Abstract
Salinity is considered as one of the most important abiotic stresses limiting crop production. Among crop indigenous rice are known to survive under this stress. In this content, the present study was carried out to analyze genotypic variations in different salt tolerance of indigenous rice at germination and early seedling growth. The seeds of eleven indigenous (aman) rice genotypes and four salt concentrations (distilled water, 5, 10, 15dSm-1) were used as salt treatments. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Results showed that with the increase in salinity levels, germination parameters (germination percentage, germination energy, germination capacity, germination speed and seedling vigor index) and seedling growth parameters (seedling growth rate, shoot length, root length, dry weight) were decreased. The seedling growth parameters are relatively more sensitive to salinity than the germination parameters. Among the genotypes, Nara Jamai naru was superior to others considering germination parameters and growth parameters. In case of 5, 10dSm-1 Nara Jamai naru should comparatively better performance than other genotypes.
