Ecological stability and plasticity of potato varieties under the conditions of the Right Bank Forest-steppe of Ukraine
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 101, Issue
Abstract
The article highlights the results of the study of the adaptive capacity of potato varieties under the conditions of the Right Bank Forest-steppe of Ukraine. It has been found that the most intensive variety of potato is Nadiyna variety(45.4 t / ha), which dominated in six-year-long yield tests. Slovianka, Malynska and Nadiyna varieties stood out in their high plasticity, the regression coefficients of which were 5.30, 3.80 and 2.45, respectively. According to the calculated regression parameters (bi = 0.42 and 0.43), Dyvo and Legend varieties responded poorly to changes in environmental factors. All the varieties under study are characterized by negative values of plasticity coefficients, which indicates a negative influence of certain biotic and abiotic factors on their productivity
