Maintenance of potato varieties in <i>in vitro</i> and field collections of the Russian Potato Research Centre

The main biological feature of potato varieties is vegetative reproduction. This mode reproduction can be associated with problems due to the physiological ageing crop and accumulation specific pathogens causing reduced tuber yields. In order avoid these problems, seed production widely uses modern biotechnological methods. use meristemic technologies allows preserving identity biomaterial in process maintaining collection vitro , but even under conditions there a threat that modifications individual economically valuable traits may get fixed. varieties, such non-heritable deviations manifest themselves form shift phenophases period tubers ripening. high-tech methods varietal resources storage implemented on basis approaches, makes it possible maintain high quality biomaterial. At same time, mobility practicality remain criteria for effectiveness different methods, depending extent which they used practice. this review, at Russian Potato Research Center as an example considering stages formation functioning Bank Healthy Varieties (BHPV), supplies various regions Federation high-quality phytopathogen-free varieties.
