Ampelographic Characteristics of New Grape Varieties
Abstract
This article is devoted to the ampelographic evaluation of newly developed grape varieties, namely Nakhchivan Muscat, Nargizi, and Alinja. The study investigates their ecological, phenological, agrobiological, and biomorphological characteristics, examines their genetic structure, and provides a comprehensive description based on standard ampelographic descriptors.
The Nakhchivan Muscat variety was selected from plants obtained in 1985 through the treatment of germinating seeds of the Uzbek Muscat variety with a 0.3% colchicine solution for 24 hours. The plants selected from the resulting seedlings were chosen for further cultivation. The newly developed variety was granted a patent and copyright certificate in 2020 (No. 00288; author: Professor V.M. Guliyev). The average yield per vine is 11–13 kg.
The Nargizi variety was developed in 1980 via open pollination of seeds of the Uzbek Muscat variety. Seed germination was stimulated using a 0.3% colchicine solution for 48 hours, followed by the selection of promising genotypes from the resulting seedlings. The variety was granted a patent and copyright certificate in 2020 (No. 00291; author: Professor V.M. Guliyev). The average yield per vine is 15–17 kg.
The Alinja grape variety was developed through open pollination of the Meleyi variety. Prior to germination, the seeds were treated with a 0.5% colchicine solution for 48 hours. For cultivation subsequent selection was carried out among seedlings. The Alinja variety was granted a patent and copyright certificate (No. 00284; author: Professor V.M. Guliyev). The average yield per vine is 10–12 kg.
The article presents a concise ampelographic characterization of these newly developed varieties.
