Drought is one of the most important abiotic stress factors and depending on the season it can seriously limit wheat production. Breeding for drought tolerance is becoming a more and more important challenge in case of crop plants, notably in wheat. The breeding process includes the characterization of the basic breeding materials in aspect of performance under well-watered and drought stressed conditions. In our experiments we set up a complex stress diagnostic system in the greenhouse of the Cereal Research Non-profit Company where we could analyze the responses of different winter and spring wheat cultivars to drought. Wheat plants were grown under ideal water regime (watering to 60% of the 100% soil water capacity) and under drought stress conditions (watering to 20% of the 100% soil water capacity). The effect of water withholding on plant growing was tracked by a digital imaging system on the basis of number of plant pixels. After harvesting, plant heights, spike lengths, grain numbers and total grain weights were measured and values of well-watered and stressed plants were compared. Here the measured parameters of two drought tolerant (Sardari, GK 11-05) and two drought sensitive (Kärtner Früh, Jing 411) wheat genotypes are presented to prove the competence of our system in characterizing drought tolerance of wheat plants.
