Abstract

Salinity is the most common and extensive soil problem in coastal rice production environments. Tolerance at the reproductive stage is the most crucial as it determines grain yield. An F mapping population was developed from two rice genotypes contrasting in tolerance: NSIC Rc222 (sensitive) and BRRI dhan47 (tolerant). Salt stress injury scoring was performed to evaluate the performance of every F individuals. In this experiment, no significant influence was established on salinity score on the productive and unproductive tillers per plant, number of filled, unfilled and total spikelets and yield. Correlation analysis between grain yield and Standard Evaluation System (SES) score was positive, which was unexpected as in general yield will be decreased with increasing salinity score. Therefore, SES scoring is not the ultimate indicator for concluding a variety either tolerant or sensitive.
