Description
Summary:Experience shows that yield potential in organic farming varies much more widely than in conventional agriculture. [...]expectations for organic varieties include higher adaptability and plasticity, combined with consistently high quality. New varieties for organic production must have a greater resistance to abiotic and biotic stress conditions, more efficient uptake of mineral nutrients and better exploit of the existing environmental conditions. Since the problems of weeds in organic crop production are more pronounced if it's the initial criteria, it is certain that varieties incurred by this means should be selected, based on the other grounds (Berenji, 2009). The aim of this paper was to study phenotypic variability for yield components in spelt genotypes which can be used as parent cultivars in organic plant breeding programs for improvement of grain yield and quality of spelt wheat. According to the results, number of grains per spike depended significantly on genotype and genotype x year interaction.
