| Abstract:
Georgia is considered one of the primary centres of the origin of walnut. There are great prospects for its development. Walnut is characterized with high productivity in mountain areas of East and west Georgia on the elevation of 500-900 m from see level, as well as in high area of Ratcha-Lechkhumi and East Caucasus pre-mountain areas. Despite the significantly suitable natural and soil conditions for walnut growing in Georgia, demand on local market is more 4-8 thousand tons than the in-shell walnut production. That is why an amount of walnut is imported from other countries in high market prices. Therefore study and testing of the local germplasm, selection of high productive varieties and their extension in farms have great importance for filling this deficit. This article describes the materials of walnut germplasm study for Georgia. Prospective varieties and advanced selections are distinguished to each ecological zones of Georgia. Several walnut selections of lateral type and semi-dwarf growth are bread from Georgian walnut breeding program. The biological, agricultural and pomological description of selected varieties and new selections are also mentioned. The following varieties are recommended for production in various ecological zones of Georgia: Aragvi, Kaspura, Ackuri, Vanta, Goruli, Liakhvi, Ujarma, Manglisuri and Gareji. For breeding of lateral type varieties for target breeding purpose the following seedlings are recommended: No 2, No 3, and No 5. | |
