The research was conducted in Tartous Governorate during the two agricultural seasons (2018-2019 and 2019-2020) under control conditions, the aim of the research is to study the relationship between the productivity of five promising strains of bread wheat (‘ACSAD 1256’, ‘Douma 58847’, ‘Douma 58585’, ‘Douma 64453’, ‘ACSAD 1149’) and two cultivars (‘Douma 2’ and ‘Douma 4’) and some quantitative indicators of drought: stress tolerance index (STI), mean of productivity (MP), modified stress tolerance index (MSTI), and relative yield (RY). Cultivation was carried out in pots filled with light sandy silty soil, and three treatments of 70, 50, and 30% of the field capacity were applied in addition to the control and with three replications for each treatment. The strains ‘Douma 58585’ and ‘Douma 58847’ gave high yield values for grain in the two agricultural seasons. It was also found that there were significant differences between the two seasons in yield between the control and drought stress factors and drought tolerance indicators, such as stress tolerance index, modified stress tolerance index (MSTI), mean of productivity (MP), and relative yield (RY). On the other hand, a positive and strong relationship was found between STI, MSTI, and MP in both treatments and both seasons. The research concluded that the best indicators, which were related to the productivity, whether in the control or transactions and in the two growing seasons together, are STI and MP, which are promising indicators in the classification of stress-tolerant cultivars or strains.

Kluczowe informacje potrzebne do podejmowania działań w celu minimalizacji skutków suszy daje monitoring zjawiska. Do oceny zagrożenia suszą stosuje się wskaźniki, które pozwalają na określenie prawdopodobieństwa wystąpienia suszy, z uwzględnieniem jej rodzajów. Dla lokalnej i dokładnej oceny tego zjawiska stosuje się wskaźniki regionalne (opad, temperatura, wilgotność, usłonecznienie). W artykule omówiono różne wskaźniki stosowane w opisie i prognozowaniu susz. Przedstawiono także zasady organizacji monitoringu tych zjawisk.

Drought monitoring provides key information necessary for taking action in order to mitigate the consequences of this phenomenon. The risk is assessed using indicators which allow for determining the probability of drought occurrence, taking into account the drought type. Local, precise assessment of this phenomenon is based on regional indicators (precipitation, temperature, humidity, insolation). The article discusses different indicators used in drought description and forecasting. It also presents the rules for organisation of the monitoring.

Na bazie zebranych materiałów dokonano przeglądu obecnego stanu monitoringu zjawiska suszy w Polsce i na świecie. Stwierdzono, że monitoring zjawiska suszy stosowany jest przez wiele różnych ośrodków, wykorzystujących często do oceny jej intensywności te same wskaźniki i metody. Niestety, pomiędzy tymi ośrodkami brakuje wymiany informacji dotyczacych wyników badań. Pocieszający jest jednak fakt, że stan monitoringu suszy w Polsce i na świecie poprawił się znacznie po silnej suszy z 2003 r. i wciąż wprowadzane są nowe metody, umożliwiające dokładną prognozę tego zjawiska.

A survey has been carried out on the basis of the compiled materials. It concerned the current condition of drought monitoring in Poland and all over the world. It was stated that the drought monitoring was used by many different research centres which applied the same indicators and methods in order to estimate the drought intensity. Unfortunately, there is lack of information exchange concerning the research results between the centres. However, the condition of the drought monitoring in Poland as well as in the world has improved significantly after the intense drought of 2003 and still there are new methods being introduced, enabling more accurate phenomenon forecast.
