Abstract

The paper presents the results of the study (2016–2020) of five grapevine varieties under the code name Bessergenevsky at the Don ampelographic collection named after Ya.I. Potapenko (Novocherkassk, Rostov re-gion). In 1949, when examining the varietal composition of old grapevine plantations (in the village of Bessergenevskaya Rostov re-gion), grapevine varieties were discovered and called Bessergenevskie. Among them, some varieties turned out to be promising. As con-trols, we used classic varieties – for white ber-ry – Riesling Reinskiy, for varieties with col-ored berries – Cabernet Sauvignon. The per-centage of blossoming eyes in most of the studied varieties was higher than in the control ones (except for varieties – Bessergenevsky No. 7 and Bessergenevsky No. 3). The per-centage of fruiting shoots and the coefficient of fruiting in all studied varieties were lower than in the control ones. The average bunch weight varied from 84 g in the control variety Risling Reinskiy to 346 g in the Bessergenev-sky variety No. 7. In terms of yield (as well as the average bunch weight), all varieties (except for Bessergenevsky No. 5) exceeded the con-trol ones. For a more complete characterization of the studied varieties, auvological assess-ment was made. Samples of wine materials were prepared from the studied varieties ac-cording to the classical technologies for the preparation of white and red table dry wines. The highest degustation marks (8.8 points) were obtained for the control varieties; from the studied varieties, a sample – Bessergenev-sky No. 10, was pointed out, which received an estimate of 8.6 points. On the basis of the research among five grape varieties according to a complex of economically valuable traits, a medium-late wine white-berry variety Bes-sergenevsky No. 10 was distinguished, from which good quality dry table wines of a pale straw color, with a delicate harmonious aroma of field herbs and light floral tones are ob-tained.
