Abstract:

Foeniculum vulgare Mill. is a valuable essential oil plant, which raw materials and derived products, and, above all, essential oil, are widely used in the perfume and cosmetics, liquor, paint and varnish industries, in the food industry and medicine. The source material for cultivated plants selection, including F. vulgare, is the collections of the gene pool. The objective of this study was a comparative study of F. vulgare samples collection by the complex of features to clarify the possibility of identifying sources of economically valuable characteristics for creating promising breeding material. The study of the F. vulgare collection supported by the Research Institute of Agriculture of Crimea, which includes 75 samples rom 28 countries, was conducted in 2017–2019 at an experimental base located in the Crimea Foothills (Krymskaya Roza village, Belogorsky district). The collection samples were analyzed according to morphobiological parameters and productivity indicators. The work was guided by generally accepted methods, including those developed for essential oil plants. Statistical processing of the obtained data was carried out. The wide variability of the collection is shown, according to individual indicators (variation coefficients – from 8.3 to 54.4%). In this way, the mass fraction of essential oil (one of the most important indicators) varies within a wide range in the collection – from 1.09 to 3.86% (of absolutely dry mass) in whole plants and from 4.16 to 8.53% in fruits. The composition of the essential oil depends on the raw material. The anethole content reaches 80% in fruit oil, and the content of fenchone and terpene compounds is increased during the plant processing. The results of the collection analysis are basic, allowing preliminary sampling with high productivity indicators for inclusion in breeding studies.

Abstract:

The research of potato accessions preserved in Lithuanian potato gene bank genetic diversity research was carried out at the Voke branch of Lithuanian Institute of Agriculture in years 1990–2006. Research was provided with potato collection covering 200 varieties and hybrids from the main potato origin and growing regions and selection material bred in Lithuania. Potato varieties varied in accordance of morphologic, physiologic, immunologic and farming features in the different maturity groups and between groups. Using transgenic hybridization method and working with genetic material of local potato collection were selected potato varieties of Lithuanian origin. The key objective was to select the varieties immune to wart disease, cyst nematodes, with high resistance to other diseases, with excellent agronomic and cooking qualities, suitable for the processing industry. Over 1966–2006 years the collection of more than 350 flax breeding lines and varieties from different countries were investigated at the Upyte Research Station of the Lithuanian Institute of Agriculture. Therefore it is desirable for the new flax varieties to be highly adaptable, stabile yielding and high fiber quality under different growing conditions. The collection serves as a base while selecting flax varieties for hybridization. There have been chosen the varieties and breeding lines having the complex of qualities and positive characters. The varieties and breeding lines with positive characters were involved into the program of fiber flax breeding.
