Objective:
The overall objective of this research is the creation of a single nucleotide polymorphism (SNP)-based genetic map of the soybean. The specific objective of this research is the analysis of SNP DNA marker data using JoinMap or similar genetic mapping software for the purpose of integrating new SNP DNA markers with the existing genetic linkage map of the soybean.

Approach:
Data will be supplied to the University of Utah that indicate the single nucleotide polymorphism (SNP) allele that is present in each recombinant inbred line (RIL) of each member of the University of Utah Minsoy x Noir 1 or Minsoy x Archer mapping populations. The SNP markers will be developed from unigenes and from other non-gene DNA sequence data including BAC ends, BAC subclones and SSR flanking regions. JoinMap analysis will be performed on these data in order to determine the position of the various SNP loci on the soybean genetic linkage map. This will be followed by further analysis to merge the genetic mapping data from the five populations that have been used to develop the most recently released version of the soybean genetic map. These populations include the USDA/Iowa State Univ. A81-356022 x PI468.916 map; the three University of Utah recombinant inbred line maps derived from crosses of Minsoy x Noir 1, Minsoy x Archer and Noir 1 x Archer, as well as the Univ. of Nebraska map derived from the cultivars Clark and Harosoy. The result will be consensus genetic maps of the 20 soybean chromosomes.
