Abstract

The article describes the differentiation of collection samples of marigold at Experimental station of medicinal plants using cluster analysis as to sixteen components of the group of flavonoids, highlighted with high performance liquid chromatogram. The selected six clusters, which are characterized by the complex of economically valuable sings: plant height, diameter of the bush, productivity of plants by dry inflorescences and seeds, weight of 1000 seeds, vegetation period and the content of total flavonoids. We developed and presented numerical score for each of these sings of the six clusters. According to the results of the integrated valuation we found the highest amount of points at the samples of cluster 5, which was 35 points. The selected varieties of marigold of the fifth cluster such as Radio, Berezotits’ka sonyachna, Oranzhevyy blysk, and a sample Co-12-115 were found to be promising for future use in the selection process.
