A simple testing method for salt tolerance was developed in order to improve the efficiency of selection in breeding procedures, as follows.
Young seedlings are transplanted to petri dishes filled with sand and moistened with salt solutions at four concentration levels. About 10 days later, the height of the cultured seedlings is measured and linear regression equations of plant height of the crops tested on the salt concentration index are derived. The linear regression coefficients of each crop are standardized in order to eliminate the difference in plant size under normal conditions. A smaller coefficient (absolute value) indicates a higher salt tolerance.
This testing method is recommended due to the small number of seeds required, the short duration of the test and the relatively high accuracy of the results. It is especially useful for breeding work for salt tolerance in which a certain number of materials has to be checked in a short period of time in order to select tolerant lines.
