Morphological Evaluation Of Rice Genotypes For Salinity Tolerance Under Hydroponics

Abstract

Salinity, a prominent abiotic stressor, profoundly influences the growth and development of rice plants. In this study, 26 genotypes, accompanied by two control varieties, underwent screening for salinity tolerance at the seedling stage through hydroponics. Analysis of variance unveiled significant variations among genotypes in the recorded traits. Unlike many studies that assess salt tolerance based on individual trait means, our approach utilized membership function values, encapsulating cumulative tolerance across all traits. The identification of highly tolerant and tolerant genotypes in this study suggests their potential for enhancing salt tolerance during the seedling stage in rice through targeted breeding efforts.
