Grain quality of the pseudocereals buckwheat (Fagopyrum esculentum Moench), quinoa (Chenopodium quinoa Willd.) and amaranth (Amaranthus hypochondriacus L. x A-hybridus L.) in relation to growing conditions

An introductory survey summarizes traditional and actual products made of b uckwheat, quinoa and amaranth grains. Additionally a table about the range of grain ingredients is briefly discussed. The following investigations wer e designed, to answer the question: how far do temperate climatic condition s allow, to produce marketable grain yields! Grain yields harvested in a tw o years field experiment were analyzed concerning external quality traits ( 1000 grain weights, sieve fractions and grain colours) and internal quality traits (ingredients, fatty acids). The factorial field experiments include d varieties of each species and sowing densities combined with N-rates. Besides general differences between the varieties quality traits were more affected by the years as related to the production measures. Not all traits reached the expected levels completely. Especially sieve fractions and gra in colours should be improved. In consideration of these deficiencies marke table grain yields can be produced even under temperate climatic conditions , further research provided. Predominantly investigations should include th e effects of fungal diseases of the inflorescences on grain quality traits.
