Interpretive Summary: The completion and publication of the sorghum genome sequence led to advances in molecular genomics research for the species. However, the translation and leveraging of genomic discoveries in sorghum for practical use as DNA markers for crop improvement is still limited. As in many cereal crops, translational genomics is a critical key towards elevating yield and quality from current plateau values for sorghum. This presentation will focus on development and deployment of marker assisted rapid trait introgression for three sorghum traits to implement translational applications and enable marker assisted selection. The demonstration of the use of causal gene markers for the three traits resulting in effective selection will be discussed.
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, the utilization and deployment of DNA molecular markers in sorghum is still limited. Here, we focused on translational genomics to develop a marker assisted rapid trait introgression approach for three important traits to implement molecular breeding in sorghum including; grain number, leaf surface protective trait and brown midrib for improved ethanol conversion efficiency. Our research demonstrates the application of translational genomics and the use of causal gene markers for three traits for effective selection to accelerate genetic gain in sorghum.
