This PI 437654 source confers resistance to many SCN HG Types, especially HG Type 2.5.7 (equivalent to Races 1 and 5), which is becoming more common in the midwestern USA. LD00‐2817P has a relative maturity of 4.5 and is being released as a germplasm line because of its usefulness as a parent for soybean breeders developing new cultivars with HG Type 2.5.7 resistance.

Context‐Specific Genomic Selection Strategies Outperform Phenotypic Selection for Soybean Quantitative Traits in the Progeny Row Stage

“…In addition to the RILs and parents, three maturity checks were included: LD00-3309 (MG early-IV), 'LD00-2817P' (MG mid-IV) (Diers et al, 2010), and 'Ellis' (MG late-IV) (Pantalone et al, 2017). Soil type was primarily Shady loam (fine-loamy, mixed, subactive, thermic Typic Hapludults) and Shady-Whitwell (fine-loamy, siliceous, semiactive, thermic Aquic Hapludults) complex in Knoxville, Dickson (fine-silty, siliceous, semiactive, thermic Glossic Fragiudults) and Staser (fine-loamy, mixed, active, thermic Cumulic Hapludolls) silt loams in Springfield, and Loring (fine-silty, mixed, active, thermic Oxyaquic Fragiudalfs) and Routon (fine-silty, mixed, active, thermic Typic Epiaqualfs) silt loams in Milan.…”

Epigenome-wide inheritance of cytosine methylation variants in a recombinant inbred population

“…The two parental lines, LD00-2817P (Diers et al 2010) and LDX01-1-65 (Brucker et al 2005), were used to create the studied RIL population (see Supplemental Methods for additional information).…”

Identification of Quantitative Trait Loci Controlling Gene Expression during the Innate Immunity Response of Soybean

“…This study was conducted by testing plants of four soybean (Glycine max) genotypes with contrasting genes for resistance to soybean cyst nematode (LD00-2817P [Diers et al, 2010] and LDX01-1-65 [Diers et al, 2005]) or sudden disease syndrome caused by Fusarium virguliforme (Ripley [de Farias Neto et al, 2007] and EF59 [Lightfoot et al, 2005]), as well as the 97 F3:4 (here after called as F3) lines from a cross between LD00-2817P (Diers et al, 2010) and LDX01-1-65. The lines from the LD00-2817P by LDX01-1-65 cross are the same lines that were used to test combinations of soybean cyst nematode (Heterodera glycines Ichinohe) resistance genes from PI 437654, PI 88788, and Peking that were bred into LD00-2817 and from Glycine soja PI 468916 that were bred into LDX01-1-65 (Kim et al, 2011).…”

“…We found clear variation between soybean genotypes in their MAMP-triggered oxidative burst, as well as in the expression of MAMP-responsive genes. Based on this analysis and the availability of a well-characterized population of soybean lines, we chose two parental soybean genotypes, one with a strong MTI response (LD00-2817P; Diers et al, 2010) and one with a weak MTI response (LDX01-1-65; Diers et al, 2005). These two genotypes also show significant differences in pathogen susceptibility when infected after MAMP treatment.…”
