Comparison of Selected Traits of Common and Tartary Buckwheat Originated from China and Czech Republic under Conditions of the Czech Republic

摘要

A set of common and tartary buckwheat accessions originated in China and Czech Republic was evaluated in the framework of joint project "Diversity of buckwheat (Fagopyrum sp.) genetic resources and its use in suitable agriculture and healthy food production in the Czech Republic and China". The experiment was launched in Prague locality on 2.25 m2 plots in four replications. Selected morphological characters were described in detail.Weak branching was observed in '(S)pa(c)insk?1' only. White colour of flowers was characteristic for common buckwheat whereas greenish-yellow for tartary buckwheat evaluated accessions. Flowering started earlier in the most of common buckwheat accessions. On the other hand maturity started earlier in tartary buckwheat. Consequently, the period from flowering to maturity was shorter in tartary buckwheat accessions. High WTS was identified in common buckwheat cultivars ('Jana' and 'Kara-Dag') registered in the Czech Republic and in Chinese 'YU' and 'Dali' as well. Crude protein content was higher in common buckwheat when compare it with tartary buckwheat.
