Abstract
Determining salt tolerance potential in wheat is one of the most important problems in breeding practice for areas with primary and secondary salinity. Presence of large areas of saline soils results in inhibition of growth, development and stability in obtaining high yields of agricultural plants. Therefore, there is a need for a comprehensive studying and improving of diagnostic methods during early growth stages. Different genotypes of wheat Triticum aestivum Host. and Triticum durum Desf. were used to identify salt tolerance markers. Both morphometric and some biochemical indicators of wheat varieties were used as salt tolerance markers. At this stage, it was shown that a comprehensive description of wheat varieties is needed to assess resistance of wheat varieties to chloride salinity.

Summary
Черные столбцы — контроль, серые столбцы — 150 мМ NaCl. Сорта пшеницы: 1 — Агата, 2 — Варяг, 3 — Дарья, 4 — Злата, 5 — Лиза, 6 — Оренбургская 13, 7 — Оренбургская 22, 8 — Оренбургская 233, 9 — Учитель, 10 — Эстер, — Жемчужина Поволжья, — Калач, — Мироновская 808, — Московская 39, — Оренбургская 10, — Оренбургская 21 При рассмотрении отдельно по сухому весу проростов все сорта пшеницы можно разделить на 3 группы — сорта с высокой чувствительностью к ионам натрия и хлора (Варяг, Оренбургская 13), устойчивые сорта (Агата, Жемчужина Поволжья, Лиза, Московская 39, Оренбургская 10, Оренбургская 233) и сорта с промежуточными параметрами чувствительности
