Participatory varietal screening, selection and testing of a large number of salt tolerant
varieties/genotypes of rice were conducted at Central Soil Salinity Research Institute, Regional
Research Station, Lucknow, India during 2001 to 2007. This is aimed to identify and develop a high
yielding, adaptable and acceptable rice variety for sodic soil environment through farmers’ participatory
approach. Generally plant breeders tend to develop varieties through centralized breeding method are
popular among farmers at favorable rice production system and often they are not suitable for stressed
environments. A large number of varieties/genotypes were screened and evaluated under researchers
managed on-station trials during 2001. From 2002 to 2005, farmers became a part of the varietal
selection and testing process in order to incorporate their preferences. In this direction variety CSR 36
and genotype CSR-89IR-8 not only performed better in different locations, but was also deeply
appreciated and adopted by farmers in sodic areas consistently over years. It can withstand sodicity
tolerance up to pH2 ~ 9.9 and gives higher grain yield performance than other varieties/genotypes
tested. The selected varieties/genotypes were evaluated under farmers managed baby trials during 2006
to 2008 and compared with traditional varieties. Based on the farmer’s preference, grain yield, farmer to
farmer seed dissemination and large scale adoption in the target environment, the genotype CSR-89IR-8
has emerged as the best genotype and released as a variety named CSR 43 by the State Variety Release
Committee in 2011. The success of PVS in the sodic environments convinced researchers, stakeholders
and partner organizations for adopting this approach for rice variety development and larger impact
particularly under resource poor and salt affected conditions.
