Researchers from Biotechnology Laboratory Detail Findings in Botany (Evaluation Of Rice Genotypes Under Salt Stress At The Seedling And Reproductive Stages Using Phenotypic And Molecular Markers)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Life Science Research have been published. According to news reporting originating from Dhaka, Bangladesh, by NewsRx correspondents, research stated, "Salinity screening for 27 rice genotypes was performed at the seedling and reproductive stages respectively, in the hydroponic system and in sustained water bath. Three selected SSR markers were used to determine salinity tolerance in rice genotypes."

Our news editors obtained a quote from the research from Biotechnology Laboratory, "Phenotyping of the germplasm was done at EC 12dS/m and 6dS/m at seedling and reproductive stages, respectively. Based on modified standard evaluation score for visual salt injury at seedling stage, eight genotypes were salt tolerant, four were moderately tolerant and the rest fifteen were susceptible. At the reproductive stage, six genotypes were tolerant to EC 6dS/m whereas eleven of them were susceptible. SSR based marker identified seven genotypes as tolerant but ten of them were susceptible for all three markers compared to two checks. Six genotypes were tolerant in both phenotypic and SSR screening."

According to the news editors, the research concluded: "The indentified salt tolerant genotypes can be potential germplam sources for future breeding program."
