Fruit growing
and viticulture of South Russia

Annotation

It is given the integrated assessment under the conditions of Northern Ossetia-Alania of the main agric and biological characteristics and economic efficiency of new apple-tree varieties, immune and steady against a scab, the most from which are created in NCRRIH&V together with State Scientific Institution All-Russian Research Institute of Horticultural Breeding. The research were carried out according to the standard programs and techniques of breeding and variety's studing. The most fast maturing apple-tree varieties of Feya and Talisman which started the fructification for 1-2 year after landing are selected. The high productivity is noted for Carmen, Rassvet, Talisman, Vasilisa and Granatovoe (31,0-38,5 t/hectare). The high yield of standard fruits (to 80-85%) is noted for Feya, Carmen, Orpheus and Granatovoe. The indicators of economic efficiency of cultivation of new varieties are calculated. The most perspective apple varieties for industrial cultivation are selected: Rassvet, Carmen, Granatovoe. High level of economic efficiency of cultivation of these varieties are caused by an optimal combination of immunity to a scab with a complex of the main economic signs: fast and high productivity, fructification regularity, high quality and standardization of fruits. The highest growth of profitability is noted in a group of autumn apple-tree varieties - to 16,6% (Carmen), and in a group of winter varieties - to 24,8% (Granatovoe). In a group of early summer varieties the Rassvet variety on profitability level corresponds to a control variety of Geneva Erli, wich is the one of the best variety of this maturing term. The use for optimization of industrial assortment in the Northern Ossetia-Alania of new apple-tree varieties, immune and steady against a scab, will allow us to increase in economic efficiency of gardening branch and to improve an ecological situation in the region due to decrease in number of processings by means of plantings chemical protection.
