Abstract

Salinity presents a major challenge to agriculture, negatively impacting crop growth and yield in different ways. As a result, various strategies have been implemented to handle the problem of low productivity. The cultivation of salt-tolerant crops represents a practical solution for achieving profitable yields in saline regions, emphasizing the need for a rapid method to screen for salt-tolerant genotypes, especially in their early growth stages. Consequently, a seed germination test was conducted to assess parameters such as germination percentage, root length, shoot length, fresh weight and dry matter production to identify the salt-tolerant sorghum genotype. The findings indicate that the sorghum genotypes G34 (IS6710), G48 (IS19159), G1 (IS6312), G50 (IS6316) and G2 (IS6313) exhibited tolerance to elevated salt concentrations. These physiological parameters can effectively screen large sorghum germplasm collections, facilitating the identification of salt-tolerant lines suitable for cultivation in saline regions.
