The article details schemes of varietal certification of vegetable seed, set up criteria for establishing conformity of seed material moving in the international trade. Guidance has been adopted for field inspection of varieties of vegetable crops on control plots in the course of field inspection, post control and varietal laboratory control.

In this study, eight species of Chroogomphus are recognized from Europe: C. britannicus, C. aff. filiformis 1, C. fulmineus, C. cf. helveticus, C. mediterraneus, C. cf. purpurascens, C. rutilus, and C. subfulmineus. Different candidates for the application of the name C. rutilus are evaluated and the best fit to the description is selected; lecto- and epitypes are chosen to fix the name. Chroogomphus fulmineus and C. mediterraneus are also epitypified and a new species, C. subfulmineus, is described. The infrageneric classification is revised and a new subgenus Siccigomphus and three new sections, Confusi, Filiformes, and Fulminei are introduced. The former sections Chroogomphus and Floccigomphus are elevated to subgeneric level. Comparison of the ITS regions (nuc rDNA ITS1-5.8S-ITS2) of all species studied shows that there is a minimum interspecific difference of 1.5 %, with the exception of the two species belonging to sect. Fulminei which differ by a minimum of 0.9 %. Ecological specimen data indicate that species of Chroogomphus form basidiomes under members of Pinaceae, with a general preference for species of Pinus. Five European species have been recorded under Picea, while Abies and Larix have also been recorded as tree associates, although the detailed nutritional relationships of the genus, involving other suilloid fungi in particular, have yet to be fully clarified.

Assessment has been carried out for parental lines and hybrid combinations of forage beet by individual indices of productivity and morphological characteristics of root storages. Best combinations have been selected for further crossing and breeding.

The main reasons hindering expansion of assortment of horticultural crops and negatively affecting the provision of Ukraine’s population with horticultural production were discussed. The trend towards global unification of genotypes with parallel reduction of potential to andropoadaptability of chief horticultural crops is recognized as one of the main causes for instability in domestic horticulture crops production. Appropriate measures are proposed, including intensification of zonal specialization and intensification of the state protectionism over both domestic fruit farming and research developments, first of all in breeding and genetics, aimed at the ability to meet various requirements of producers, processors and consumers of fruits and berries to new cultivars.

The results of studying of walnuts collection have been given; the evaluation of the assortment according to resistance to unfavorable climatic conditions has been done; some varieties have been recommended for using in breeding and introduction in industry.

The article shows experimental data of interline hybrids of sugar beet on the basis of weight of 1000 seeds, genetic determination of characteristic based on the method of Hayman and topcrossed polytested crossbreeding is established, their comparison is made. It also highlights valuable hybrid combinations and valuable for combining pollinating lines used in the breeding to enhance properties of sowing seeds.
