Registration Of Wyandot X Pi 567301b Soybean Recombinant Inbred Line Population

A soybean [Glycine max (L.) Merr] mapping population, Wyandot x PI 567301B (Reg. No. MP-5, NSL 519221 MAP), consisting of 357 F-7-derived recombinant inbred lines (RILs) was jointly developed by the USDA-ARS and the Ohio Agricultural Research and Development Center in Wooster, OH. The population was developed by single seed descent from a cross between 'Wyandot' and PI 567301B. Wyandot is a food-grade cultivar released by The Ohio State University, and PI 567301B is a plant introduction from China that differs from Wyandot for many morphological traits. PI 567301B was also confirmed to carry resistance to seed and seedling root rot, powdery mildew, and the soybean aphid. We have used this population to map quantitative trait loci (QTL)/genes for nine traits. The 357 RILs were genotyped using BARCSoySNP6K BeadChips, and a high density linkage map with 2545 single nucleotide polymorphism (SNP) markers well distributed on the 20 chromosomes of soybean was constructed and recently published. This mapping population is among the few biparental soybean mapping populations featuring high-resolution genetic maps. We believe that the genetic map, population, and phenotypic data we provide will be an excellent resource for teaching labs in plant breeding and genetics as well as in discovery of new QTL.
