The table value of tubers from organic and conventional potato growing system
BOUŠKOVÁ, Michaela
The objective of this thesis was to assess the potato varieties produced by ecological and conventional farming, to find out the deviations of cooking types and to establish the cooking quality of the tubers The cooking quality of potatoes was established subjectively, based on sensory analysis. The individual characteristics of the cooking quality which were assessed included the colour of flesh, consistency, texture, flouriness, moisture, taste, and tuber darkening after cooking. The results suggest that the characteristics of the cooking quality depend mostly on the variety. The year of growth and the ways of farming also form a minor influence. The deviations of the actual cooking type of the assessed varieties from the declared cooking type were established according to the method of the Czech Agriculture and Food Inspection Authority. The results of the assessed varieties show that the cooking type was not affected; minor differences were caused by the year of growth.

Evaluation of tuber cooking quality in selected table potato cultivars cultivated under organic and conventional crop management
ŠPLÍCHALOVÁ, Veronika
The aim of this diploma thesis was to evaluate the effects of conventional and organic crop management on cooking quality of potatoes. In one-year potato field trials (year 2010) with different crop management (conventional versus organic), 13 table potato genotypes (Adéla, Bionta, Karin, KE 100/10, Laura, Madona, Magda, Princess, Red Anna, Rosara, Solara, Satina,Terka) were used. The cooking quality (i.e. colour of the flesh, consistency, mealiness, moistness, flavor and darkening) was subjectively assessed using sensory analysis according to VORAL (1996) method. Only structure of boiled potato tubers was significantly affected by different crop management (4.8 % from total variability). Genotypically declared cooking types in used potato genotypes were confirmed in both production systems.
