Research Project: NESTED ASSOCIATION MAPPING TO IDENTIFY YIELD QTL IN DIVERSE HIGH YIELDING SOYBEAN LINES - CONTINUED EVALUATION

Location: Soybean Genomics and Improvement

Project Number: 8042-21000-275-37
Project Type: Reimbursable

Start Date: Oct 01, 2012
End Date: Mar 31, 2014

Objective:
Identification of genes or Quantitative Trait Loci (QTLs) that positively impact soybean seed composition and yield, and 2) identification of DNA markers that soybean breeders can use to combine these genes or QTLs into new varieties more rapidly than is now possible.

Approach:
ARS will complete the genetic analysis of the 5,600 Nested Association Mapping recombinant inbred lines (RILs) and parents that have been developed earlier as part of this project. Single Nucleotide Polymorphism (SNP) DNA markers developed at the USDA, Beltsville will be used in this genetic analysis. The Cooperators at the Univ. of Illinois and the Univ. of Nebraska will evaluate the yield of the 5,600 RILs and parents in the field and the Collaborator at the Univ. of Nebraska will also evaluate seed composition (protein and oil) and seed size. The combined genotypic and phenotypic data will be used to identify genes/QTL that control soybean yield and seed composition.
