Extension of agrobiodiverzity on the organic farming arable land thanks to using of genetic resources of spring wheat
 JANČÍKOVÁ, Lucie
This Thesis, focused on an evaluation of possible utilization of selected variety of wheat (Triticum aestivum L. and Triticum dicoccum Schrank) in organic farming in the light of possible expansion of agrobiodiverzity on an arable land, is connected with the Bachelor´s Thesis. The starting point of the process was a choice of twelve varieties based on previous screening. Small parcel of land experiments (2007 {--} 2008) with six genetic resources of emmer wheat and six varieties of sown wheat (4 old and land races, 2 modern check control varieties) have been grown on an experimental field of University of South Bohemian and Gene bank at Research Institute of Crop Production (VURV) Prague and subsequent evaluation of morphological, biological, economical and qualitative parameters as well. The results show, that genetic resources of wheat have lots of positive and negative features as well. A speed of growth, a height of plant or a tuft shape positively makes for an increment of a competition ability to weed. On the other hand, farming features e.g. a harvest index, a productivity of spike or a total yield is high variable by single kinds and compared to modern control varieties on a lowered level. Emmer wheat yields qualitative grain (high content of protein) in low imput farming. That is much better for other purposes than typical baker´s work (low swell of proteins expressed by Zeleny´s sedimentation analysis). This type of grown is suitable for organic farming and its growing currently contributes to expansion agrobiodiverzity on an arable land.

THE EVALUATION OF SELECTED OLD AND REFIONAL VARIETY OF SPRING WHEAT (TRITICUM AESTIVUM L. A STITICUM DICOCCUM SCHUEBL)
 JANČÍKOVÁ, Lucie
The Bachelor's Thesis deals with evaluation of selected morphological, biological and economical features of the old cultivars and land races complex. The purpose was to find the genotype with high content of protein in a grain and suggest the cultivars convenient for genetic resources {\clqq}on farm``. From the genetic resources of the Gene bank at Research Institute of Crop Production (VÚRV) Prague {--} Ruzyně was selected the assortment of 42 old cultivars and land races of wheat and 10 emmer wheat varieties (Triticum diccocum Schuebl) which are supposed to be rich in high content of protein in a grain. The evaluated complex was added by 10 modern cultivars as well. The fact that the protein content in land races of wheat is ordinarily higher than the protein content in modern breeded varieties has been confirmed. Therefore, the varieties mentioned above may achieve very goodquality production, even though on a lower yield level. It is appropriate for low-input farming, so-called organic farming.
