Technological Characteristics Comparative Study of Pamid Variety Clones

Comparative study of the technological characteristics of the newly-selected clone 5/76 of Pamid variety and clone Pamid Ruse 1, grown in the soil and climatic conditions of Pleven (Central Northern Bulgaria) was carried out. The study included three consecutive vintages . It was found that Pamid clone 5/76 greatly surpassed the productivity and grapes quality of the control - Pamid Ruse 1. The mechanical analysis did not reveal any significant differences in the cluster and berry structure and composition of the investigated clones, as well as in their theoretical yield. Pamid clone 5/76 showed better sugar accumulation capacity. There were no significant differences in the acidity content of the grapes of the two clones. The wines produced from the newly-selected clone Pamid 5/76 had higher alcohol, sugar-free extract, total phenolic compounds and anthocyanins content compared to the control samples from Pamid Ruse 1. In the organoleptic analysis the samples from Pamid 5/76 were assessed the highest. These variants had more intense, vivid color, the soft, elegant tannins dominated in their taste
