In this study, we genotyped rice samples from Burkina Faso using the C6AIR SNP (Single Nucleotide Polymorphism) array (IRRI), including 27 registered cultivars and 50 rice samples collected in rice fields from three geographical zones in western Burkina Faso. Most of the registered cultivars clustered with the indica genetic group, except seven assigned to japonica and one admix. All but one of the rice samples from farmers' fields belonged to the indica group. The other field sample, which unexpectedly clustered with the Aus genetic group, originated from a rainfed lowland site known to differ in terms of agronomic practices, and which revealed to be highly differentiated from the five other sites. Apart from this peculiar site, the rice grown in irrigated areas did not differ from rice sampled in rainfed lowlands. Finally, obtained genetic data confirmed the high frequency of one cultivar, in congruence with farmers' interviews. We argue on the importance to document and preserve the high agro-biodiversity observed in rice from Burkina Faso as a prerequisite to face the current challenges of growing rice demand and global change. specialized BURKINA FASO 076 020 1 3 129-141 2021 2673-7655 https://www.documentation.ird.fr/hor/fdi:010083579 10.3390/crops1030013 2673-7655 [F B010083579] https://www.documentation.ird.fr/hor/fdi:010083579 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-11/010083579.pdf IRD - Base Horizon / Pleins textes 2021-11-03 2025-02-24 fdi:010083579 fre
