abstract: Accounting for population structure to minimize
spurious associations in association analyses is of
crucial importance. With sorghum genomic sequence
information being available, there is a growing interest in
performing such association studies for a number of
important agronomic traits using a candidate gene
approach. The aims of our study were to conduct a systematic
survey of molecular genetic diversity and analyze
the population structure in cultivated sorghum [Sorghum
bicolor (L.) Moench] accessions from West Africa. Our
analysis included 219 West African cultivated sorghum
accessions with differing maturity intended for a markertrait
association study. A total of 27 SSRs were used, which
resulted in detection of 513 alleles. Genetic diversity estimates
for the accessions were found to be high. The
accessions were divided into two subgroups using a modelbased
approach. Our findings partly agree with previous
studies in that the guinea race accessions could be distinguished
clearly from other accessions included in the
analysis. Race and geographical origin of the accessions
may be responsible for the structure we observed in our
material. The extent of linkage disequilibrium for all
combinations of SSRs was in agreement with expectations
based on the mating system.
