Micropropagated Plants

The reaction of 10 commercial potato cultivars to infection by Spongospora subterranea was evaluated in the field and in the greenhouse. Micropropagated plants were used in the greenhouse and seed pieces were used in the field. The relative susceptibilities of the cultivars when measured in the greenhouse and in the field were comparable. The overall severity of scab on tubers was 8 times higher in the greenhouse than the field. The relative susceptibilities of 3 standard cultivars (Kennebec, Katahdin and Russet Burbank) were consistent over 3 greenhouse trials. When comparing planting material in the greenhouse, the incidence and severity of scab on the progeny of micropropagated plants did not, in general, differ significantly from that on the progeny of seed potatoes. Furthermore, the incidence and severity of scab on tubers of the highly susceptible cv. Kennebec grown in the greenhouse were not affected significantly by type of potting mix (well-drained, compared with poorly drained which inhibited plant growth). Screening potato cultivars for resistance to powdery scab on a small scale in the greenhouse, using micropropagated plants, is suggested as a preliminary to the evaluation of cultivars in the field.

The aim of this article is to assess the competitiveness of domestic and foreign potato cultivars grown in the country and to analyze the use of certified seed potatoes by the producers. The agronomic and utility value indicators were adopted as the measure of competitiveness of varieties. It has been shown that table cultivars of polish breeding in relation to foreign cultivars have generally higher agrotechnical value and higher yields but at the same time in many characteristics they have lower utility value (for example the look of tubers). The rate of use of certified seed potatoes depends on the degree of marketability of particular potato production sectors. It ranges from just 6.4% in multidirectional production to 25% in table and starch potato production, up to 40% in the production of early table potatoes and for food processing.

Economically Valuable Traits

В 2016–2017 годах в коллекционном питомнике изучали 170 образцов картофеля мировой коллекции ВИР и других НИУ с целью выделения источников ценных признаков. По комплексу хозяйственно ценных признаков выделилось 7 сортов. Сорта и гибриды, выделившиеся по отдельным признакам и комплексу признаков, используют в селекционной работе как исходный материал для создания новых сортов картофеля.In 2016–2017 years the collection nursery studied 170 samples of potatoes of world collection of VIR and other research enterprises to select sources of valuable traits. The complex of economically valuable traits stood out 7 cultivars. Cultivars and hybrids released for individual signs and the complex signs used in breeding as source material for creating new potato cultivars.
