Özet
Low-temperature-induced crop loss is one of a major threat in rice production; introduction of cold tolerant trait from cultivars that are well adapted to cooler climates is considered a vital strategy to mitigate the crop loss. In this study, twenty geno-types obtained from Trakya Agricutural Research Institute, in Turkey were evaluated for their reproductive stage cold tolerance in order to identify best performers for African cold-prone rice growing ecologies. The genotypes were first screened in temperature regulated screen house at AfricaRice research station in Tanzania, then field evaluated in Madagascar at the elevation of 1650 meter above sea level in rainfed lowland ecology. The genotypes showed range of reactions for the cold stress from highly susceptible to highly tolerant level. The susceptible genotypes showed consistent delay in flowering date up to 20 days, height reduction up to 40% and spikelet sterility up to 100% and consequently yield loss up to 100%. Nevertheless, in the field trial six genotypes; namely: Meric, Surek-95, Serhat-92, Duragan, Negis and Halilbey were identified to have superior performance compared to the local cold tolerant checks, with the yield potential of more than 5 t/ha. These candidate genotypes can be used to expand rice production in cold prone areas and contribute to food security in Africa.
