Molecular genetics markers associated with salt tolerance in grain sorghum

ABSTRACT

The present study was carried out to evaluate two inbred lines of grain sorghum for their environmental stress tolerance [salinity] at the field. These two inbred lines were chosen as salt tolerant [ATX631] and salt sensitive [ICSR89038] for hybridization to obtain the F[1] generation and then selfed to obtain the F[2] generation. These contrasting genotypes and their F[1] and F[2] generations were utilized to detect DNA-based molecular markers associated with salt tolerance via RAPD and ISSR techniques, following the bulked segregant analysis. This analysis revealed some genetic markers associated with salt tolerance in grain sorghum that can be utilized during breeding programs via marker-assisted selection
