Formation of a model of lettuce (Lactuca sativa L.) variety of the Batavia type for hydroponic cultivation

Relevance. Currently, there is a tendency to increase the volume of lettuce cultivation in hydroponics. Such specific conditions for growing lettuce hydroponically as high humidity in the root zone, different levels of illumination throughout the year and specific mineral nutrition, dictate a number of necessary characteristics that varieties should possess. In addition, the lettuce variety for hydroponics should consistently give high yield and have good consumer qualities. Accordingly, it is necessary to carry out selection separately for specific hydroponic conditions. And for theoretical justification of the selection of lettuce varieties for this technology and increasing the efficiency of the breeding process, it is necessary to form a model of the variety, which was the goal of this research.
