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.
