Project Activities

Genomic characterization of Senegalese and Nigerien landraces and breeding lines to connect West African germplasm to global sorghum breeding efforts.



Genotyping-By-Sequencing (GBS) is a next generation sequencing approach that facilitates quantitative and population genomics studies of crops. In this study, we performed sequencing on the West African Sorghum germplasm from Genbank and breeding lines using the GBS protocol according to Elshire et al. 2011. The objective is to identify the genomic regions and accessions that harbor alleles that are adaptive for particular regions or environments. Moreover, characterizing genomic variation (SNP diversity, population structure, and haplotype structure) West African accessions will be useful for genomics-enabled breeding in West Africa. Alongside the West African accessions, we also genotyped other global accessions and breeding lines from K-State. In addition, our GBS preliminary results revealed 158018 SNPs for 2996 samples.
