ECONOMIC EFFICIENCY OF CULTIVATION OF APPLE TREES ON DIFFERENT TYPES OF CLONAL ROOTSTOCKS IN THE CONDITIONS OF THE MIDDLE VOLGA REGION ^{[№ 4 ' 2017]}
Low-growing fruit trees on weak-growing clonal rootstocks are best suited to the requirements of intensive gardening. Vegetatively produced clonal rootstocks of apple created by V.I. Budagovsky, S.N. Stepanov, A. Veytenberg, O.K. Dyadchenko, P.K. Shuvalov allowed to grow trees with early appearance of fruit, with the limited dimensions and high productivity in Central Russia, the Volga region and the Urals. The experiment was done on middle-growth dwarf trees and high-growth trees the conditions of the Middle Volga, in Samara. The most productive trees were grown on middle-growth rootstock. Harvest exceeded by 51.8 % of the trees on the high-growth rootstock and by 17.3 % on dwarfs ones. The cost price on middle-growth rootstock was 8.9 rubles, on dwarf 12.0 rubles, in control 10.1 rubles. The highest profitability of 27.3 % was in the option for middle-growth rootstocks, which is 2.5 times higher than in the control sample. In conditions of insufficient moisture in the Middle Volga most profitable crops were on middle-growth rootstock 57-233.

FRUITFUL TREES OF AN APPLE-TREE ON DWARFISH STOCKS ON AVERAGE THE VOLGA REGION ^{[№ 3 ' 2016]}
In materials of the publication results of studying of a condition of skilled plantings of an apple-tree of a bookmark of 1985–1986 in the conditions of Central Volga area are presented. Apple-tree grades Spartak and Antonovka on various vegetative made multiple copies stocks were objects of research. Results of supervision cover time period from 1985 to 2015. The assessment of survival of saplings in an orchard and states in 2015 is carried out. Safety of plantings in 2015 was the greatest on a grade Spartak on Paradizke Budagovsky, 62-397, SPS-7, 60-165, a hybrid No. 1, 18-7, 4-1 (Ural-1). On Antonovk's grade ordinary — on 18-7, 4-5, 18-8, 19-3, 4-7. Grade trees Spartak on stocks 3-17-38, 62-396 — 3,8–4,3 m, Antonovk's grades — on 62-396 — 3,8m were the highest. The good harvest of fruits was received in 2013 and 2014. In general for years of supervision the most big crop made on a grade Spartak on stocks of SPS-7 and the Urals-1 (4-1) 2264–1496 c/hectare, is slightly 62-397, 60-165, 18-7, 18-6 less that in relation to control makes 198–248 %. On Antonovk's grade ordinary in group high-yielding the sorto-podvoynykh of combinations it is possible to carry stocks 4-7, 18-8 which productivity by 2–2,5 times exceeds control. The least fruitful were on a grade Spartak on Paradizke Budagovsky, 4-5, and on Antonovk's grade ordinary — 18-6. Thus the forms which remained in a productive state to 30-year age are distinguished from dwarfish stocks.

THE BEST CLONAL APPLE-TREE ROOTSTOCKS OF THE VOLGA-URAL REGION ^{[№ 1 ' 2015]}
The paper summarizes more than 30 years of research on the vegetative apple rootstocks that have been bred in the breed shed, the nursery, and in the garden in the Middle Volga and Southern Urals regions. The final evaluation of rootstock variety combinations has been given in the garden of the Middle Volga. The best form were half-dwarf rootstocks 64-143, Ural-5.
