Abstract

Aim. Evaluation of starting material on a complex of economically valuable features and creation with its participation of a variety-synthetics of alfalfa sowing. Methods. Field, laboratory. Results. The results of research and creation of a synthetic variety of alfalfa of sowing Radoslav at the Institute of forages and agriculture of Podillya of NAAS are presented. Listed on the State Register of Plant Varieties Eligible for Distribution in Ukraine (hereinafter – the Register of Plant Varieties of Ukraine) (Certificate of State Registration No. 15196001 of March 14, 2019, Patent for the Plant Variety of Radoslaw No. 190654 of May 5, 2019). When evaluating fodder and seed productivity in the research fields of the institute, the preference for the Radoslav variety to the Sinyukh standard was established. Extensive testing of the suitability of the variety for propagation (SPD) in 5 research points of the Polesia zone and 4 ˗ of the Forest-Steppe Institute of Plant Variety Examination confirmed higher rates of fodder and seed productivity and growth rate of the specified variety compared to the conventional standard. Conclusions. In order to enhance the efficiency of the breeding process aimed at the creation of synthetic varieties, clonal genotypes should be used, which, along with the complex of economically valuable traits, are distinguished by a high overall combining ability. It is recommended to use synthetic alfalfa of sowing Radoslaw in clean and mixed crops with other perennial herbs for production of high-quality forages in the soil-climatic zones of Polissya and Forest-steppe.

Keywords: Medicago sativa L., clone, synthetic variety, dry matter, seeds.
