Bacterial blight is one of the most devastating diseases in most rice growing regions and causes up to 50% of yield losses in west Africa. It is caused by different Xanthomonas oryzae pv. oryzae (Xoo) pathogen. Resistance to bacterial blight is controlled by both race-specific genes and quantitative trait loci with more 45 race-specific resistant genes (with the prefix Xa or xa for Xanthomonas) already reported in the literature (Neelam et al. 2020). AfricaRice evaluated 107 Oryza glaberrima accessions for their reaction to four Xoo strains (isolates) originated from Burkina Faso (BAI3 and BAI4), Mali (MAI1), and the Philippine (PXO86) under greenhouse conditions (Djedatin et al. 2011). Although none of the accessions were resistant to either of the two highly virulent strains from Burkina Faso, there were some accessions that were resistant to the two strains originated from Mali and the Philippines. Here, we compiled list of the most promising O. glaberrima landraces (accessions), which could be used as donors in developing bacterial blight resistant rice germplasm in Africa.
