Rice lines were screened for salinity tolerance at International Rice Research Institute. Out of eighteen lines , eight were found tolerant, five were moderately tolerant and rest were susceptible to high salinity. Two entries showed higher root shoot ratio and were also found tolerant. Screening at seedling stage and higher root shoot ratio provides a clue about salt tolerance potential of a genotype. |

Eighteen rice genotypes were grown in lysimeters with or without salinity (8.5 dSm-1) upto maturity. After 90 days of sowing three upper leaves of ten plants of each genotypes from each treatment and replicate (three replication) were excised and their leaf area and chlorophyll content were estimated. At maturity yield per plant was also recorded. The yield per plant, leaf area and chlorophyll contents of all the genotypes reduced by salinity. However, genotypes J-349, J-349 x Bas-385, NIAB-6, NR-I, RST-1-86 and RST-24 showed better performance than others. Positive correlations were found between grain yield per plant and chlorophyll contents. |

Concerted breeding efforts on rice improvement at NIAB has resulted in the development of a salt tolerant, high yielding variety derived from IR-6 through irradiation. Preliminary evaluation for salt tolerance was done at University of Agriculture, Faisalabad. Three years multilocational yield trials were conducted in saline soils. Based on higher yield potentials, fine grain and salt tolerance, the NIAB-6 was approved under the name Niab-Irri-9` in 1999 by the Punjab Seed Council for general cultivation in the province.
