Interpretive Summary:

Technical Abstract: The application of genomics through molecular breeding holds great promise to enhance genetic gain for yield and other important agronomic traits of sorghum. However, current utilization and deployment of DNA molecular markers in sorghum is still limited. Here, we report our studies on translational genomics to develop marker assisted rapid trait introgression approach for various critical agronomic traits of sorghum. Results from these studies have led to efficient and timely introgression of positive alleles in elite backgrounds. Some traits of interest include: leaf surface protective trait, brown midrib for improved ethanol conversion efficiency, thermal stress response and improved grain number. Our research demonstrates the application of translational genomics and the critical need for continuous identification of causal gene markers for agronomic traits for effective selection to accelerate genetic gain in sorghum.
