The purpose of the article is to explore existing views on methodological approaches to the valuation of non-material assets through a prism of the development of intellectual property and capitalization of agricultural enterprises in modern conditions. Research methods. Dialectical method of scientific cognition, analysis and synthesis, systematic generalization (generalization of approaches to the valuation of non-material assets and drawing conclusions), methods of abstraction, comparison (when estimating the initial and fair value of a plant variety) were used in the research process. Research results. Approaches to the valuation of non-material assets through a prism of the development of intellectual property and capitalization of agricultural enterprises were considered and generalized. The method of estimating value of plant variety was substantiated; the proposed method of determining an initial and fair value of a plant variety was based on the rating of each object. Elements of scientific novelty. Based on the generalization of approaches to valuation of non-material assets, a method for estimating value of a plant variety based on establishing the rating of variety, its volume and term of use, and agreed percentage of royalties was proposed. Practical significance. Conclusions, suggestions and practical recommendations, as well as the proposed methodology for estimating value of a plant variety, when applied in practice, can significantly change the relationship between plant selection breeders, seed variety owners and seed producers, and provide fair financial calculations, which would give a new impetus for the development of national selection.
