The aim of our research was to evaluate the genetic diversity among 25 commercial varieties registered in Poland and 14 landraces of Phaseolus vulgaris var. nanus Asch. (the dwarf common bean) and Phaseolus coccineus L. (the runner bean) maintained in the National Centre of Plant Genetic Resources in Radzików. An additional goal of this study was to compare(More)
In Poland oat breeding began at the late nineteenth century. During the World War II almost all of Polish breeding materials were lost, and then were replaced by German cultivars. The main aim of this paper was to show the level of genetic diversity of Polish oat cultivars which were bred before 1939. Simultaneously usefulness and informativeness of(More)
The paper presents a diversity study of eight Avena strigosa landraces originating from different parts of the world. The analysis was based on morphological description, isoenzymes and inter simple sequence repeats. Uniquely, the variability within each tested accession at the DNA level was identified. The isoenzymes analysis was not sufficiently sensitive(More)
The aim of the presented research was to settle conditions and parameters of Pleurotus ostreatus (Fr.) Kumm. culture and to determine activity and yield of cellulase complexes biosynthesised by this mushroom on different substrates. Wheat straw sterilized by evaporation at temperature 58-60 degrees C during 48 hours was the first substrate. Wheat straw with(More)
Here we focused on Polish oat landraces developed in the moderate temperature zone attempting to understand their genetic and phenotypic variability in context of the pressure of environmental constrains at the locations where they had evolved. Besides molecular markers and diverse phenotypic traits the Fourier transform infrared (FTIR) spectroscopy,(More)
