Research Project: Utilizing Unique Genetic Diversity to Combine Elevated Protein Concentration with High Yield in New Varieties and Experimental Lines

Location: Soybean/maize Germplasm, Pathology, and Genetics Research

Project Number: 5012-21000-029-14-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2018
End Date: Aug 31, 2019

Objective:
Develop and release experimental lines and varieties that are higher in protein concentration and higher in yield than current varieties; Characterize high protein sources for the presence of the major protein quantitative trait loci (QTL) on chromosomes 15 and 20; and, Characterize protein composition and amino acid profiles of G. tomentella-derived lines and selected experimental soybean lines; and Improve seed quality in early planting soybean production system (ESPS).

Approach:
To increase yield and protein simultaneously requires a more productive plant. Our unique genetic diversity for high yield provides ARS with the genetic capacity to increase both to an extent not possible with the conventional gene pool. ARS can do this by targeting ARS breeding populations derived from exotic germplasm with higher protein concentrations, crossing ARS highest yielding experimental lines with germplasm with higher protein concentrations, and analyzing more ARS experimental lines earlier in the testing process for composition than ARS has done in the past.
