| Abstract | In order to have a consistently high yield rate of lettuce in the right-bank forest-steppe of Ukraine, it is necessary to control the varietal renewal of the culture and select highly productive and adapted to the soil and climatic growing conditions. Therefore, a comparative assessment of phenological data, basic biometric indicators and productivity and yield of new varieties of Lactuca sativa L. of foreign selection was carried out. The article presents the results of phenological observations of plant development, their biometric indicators. Productivity and yield level were determined depending on the variety. The suitability of the researched varieties of lettuce of foreign selection for cultivation in the conditions of the right-bank forest-steppe of Ukraine was established. The mass of the productive part of the plant according to the experiment variants varied on average over the years of the study in the range of 345–685 g. The Aveleda and Annisol varieties were more productive. The Ligier variety turned out to be the least productive – 353 g. The Snowflake variety, which was chosen as a control, took an intermediate position among the experimental variants in terms of plant weight with an indicator of 385 g. The type of leaf lettuce affects its productivity and yield, and the deviation from yield control can be up to 19.9 t/ha in the upward direction and up to 4.4 t/ha in the downward direction due to the variety. Aveleda and Annisol varieties produced higher yields – 59.2 and 62.6 t/ha. These varieties provided the greatest increase in yield in relation to the control. Ligier and Brietta varieties had the lowest yields over the years of research. Therefore, the researched varieties of leaf lettuce of foreign selection turned out to be fully adaptable to the conditions of the growing zone and preserved the morphological features and biological features of the plants. | ||
