In 2021, the breeders of the NSC "IVIV them. V. E. Tairova" began to study a group of introduced and own selection of varieties and forms of different genetic and geographical origin.

This is stated in an AgroTimes column by the institute's employee Lyudmila Gerus.

“The purpose of our work was to study the adaptive potential and compare its level in the group of introduced varieties and varieties of our own selection.” she writes.

The level of adaptive traits depends on the mechanisms of protection against abiotic and biotic stressors, which are justified by the origin from resistant varieties.

For example, the origin from frost-resistant varieties of Vitis amurensis substantiates the presence of anatomical and biochemical mechanisms of protection against exposure to negative temperatures, and the presence of genes of resistant American species in the calculated genetic formula determines biochemical and physiological features that provide a high level of resistance against pathogens of diseases of fungal etiology. Also, the origin from drought-resistant Central Asian varieties helps to reduce susceptibility to the influence of lack of moisture supply.
