The results of evaluation of yield capacity and resistance of sweet cherry varieties on clonal rootstock VSL-2 to stress abiotic and biotic factors are presented. The most effective variety-rootstocks combinations are selected.
The results of research of varieties of apple pollinators (krebs and ranets) on their stability to abiotic and biotic factors are presented. Fast fertility and yield of varieties-pollinators are studied. The most stable and fast fertile varieties and hybrids are allocated
The results of long-term economy-biological evaluation of pears varieties on rootstock VA-29 in the conditions of Stavropol region are presented. On the total combination of valuable traits the pears variety-rootstock combinations of different maturing are recommended.
The evaluation of growth, development and yield capacity of apple pollinators is given. As a result of comparison of periods of blooming some groups of apple pollinators are offered.
The main rootstocks of sweet cherry under conditions of Stavropol Region are seedlings of Antipka. The lacks of this stock are the intense growth and the late introduction in the fructification (for 5-7 year). At the Crymsk Experimental Breeding Station the VSL-2 rootstock is removed which is recommended for middle and southern areas of fruit growing of Russia. This rootstock provides a low growing of trees and the introduction of sweet cherry in fructification for 2-3 year after landing. The work purpose is to estimate the efficiency of use of VSL-2 rootstock for sweet cherry varieties at different methods of grafting under agriecological conditions of Stavropol Region. The work is carrying out by use of programs and techniques of varieties studying of fruit, berry and nut cultures. According to researches of 2008-2013, the Donetsk Ugoliyk sweet cherry on VSL rootstock was allocated on productivity (to 31 kg / from one tree) and on the weight of fruits (9 g). On the ninth year of vegetation the productivity of Donetsk Ugoliyk variety at an early-spring inoculation by 10-15 cm shoot exceeded control (productivity of 6,1 kg / from one tree that is on 9% higher than control). By data for 2005-2009, a tendency to low growing of Donetsk Ugoliyk variety is noted at a summer inoculation on the height of 45 cm. The tendency to intensive growing is noted in control and at an early-spring grafting by shoots of 50-55 cm long. On size of realization profit the Donetsk Ugoliyk and Yaroslavna were allocated from studied varieties of sweet cherry.
