Popis: Tomatoes (Solanum lycopersicum L.) are some of the most popular vegetables in the world. The productivity of crops is determined by a detailed knowledge of the natural environment, the correct application of the knowledge related to the specific technology, and the interaction between species and the environment. The environment itself influences the crops and they may be beneficial to the normal development of the plant or may induce different sensitivities to the cultivated plants. The main objective of this article was to identify the most resistant tomato varieties to Alternaria alternata attack, in natural and artificial infection conditions. The biological material used was five varieties of tomatoes with large-fruit: ‘San Marzano’, ‘Marmande’, ‘Romus’ and with cherry-type fruit: ‘Perun’ and ‘Bajaja’. The varieties were chosen due to large scale cultivation, resistance to various stress factors (disease and pest), and different organoleptic qualities. In the present events of climate change, it is necessary to continue testing the genetic material on the resistance and tolerance to the action of pathogens. The aim of the research was to test a group of tomato varieties to A. alternata attack. The pathogens can cause plant populations to evolve into an extremely varied set of immune receptors with differing ways of responding. In the Transylvanian Plain area, Romania, 2021 was a favourable year for this pathogen due to suitable infection conditions. Among the varieties of tomatoes, the cherry-type fruit ‘Perun’ (14.73%), was one of the most resistant to A. alternata. At the same time at the opposite end, the ‘Bajaja’ variety (25.33%) was the most affected cherry-type tomato in case of natural infection in 2022. The differences between the varieties reinforce the fact that climatic conditions significantly impact the dispersion of the pathogen on the field cultivated in both types of infection.
