Soy Breeding Tools and Approaches Identified Through Stakeholder Collaborative Research Effort

The SoyaGen Project aimed to develop genomics-derived solutions to real-world challenges faced by breeders. In its conclusion, the project team documented new tools and approaches that breeders can use to implement molecular, genomics-informed breeding strategies that are broadly applicable to global soybean breeding efforts.

The project was a collaboration among Canadian soybean researchers and breeders from the academe, the private sector, and international partners. The project enabled them to focus on maximizing soy yield through optimization of maturity and improved disease resistance. Specifically, they were able to identify single nucleotide polymorphism (SNP) datasets that exhibited the genetic diversity of a cultivated soybean from a collection of more than a thousand soybean accessions as well as a subset of 102 short-season accessions. They also identified SNP markers for selecting favorable alleles at key maturity genes and loci associated with increased resistance to significant pathogens and pests. The researchers were also able to develop a diagnostic tool that helped them identify and map specific pathotypes of Phytophthora sojae. Lastly, they came up with a genomic prediction approach to determine the most promising combination of soy parents for breeding.

Aside from the scientific contributions to soy breeding, the project also demonstrated a model for collaborative research that can be replicated for other research activities involving other crops. The collaborative effort has proven to help stakeholders and breeders address challenges such as increasing agricultural productivity in the midst of climate change.
