Analysis of population structure and genetic diversity reveals gene flow and geographic patterns in cultivated rice (O. sativa and O. glaberrima) in West Africa por Yelome, O.I., Audenaert, K., Landschoot, S., Dansi, A., Vanhove, W., Silué, D., Damme, P. van, Haes, G.

“…Germplasm structure showed that Oryza sativa accessions were not totally isolated from Oryza glaberrima accessions. The results allowed identification of five O. glaberrima accessions which grouped together with O. sativa accessions, sharing common alleles of 18 loci out of the 20 SSR markers analyzed. …”

Genetic variation and population structure of the rice accessions maintained in the AfricaRice genebank using DArTseq por Gouda, A.C., Sangare, J.R., Gnikoua, K., Wambugu, P., Huggins, T.D., Ndjiondjop, Marie-Noelle

“…In the present study, we comprehensively characterized a collection of 9013 accessions, including Oryza barthii A. Chev., Oryza glaberrima Steud., Oryza longistaminata A. Chev. & Roehr., Oryza sativa L. ssp. indica, and Oryza sativa L. ssp. japonica, for genetic diversity and population structure using genotyping-by-sequencing through DArTseq analysis. …”

History and progress in genetic improvement for enhancing rice yield in sub-Saharan Africa por Futakuchi, K., Senthilkumar, Kalimuthu, Arouna, A., Vandamme, Elke, Diagne, M., Zhao, D., Manneh, B., Saito, Kazuki

“…Among these varieties, the most well-known are interspecfic upland rice varieties “New Rice for Africa (NERICA)” that were developed from crosses between improved Oryza sativa tropical japonica and Oryza glaberrima varieties. However, recent field assessements demonstrated that upland rice yield can be further improved through introduction of upland indica materials from Asia. …”
