Evaluation of common quince of VNIISPK breeding as pear seedling rootstock for fruit production in Central Russia

Abstract

The article presents preliminary results of studies on the assessment of VNIISPK breeding common quince use as an intensive type seedling rootstock for pear cultivation in the conditions of Central Russia. It was established that the common quince of VNIISPK breeding is suitable to be used as seedling rootstock of pear in conditions of the Russian midland and has sufficient winter resistance of overground and root systems, high seedling yield in seedling rootstock breeding and good compatibility with some pear varieties. Strong fusion with the rootstock and active growth development when using an apple-pear hybrid No. 818 was noted; it can be recommended as an intermediate stock (mediator) in incompatible variety-rootstock combinations. Research in this direction will be continued.

The results of the evaluation of the compatibility of pear cultivars with dwarf rootstocks of VNIISPK breeding for intensive fruit production technologies in Central Russia

“…На сегодняшний день учеными ВНИИСПК получены отборные зи-мостойкие формы, способные переносить климат средней полосы России. Установлено, что корни отдельных сеянцев айвы обыкновенной селекции ВНИИСПК могут без повреждений переносить понижение температуры почвы до минус 11-12 °С [4][5][6]. Примерно такие же показатели характерны и для корневой системы грушевых подвоев.…”
