Assessment of drought tolerance in some barley genotypes cultivated in West part of Romania

Abstract

In the present paper, we have taken into study a collection consisting of autumn barley in order to evaluate quantitative drought resistance criteria. The genotipe were tested in non stressed and stressed conditions. Some drought tolerance indices, Stress Tolerance Index (STI), stress tolerance (TOL), Stress Susceptibility Index (SSI) and Mean Productivity (MP) were used. The indices were adjusted based on grain yield under stress (Ys) and non-stress (Yp) conditions. There were significant differences for all criteria among the genotypes. The significant negative corelations of Ys with Yp, distinct significant and positive with MP, distinct significant and negative with TOL, ISS and distinct significant positive with STI.YP it was corelated distinct significant with MP. TOL,ISS. Genotypes were significantly different for their yield under stress and non-stress conditions. This study was conducted to assess the selection criteria for identifying drought tolerant genotypes and high-yielding genotypes in drought stress and non-stress conditions.
