Soybean Project

A web-based pedigree database to support soybean breeding efforts

Welcome to soybean system

Objective: Develop a web-based soybean pedigree lineage interface and build a soybean pedigree database to help breeders make their crossing and selection decisions and improve soybean breeding efficiency.
Project background:
Soybeans are the world's largest source of vegetable protein and the second largest source of vegetable oil. The United States is the leading soybean producer and exporter in the world (USDA, 2012). The narrow genetic base in U.S. soybean breeding is a major limitation to the rate of yield improvement. Therefore, selecting diverse high-yielding parents and developing high-yielding soybean cultivars will improve the rate of genetic gain in Arkansas as well as in the USA.

Project Background

Over 700 soybean public varieties have been released in the U.S. in past 70 years and many breeding lines are generated each year in a soybean breeding program. However, with complicated pedigrees and availability of breeding lines for selection, one of main challenges for the soybean breeders in a soybean breading program is how to select parents to make crosses, which give highest probabilities to generate the best breeding lines. Moreover, during the parental selection process, the breeders also want to know if the lines they select carry the desired agronomic traits and have the desired marker haplotypes for the traits of importance.

Project Aim

This project is to intend building a pedigree database including all U.S. cultivars and experimental lines from soybean breeding programs to allow the soybean breeders to quickly view the pedigrees of their breeding lines and phenotypic information for the desired agronomic traits, and to select appropriate lines to make crosses. In addition, this database will also incorporate DNA marker data to help breeders make their decision. The database can also be used for soybean geneticists to understand the pedigree linage and population structures in their genetic studies.
