Interpretive Summary: Genetic gain and breeding efficiency for sorghum is lagging compared to rice or corn. One possible reason is the limited deployment of molecular breeding in sorghum. In this study, we integrated the three D’s (discovery, development and deployment) of translational genomics to develop a marker assisted rapid trait introgression approach for three important traits to implement molecular breeding in sorghum. We will describe and provide examples of application of translational genomics to demonstrate the use of causal gene markers for three traits for effective selection in a breeding workflow to accelerate genetic gain in sorghum.

Technical Abstract: Application of genomics through molecular breeding holds great promise to help improve the rate of genetic gain for yield and other important agronomic traits of sorghum. However, the utilization and deployment of molecular breeding in sorghum is still limited. In this study, we integrated the three D’s (discovery, development and deployment) of translational genomics to develop a marker assisted rapid trait introgression approach for three important traits to implement molecular breeding in sorghum. We will describe and provide examples of application of translational genomics to demonstrate the use of causal gene markers for three traits for effective selection in a breeding workflow to accelerate genetic gain in sorghum.
