Scientific Objectives and Experimental Design


The TERRA-REF project is phenotyping the same genotypes of sorghum at multiple locations


Whole genome resequencing is being carried out on ~400 sorghum accessions to understand the landscape of genetic variation in the selected germplasm and enable high-resolution mapping of bioenergy traits with genome wide association studies (GWAS). Additionally, ~200 sorghum recombinant inbred lines (RILs) will be characterized with ~400,000 genetic markers using genotyping-by-sequencing (Morris et al., 2013) for trait dissection in the RIL population and testcross hybrids of the RIL population.

Three hundred thirty one lines were planted in 2016. Plantings occurred both under and west of the gantry system.
