[Genetic control of NaCl tolerance in seedlings of durum wheat Triticum durum Desf. accessions].
The genetic control of tolerance to NaCl (0.7 MPa, 9.8 g/l) was studied in six durum wheat accessions from the world collection of the Vavilov Institute of Plant Industry. Analysis of F1, F2, and F3 of the crosses between tolerant forms and a in accessions k-17227 and k-10930 susceptible tester has demonstrated that a high salt tolerance is determined by one dominant gene; in accession k-46660, by three independent dominant genes; and in accessions k-l5305 and k-41884, by single genes without dominance effect. Potential allelism of the salt tolerance genes has been studied for the accessions with monogenically determined salt tolerance, and either identity or tight linkage of the genes determining salt tolerance of accessions k-15305 and k-41884 has been demonstrated. Provisional designations Tsa1, Tsa2, and Tsa3 are proposed for the genetic factors determining salt tolerance of accessions k-10930, k-17227, and k-15305, respectively.
