Probit Analysis and Heritability of Salinity Tolerance in Agropyron desertorumGenotypes

Germination ability and salt stress tolerance of Agropyron desertorum were evaluated using ten genotypes originally collected from different areas of Iran in greenhouse condition. Five different concentrations of NaCl solution were used in this experiment. Analysis of variance showed considerable variation in all the germination attributes under salinity stress. Principal component analysis revealed that first and second components accounted for about 97.6 percent of the total variation among the traits studied. The first component included root length, plumule length, seedling length and seed vigor and accounted for 62.3 percent of the total variation among the traits. This component entitled as the seed germination ability. Hierarchical cluster analysis classified the genotypes in three groups. In conclusion, selection for the higher amounts of the traits root length, plumule length, seedling length and seed vigor can improve the seed germination ability and salinity tolerance in Agropyron desertorum genotypes at the seedling stage in greenhouse condition. Furthermore, crosses between the genotypes classified in the clusters 1 and 3 causes to broadening genetic variation and possibility of the efficient selection among the progenies obtained from these crosses
