Evaluation participative de variétés de riz dans les zones salées du Sénégal, Mali et de la Gambie

Abstract

Participatory Varietal Evaluation of Rice Varieties in the salt areas of Senegal, Mali and Gambia. This study is part of the STRASA project (Stress Tolerant Rice for Africa and South Asia) implemented by AfricaRice, in partnership with IRRI. One of its key components is the search of salinity tolerant rice varieties. The results are related to 5 participatory breeding trials conducted during one year in various salt conditions in Mali, Gambia and Senegal. The choice of the salt tolerant varieties by farmers confirmed by statistical analysis of agronomic parameters allowed to select the varieties with the best agronomic performances. The variance analysis of the interaction Genotype x Environment showed a significant effect on the grain yield and on the plant height. In each site, the agronomical performances of the varieties chosen by the farmers were confirmed by statistical analysis. These varieties are: IR 72593-B-3-2-1-2-B; IR 59418-7B-21-3 and WAS 73-B-B-231-4 in Senegal; IR 76346-B-B-10-1-1-1 and IR 65192-4B-11-3 in Gambia; and WAS 73-B-B-231-4 in Mali.
