Abstract

Skin scuffing is a problem of washing of the individual potato varieties, which is particularly important at harvests of physiologically immature tubers. Washing of such tubers cannot be recommended. Discoloration of scuffed tuber parts is another problem, which is exhibited by gray, brown to black color. Greening of washed tubers is mostly influenced by storage manner that also affects tuber sprouting. Mechanical damage, occurrence of several diseases, abiotic injuries, pest damages is also a problem. Various responses of potato varieties were found to tuber washing. Varieties with rough, netted skin, physiologically immature tubers, infected with diseases, mechanically damaged, susceptible to soft rot, expressing abiotic changes are not suitable for the washing. Tubers of varieties with smooth and bright skin, without scuffing, with later greening in the light, free of disease and abiotic injury presence and non-damaged by pests are suitable for washing. From this view the best results of tuber washing were obtained with varieties and hybrids: Adéla,Astoria, Belladonna, Dali, Ditta, Flavia, Futura, Katka, Kordoba, Kornelie, Lady Christl, Laura, Milva, Princess, Redstar, Rosara, Samantana, Satina, Secura, Velox,Vera,Victoria, KE 524-11, KE 12-83.
