Intravarietal selection for salt tolerance in rice


, : Intravarietal selection for salt tolerance in rice. Pakistan Journal of Soil Science 6(1-2): 13-16

Three salt tolerant genotypes, grown in pots containing soil at 4 salinity levels (ECe values of 1.8, 5.8, 9.1 and 12.0 dS/m), showed decreased number of tillers/plant and grain and straw yield/plant with increasing salinity. IR6 had the greatest number of tillers/plant and grain yield at the highest salinity level. For each genotype large intravarietal variation in grain yield was observed at each salinity level.
