Abstract:

Because of its beneficial nutrients, particularly its protein content and suitability for a gluten-free diet, Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.), a pseudo- cereal, is gaining great attention. The objective of this thesis was to evaluate the yield, morphological traits, and nutrition component from selected genotypes of Tartary buckwheat under the climatic condition of the Czech Republic. Morphological traits of the samples in 2022, including plant height, branching, inflorescence characteristics, yields, etc., were evaluated, while the data from 2019 – 2021 were provided by the Crop Research Institute (CRI) to compare them with the results obtained in 2022. The nutrition components of the samples in 2019 – 2022, including protein content, total phenolic content, and antioxidant activity were analyzed. The morphological traits of samples from different origins did not show significant differences. Although the yield and weight of thousand seeds (WTS) were less in 2022 compared to the previous years, the average protein content, total phenolic content, and antioxidant activity were 11.30% of dw, 144.58 mgGAE/gdw, and 39.76 μmolTE/gdw, respectively. The total phenolic content, antioxidant activity, and protein content of each production year (from 2019 – 2021) were significantly different, while the results from samples belonging to each origin were not different. Some genotypes showed great potential. The genotype from Slovenia represented the highest yield under unflavored weather conditions, whereas the American genotypes showed a high number of seeds per cymes. Hence, these were proposed for further investigation into improving the Tartary buckwheat for the conditions in the Czech Republic.
