Rice Research Station - Labuduwa

Labuduwa Research Station is one of the satellite station of Rice Research and Development institute, Bathalagoda. It is located at Labuduwa, Akmeemana of Galle District. Command Area of the station is wet zone rice field belongs to WL1 and WL2a agro ecological zones. RRS, Labuduwa is the main rice breeding Station of Low Country Wet Zone of Southern Province of Sri Lanka.  From 1971 up to now the station has released eight rice verities belongs to different age classes namely Ld 66 (1971)Ld 356 (1994)Ld 365 (2008)Ld 368 (2011)Ld 408 (2010)Ld 371(2014)Ld 253(2016). Presently station is contributed for the national seed production by providing breeder seeds of five released varieties Ld 365Ld 368Ld 408Ld 371 and Ld 253. Further research on improving the productivity and pest diseases tolerance, abiotic stress tolerance and quality of rice is going on. Apart from the breeding research, plant protection and soil and agronomy research carried out with respect to the problems associated with pest and diseases, soil and climate conditions of the low country wet zone. Meteorological data collection and dissemination of knowledge with respect to all the disciplines rendered through publications, training of graduate, diploma and school students, field days, radio programs ect. Solving of farmer problems and educating extension officers related to new technologies carried out frequently.

Mandate of the Center is to develop high yielding rice verities for high potential mineral soils of the low country wet zone rice lands and generation and dissemination of related technologies.
