“…The value of each variety is determined by its plasticity and stability, or the ability to form a certain level of yield in different environmental conditions [8][9][10][11][12][13][14]. It is important to take into account the different reaction of varieties on changes in conditions when choosing the place and cultivation technologies, which allows to best realize their genetic potential.…”

The aim of the study was to establish correlations between the main traits of grain productivity and quality, as well as evaluate collection samples of winter triticale for plasticity and yield stability. Material and methods. The research was conducted during 2017-2019 at the NSC "Institute of Agriculture of NAAS" (Ukraine, Kyiv region). The objects of the study were collection samples of winter triticale. During the study were used field, laboratory, measuring-weight and mathematicalstatistical research methods. Main results. Correlation analysis showed a strong positive relationship between the weight of grain from the plant with the weight of grain from the ear (r = 0.78), the average -with the number of grains from the plant and ear and the weight of 1000 grains (r = 0.47; 0.63 and 0.37) and weak -with starch content (r = 0.14). A negative correlation of the average strength was found with the protein content in the grain (r = −0.37). It was found that there is a weak positive correlation between the starch content and the weight and number of grains, which proves the possibility of creating forms with high grain productivity and high starch content. The most favorable conditions for the formation of high grain yields (average collection 4.97 t/ha) was in 2017, and the worst -in 2019 (4.09 t/ha). The studied varieties and samples were different in the level of plasticity and stability.

Purpose. To carry out an analysis of the ecological plasticity and stability of the characteristics of productivity, starch content, dry matter and to determine the parameters of ecological adaptability of potato varieties based on the characteristic “yield” in the soil-climatic zones of the Forest-Steppe and Polissia. Methods. The following methods were used in the research: laboratory, computational and statistical; to draw conclusions – analysis and synthesis. Results. The results of the analysis of potato varieties grown in different soil and climatic zones of Ukraine in terms of yield, starch and dry matter content are given. Promising varieties for selection and practical use with high indicators of adaptability, stability and plasticity were identified. It was found that the highest productivity results were obtained for the variety ‘RANOMI’ in the Forest-Steppe and Polissia zones – 34.6; 28.2 t/ha and high adaptability potential – 1.28; 1.27. The varieties ‘RANOMI’, ‘Cherie’ performed best in the Forest-Steppe zone with yields of 34.6 and 31.4 t/ha, in Polissia conditions – the varieties ‘RANOMI’, ‘PARADISO’ – 28.2 and 27.4 t/ha. The varieties with high plasticity were distinguished by starch and dry matter content (‘7 FOUR 7’, ‘PARADISO’, ‘FONTANE’, ‘RANOMI’, ‘LAUDINE’), productivity (‘7 FOUR 7’, ‘Rodriga’, ‘ALOUETTE’, ‘PARADISO’, ‘LAUDINE’). The varieties ‘Mysteriia’, ‘7 FOUR 7’, ‘LAUDINE’, ‘FONTANE’ and ‘LAUDINE’ proved to be very stable in terms of productivity and the varieties ‘Mysteriia’, ‘7 FOUR 7’, ‘Rodriga’, ‘PARADISO’, ‘RANOMI’ in terms of dry matter and starch content. The varieties with the highest productivity were ‘Rodriga’, ‘PARADISO’, and for dry matter and starch content – ‘FONTANE’, ‘LAUDINE’. Conclusions. In different soil and climatic zones, highly plastic varieties were selected according to yield index – ‘7 FOUR 7’, ‘Rodriga’, ‘ALOUETTE’, ‘PARADISO’, ‘LAUDINE’, according to starch and dry matter content – varieties ‘7 FOR 7’, ‘PARADISO’, ‘FONTANE’, ‘RANOMI’, ‘LAUDINE’. It was found that on average for 2019–2020 the highest productivity and high adaptive potential in the Forest-Steppe and Polissia zones had the variety ‘RANOMI’ – 34.6; 28.2 t/ha, respectively, CA – 1.28; 1.27. In the Forest-Steppe zone it is worth mentioning the varieties ‘Cherie’, ‘Rodriga’ with average CA index 1.15; 1.12 and productivity – 31.4; 30.62 t/ha, in the Polissia zone – ‘PARADISO’, ‘Rodriga’ with CA value – 1.20; 1.11 and productivity – 27.4; 25.5 t/ha.
