Productive and adaptive potentials of Renet Simirenko variety on rootstocks with different growth rates in arid conditions

This article presents the results of economic and biological assessment Renet Simirenko variety grown on rootstocks different growth rates under conditions insufficient moisture high thermal stress in arid zone Northern Caspian region. The purpose research is to study identify scion-rootstock combinations variety, which most fully realize potential productivity, early maturity, resistance unfavorable environmental factors. Studied grew more intensively dwarf (SK4, SK7), semi-dwarf (SK2, SK5), average height 54-118, restrained tree-holes was provided by SK3, P16, P59, P60. In rootstocks, flowering began year planting, fruiting - second garden growth, indicates maturity. Rootstocks SK4, SK2, 54-118 maximum total yield marketable comparison with control for 7 years. Astrakhan region, it advisable grow low-growing resistant destabilizing factors climate providing regularity.
