Project Leader: Ihor Mykolayovych Kovalenko, Doctor of Biological Sciences, Associate Professor
Stage Implementation Period: 01.04.2020 – 31.12.2022
Funding Volume: 1,422,300 UAH
The tested scheme of double-cropping potato culture as a measure to increase adaptability will be recommended for widespread use in production. Approaches were developed to enhance the adaptability of potato varieties and hybrids in expressing key agronomic traits. The quality and main biological characteristics of seed material of potato varieties recommended for cultivation have been improved. Using the obtained seed material significantly increased production efficiency by increasing yields while maintaining an optimal level of production costs.
Scientific level and novelty of the obtained scientific result: Given the absence in Ukraine and abroad of highly adaptable commercial varieties, which causes a significant product deficit in some years, the study first developed a methodology for assessing trait expression. It was developed during the experiment considering bottlenecks in its implementation and general biological patterns, primarily the expression of the trait in wild cultivated species that have evolved over a long time in variable external environments.
Practical significance of the obtained scientific result: Screening of commercial varieties was conducted based on adaptive potential. Different conditions were modeled, including the magnitude of factor effects. Trial diggings were performed, allowing the correlation of plant development phases with the pace of yield formation. To isolate the influence of each factor from their complex, meteorological monitoring (control) was conducted in all experiments at this stage during plant growth and development phases.
