Although Romania's climate is known as "moderate continental", in recent years extremely large variations have occurred (total amount of precipitation from one year to another, its distribution throughout the year), which determines water deficits frequently associated with heat during the growth and development of wheat on the chernozem of Caracal. To study the variability of some of the characters involved in drought resistance of winter wheat, 220 common wheat varieties of different origins were used. The presentation of the pluviometric regime was made based on the Angot index, an index that expresses how rainy the month is in relation to the overall precipitation in a year.
The frequency of months was determined according to the drought intensity classes. Based on the average yields obtained in the period 2020-2024, a restricted common assortment was established. Starting from this, were analyzed the relationship between the average yield and the Angot index, the reaction of varieties to contrasting water supply conditions, the interaction of temperatures x precipitation in the May-June period (Triboi model, 2008) and the influence of water stress on production, productivity elements (number of grains/ear, weight of grains/ear, TKW) and production quality (TW, protein).
