| The methodology takes the different ideotype of plant that´s suitable for the environment-friendly farming systems into account. The methodology is being tested at several varieties and species of genus Triticum L. (wheat ? winter wheat, spring wheat, landraces, conventional varieties and the varieties recommended for organic farming system, emmer wheat). The methodology is dividend into four part: morphological, biological, economic and quality characters. |

| Organic farming is perceived as a system with a number of positive impacts on all components of the environment. For more precise assessment of differences in environmental impacts of conventional and organic farming, we need to be able to measure and quantify such impacts. For this the LCA (Life Cycle Assessment) method may be used as a tool. Among other, the LCA method is also an invaluable tool for assessing GHG emissions related to agricultural production. In this paper, the use of LCA for evaluation of GHG emissions from Zea Mays L. growing is presented. The emission load was calculated by the simplified method LCA, impact category: climate change. The calculation was performed by SIMA Pro software with integrated ReCiPe Midpoint (H) method. The... |

| The contemporary state of farming has been evaluated and organic and conventional farming systems have been compared in the framework of the analysis of structure of farming in the Czech republic. The selective group of 437 associations, consisted of 3 subgroups, is divided into several categories according to the farming method and altitude. Parametres of plant and animal production and use of the agroenvironmental programmes and measures are evaluated. The evaluation of the structure of farming permits to find optimal possibilities of future development of conventional and organic farming in the Czech republic and of arrangements of the settings of grants and subsidies. |

| Organic farmers are interested in the growing of spring spelt wheat forms (Triticum spelta L.). Therefore, the important agronomical characteristics and baking quality of six spring spelt wheat landraces were studied and evaluated. The studied and evaluated cultivars were inclined to lodging and wheat diseases. Their yield rate is determined by the length of the spike and the weight of one thousand grains. The grain yield and the crude protein yield per hectare achieved the same level in organic farming. The spring spelt wheat forms stand out in high protein content and wet gluten content; the gluten was, nevertheless, weaker and less swollen. |

| Odborná monografie se zabývá problematikou posklizňové úpravy, skladování a zpracování rostlinných produktů v ekologickém zemědělství. Nejprve popisuje požadavky a postup při posklizňové úpravě produktů a to především u zrnin a okopanin. V další části se potom věnuje podmínkám a zásadám pro jejich skladování. Pozornost je věnována zásadám, které je nutné dodržovat při zpracování bioproduktů a při jejich přepravě. Monografie zahrnuje zásady i příklady omezení, které platí při produkci biopotravin na bázi rostlinných surovin obecně či při zpracování přímo na farmě. |

| Emmer wheat cultivated by organic farmers is used as a component of some bio (organic) food products. Its positive influence on consumer health is caused by grain composition. In the set of 8 emmer wheat accessions, the main grain components, bread making characteristics and contents of health supporting chemical substances such as total dietary fibre content and its components, content of total polyphenols plus catechin and ferulic acid contents, vitamins of the B group and E plus total content of carotenoids were evaluated by standard methods. |

| Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer... |

| Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming system. In summary, our fi ndings show that einkorn (Triticum monococcum L.) and emmer wheat [Triticum dicoccum Schrank (Schuebl)] are resistant to powdery mildew and brown rust, spelt wheat (Triticum spelta L.) is less resistant to these two diseases, and the intermediate forms of bread wheat are very sensitive to such infestation. The varieties evaluated incline... |

| Soubor genetických zdrojů pšenice jednozrnky, dvouzrnky, jarní špaldy a přesívkových forem pšenice seté ze sbírek genobanky VÚRV Praha-Ruzyně, vypěstovaných v přesných polních pokusech v podmínkách ekologického systému tří pokusných lokalit (Praha-Ruzyně, Praha-Uhříněves a České Budějovice) byl hodnocen z pohledu obsahu N-látek v sušině zrna a zastoupení jednotlivých frakcí bílkovin zrna. Minoritní druhy pšenice se ve srovnání s kontrolními odrůdami pšenice seté vyznačovaly vyšším obsahem N-látek v sušině zrna, ale také rozdíly v zastoupení jednotlivých frakcí bílkovin ? především vyšším zastoupením nutričně cenných albuminů a globulinů a niţším zastoupením lepkových frakcí gliadinů a gluteninů. To naznačuje vyšší nutriční, ale horší technologickou,... |

| Organic farmers are obliged, in compliance with the valid legislation, to use seed originating from the organic production when establishing the crop stands. In a survey we found certified organic cereal seed is used on 6 %, conventional untreated seed on 37 %, and farm seed on 57 % (of the organically farmed area in the Czech Republic). The main reasons for that are as follows: the insufficient surface of land intended for the reproduction of organic seed, the low proportion of accepted seed coming from the accepted reproduction surface. Therefore, low-quality farm seed is used on a large proportion of organically farmed land, which has a negative effect on the yield level of the cereals. These observations were also confirmed by results obtained in a... |
