Central Asian Research Station of VIR

History and Development

The Central Asian Research Station of the All-Union Institute of Plant Industry (now the Central Asian Branch of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources — VIR) is a research institution that played a key role in collecting and preserving the grapevine germplasm of the Asian region. The station was founded in 1924 near Tashkent, Uzbekistan, on the initiative of Academician N.I. Vavilov. The location was chosen due to the specific nature of the region, which stands as one of the ancient centers of origin for cultivated table grapes.

For decades, the institution's primary task was the mobilization of global and local plant genetic resources. Through numerous expeditions, station scientists assembled and systematized a unique ampelographical collection containing over 1,600 grapevine accessions. This repository served as the foundation for studying the biological traits of indigenous Central Asian varieties and utilizing them in breeding programs across the USSR and internationally.

Core Scientific Activities

The station's activities were focused on the following areas:

• Germplasm Study and Conservation: Systematizing ancient indigenous varieties of Central Asia and Kazakhstan, including evaluating their drought and salt tolerance.
• Breeding of Table and Seedless Varieties: Developing new large-berried table grape varieties adapted to the harsh conditions of a sharply continental climate with hot summers.
• Clonal Selection: Identifying and propagating the most productive variations and mutations within traditional Asian grape cultivars (such as Husayne, Tayfi, and Nimrang).
• Identification of Breeding Donors: Discovering and establishing valuable agricultural traits (large berry size, firm flesh texture, seedlessness) to pass into promising hybrid lineages.

Breeding Results and Created Varieties

The station's work was strictly oriented toward table viticulture to produce high-yielding forms with exceptional shipping potential.

Celebrated grape varieties bred by the Central Asian Station of VIR include:

Table Grape Varieties:

• Rannii VIRa: An early-ripening table grape variety obtained from a cross of Eastern cultivars Chaush × Kishmish Chernyi. It features large, round berries and a balanced flavor, and is widely grown across Uzbekistan.
• Pozdnii VIRa: A large-berried table grape variety of late-season maturity (late September to early October), obtained from a cross of Nimrang × Dodrelyabi. It possesses large conical clusters and round black berries with firm, crisp flesh, characterized by high yields and excellent transportability.
• VIR-1 (Breeding Donor): A specialized teinturier (red-fleshed) wine grape variety selected from self-pollinated seedlings of the French cultivar Petit Bouschet. It features intensely colored juice and high yields, and was widely utilized by other breeding centers as a genetic donor for deep color.

Currently, the Central Asian Branch of VIR maintains its status as a historic repository of grapevine genetic resources in Central Asia.
