Abstract: Phosphorous insufficiency is the major constraint for rice yield. The increase in phosphorous fertilizer cost as well as the decline in rock phosphate reserves poses a greater threat in rice farming. Hence the development of phosphorous starvation tolerance cultivars found to be the best solution than application of fertilizers. Hydroponics experiment was carried out in 33 introgressed rice lines containing PSTOL1 gene along with parents to study their responses under phosphorous sufficient and deficient condition. Significant differences were observed for shoot length, root length, fresh and dry weights of root and shoot among the genotypes. Enzymatic activity was also differed significantly between genotypes of different genetic background but carrying phosphorous starvation tolerance gene. The present study showed the importance of selection of genetic background to exploit the potential of introgressed gene.
