The standard for seeds of Diplotaxis tenuifolia L. was developed. It includes the following sections: scope of use; normative references; terms, definitions and abbreviations; classification; technical requirements; acceptance rules and sampling; method of control; transportation and storage; safety requirements.

Purple horsemint (Monarda citriodora L.) is a perennial plant belonging to Lamiaceae family and being cultivated as aromatic and ornamental crop in many countries of Europe and America. Last years this plant actively gains popularity among gardeners. To elaborate the standard of organization with title 'Seeds of Monarda citriodora L. Sowing qualities. Technical conditions' the basis data has been collected from laboratory of leafy, aromatic, scented and ornamental plant breeding, laboratory of stardatization, rationing and metrology at VNIISSOK. The standard for seeds of Monarda citriodora L.includes the following sections: field of utilization; normative references; terms, definition, abbreviation, classification; technical requirements; order for receiving and sample piking;method of control; transportation and storage; security requirements.

The data of spring-summer sowing time of vegetable root crops of the family Brassicaceae in the open filed are presented. Five varieties and three hybrids of daikon, seven varieties of radish, and four varieties of turnip were tested. Based on the results, the minimal and maximal root weight for each time of sowing were determined; average fresh weight of vegetable roots for three years of investigation was accounted.

The results of winter and spring sowing times of vegetable root crops of Brassicaceae family in protected area are presented. Five varieties and three hybrids of daikon, seven varieties of radish, and five varieties of turnip were studied. The minimal and maximal weight of roots for each sowing time was revealed. The average weight of products over three years of research was calculated.

Relevance. One of the most important directions in the breeding and variety study of fruits, in particular domestic plum European, is the breeding of cultivars with high commercial and consumer qualities of fruits. In this regard, the assessment of some commercial and consumer qualities of fruits in plum cultivars of the RRIFCB gene pool was of great practical and scientific interest. Material and methods. As objects of research, we used 8 plum cultivars of the RRIFCB gene pool and a control cultivar of the RRIFCB breeding Bolkhovchanka. The studies were carried out on the basis of the laboratory of breeding and variety study of stone fruit crops of RRIFCB in 2015-2019. Determination of color, shape, average weight, taste, size of fruit, size and shape of the stone, density of pulp, separation and length of the stalk, color of the juice were carried out in accordance with the "Program and methodology for the variety study of stone fruit crops" and "Pomology". Results. Most of the studied plum cultivars from the gene pool of the Russian Research Institute for Fruit Crops Breeding have valuable commercial and consumer qualities of fruits, which will allow them to be used in further breeding for this trait. Cultivars Californiyskaya krupnaya, Zarechnaya rannyaya, Volgogradskaya can be recommended for further use in breeding as sources of high fruit mass. Cultivars Californiyskaya krupnaya and Bolkhovchanka can be recommended for further use in breeding as sources of high pulp content in fruits and fruit sizes. On the basis of the tasting assessment of the fresh fruits, the fruits of the cultivar Volgogradskaya stood out positively.
