The analytical researches of sea buckthorn 3 cultivar ad 11 hybrid forms showed that it was cv Oliana that had the larg-est fruit mass (0,7). The berries of the variety Osoblyva and hybrid 1-15-3 had the maximum part of non-soluble organic substances (at a levil of 24.7 and 25.6 % respecti vely). The largest amount of dry soluble substances (13.1 %) during the growth and development period was accumulated by the fruits of the hydrid forms 1-15-8c and 1-15-2a and 1-15-2. The berries of the cultivars Osoblyva and Adaptyvna contained the largest (6.2 and 5.8 % respectively) number of sugar while those of most of studied forms had 3.0 %. The organic acid content in the ‘Oliana’ fruits was 2.77 %. That is less than the hybrids by 1.53 %. The pectins amount in the berries did not exceed 0.51 % of the total number and 0.44 % of the pro-topectine content/ The ascorbic acid maximum (over 15 mg/100 g) was accumulated by the fruits of the variety Adaptyvna and hybrid 1-5-30 and 1-5-15, The mentioned cultivar included the largest polyphenols amount (379 mg/100 g). According to the organoleptic physical and biochemical indicators the ‘Oliana’ fruits were recognized the most favoura-ble for freezing and storage in the frozen state among the studied cvs.
