Results of the testing of common wheat variets from world collections for salt tolerance under irrigation conditions in Jizzakh region

Abstract

The environment in Uzbekistan is characterized by large amounts of heat, insufficient rainfall and saline soils. It explains the need to study the resistance of plants to abiotic stresses. The salt tolerance of plants is determined by their capacity to vegetate and produce satisfactory yields of economically valuable products in saline soils. The objective of the study was to test common wheat varieties for salt tolerance with subsequent selection of varieties with high tolerance to salinity. The testing of common wheat varieties for salt tolerance under irrigation conditions was carried out in Galla-аral Branch of Uzbek Research Institute of Grain and Legume Crops. At the first stage, the identification of 315 common wheat varieties was performed on Hosildor. The study revealed positive correlation coefficients in the weight of 1000 grains, number of nodal roots and length of coleoptile. 4 common wheat varieties with high salt tolerance under irrigation conditions were also selected.
