 ABSTRACT

This work aimed to evaluate in the field the level of resistance of twelve (12) new rice genotypes (KBR2, KBR4, KBR6, KBR8, KBR9, KBR11, KBR12, KBR13, KBR15, KBR17, KBR28, KBR42) and yield losses due to rice blast caused by Magnaporthe oryzae in Burkina Faso. The experimental setup used was a randomized block with three (03) replications. The parameters evaluated were leaf and panicle severity, leaf and panicle incidence, grain yield and yield loss rate. Results showed that genotypes KBR15 and KBR17 were resistant to leaf blast at the Dî and Bama sites. Genotypes KBR12 and KBR13 recorded the best grain yields over the two production campaigns at the Dî and Bama sites respectively. Genotypes KBR28 and KBR42 recorded the highest 1000-grain weight and the lowest yield loss on both sites, respectively.
In view of these results, the KBR15 and FKR17 genotypes can be used as a means of varietal control of rice leaf blast in rice fields in Burkina Faso.
