| Introduction Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have... |

| Organic farming requires cultivars that are specifically adapted to this low input cropping system. Hence, organic farmers and scientists joined in a participatory breeding approach to develop region-specific genotypes of spring faba bean for organic conditions in Germany. A set of 49 genotypes with contrasting degrees of heterozygosity and heterogeneity was used in field trials across five locations in Germany during 3 years 2004, 2005 and 2006. The material involved 18 inbred lines, their 18 polycross progenies, one blend of inbred lines, one blend of polycross progenies, one blend of hybrids and ten checks. Inbred lines are uniform, thus giving the option to be specifically adapted; whereas the polycross progenies and synthetics (Syn-1; predicted from... |

| The oil of safflower (Carthamus tinctorius L.) is a valuable oil for human nutrition. It contains a high amount of unsaturated fatty acids, in particular linoleic acid (up to 90 %). There is a great demand for ecologically produced oil in Germany, though oil crops are cultivated on 2 % of the ecological acreage. In Germany, hardly any variety test exists, moreover there has been no breeding efforts so far, although genetic variation in safflower is large. The aim of this study was the development of a rapid and non-destructive method to determine oil content in safflower seed using NIRS (Near-Infrared Reflectance Spectroscopy). A total of 203 seed samples were scanned with NIRS to estimate the oil content. Intact seeds as well as milled seeds were... |

| Ziel des Forschungsvorhabens ist es, die im Handel erhältliche Sommergerste-Sorten auf ihrer Anfälligkeit gegenüber der saatgutübertragbaren Streifenkrankheit zu untersuchen. 55 Sommergerstensorten und fünf genetische Ressourcen mit Streifenkrankheitsresistenzen werden bei Darzau/Ost-Niedersachsen über zwei Jahre und auf dem Dottenfelderhof/Wetterau ein Jahr lang einem natürlichen Befall ausgesetzt. Parallel dazu wird eine hoch befallenen Sorte angebaut. Im Folgejahr wird der Befall im Nachbau der Sorten auf beiden Standorten geprüft. Aus dem Ergebnis können Sortenempfehlungen für eine kontinuierliche Vermehrung unter ökologischen Anbaubedingungen abgeleitet und Schätzungen für eine maximal zu erwartende Ertragsminderung im Falle des Auftretens der... |

| Die Sonnenblume ist die wichtigste ölliefernde Pflanze im Öko-Landbau. Da ihre Samen neben einem hohen Fettgehalt auch einen beachtlichen Anteil an Eiweiß enthalten, sollten in diesem Projekt grundlegende Fragen beantwortet werden, damit die praktische Pflanzenzüchtung Strategien entwickeln kann, um Sonnenblumen mit einem erhöhten Proteinertrag züchten zu können. Aus 235 untersuchten Sonnenblumenlinien wurden 23 Linien mit unterschiedlichen Proteingehalten gewählt, die als Kreuzungseltern von 105 Testhybriden dienten. Die Testhybriden und die Elternlinien wurden in 2 Jahren an insgesamt 5 Umwelten in Leistungsprüfungen auf anerkannt ökologischen Flächen auf ihre Ertrags- und Qualitätsmerkmale geprüft. Zur Ermittlung des Proteingehaltes wurde die... |

| For the organic farmers there is important question which varieties of wheat are right for organic farming in Less Favoured Areas. Modern varieties of wheat are bred in the conditions of conventional (high imput) farming. That is why the organic farmers asked about the suitability of land races of soft wheat (Triticum aestivum L.) or different species like emmer wheat grown in the past (Triticum dicoccum SCHUEBL). The paper results from the study of fourty land races, two intermediate and ten modern varieties of soft wheat in comparison to ten land races of emmer wheat at two locations in the Czech Republic. We evaluated tuft shape, length of plant, length and width of flag leaf, length and density of spike and awnedness. The modern varieties of soft... |

| Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties... |

| Evidence of greater nutritional value in organic crops is currently a subject of intense debate. Our objectives in this study were to test for grain mineral concentration in 35 winter wheat cultivars in paired organic and conventional systems, and to determine the influence of cultivar, soil characteristics and farming system on mineral concentration. Here we report preliminary results that show that the grain mineral concentration in organic wheat was higher for copper (Cu), magnesium (Mg), manganese (Mn), phosphorus (P) and zinc (Zn) and lower in calcium (Ca), than the grain mineral concentration in conventional wheat. No difference was found between systems for iron (Fe) concentration. Cultivar was significant in determining mineral concentration for... |

| Driven by an increasing demand for GMO-free soya as food or fodder, the production of organic Soybeans increases, also in high latitudes. As a legume crop, soya needs specific rhizobia bacteria to be supplied by biological nitrogen fixation (BNF). Since most soils lack the soy-specific strains, bacteria material is usually added manually. We set up a field trial with 5 site-years to investigate the benefit of this inoculation procedure in two different environments (humid, Germany/semi-arid, Russia) under organic farming conditions. Overall 5 different varieties were used (at each site 2 individual and 1 joint) to compare inoculation against untreated control. Leaf chlorophyll as indicator for BNF was determined by a SPAD-502. To make the SPADmeter... |

| White lupin (Lupinus albus) is an interesting crop for use as food, feed, forage or cover crop. However, its cultivation is currently limited because of its high susceptibility to the seed-borne pathogen Colletotrichum lupini, causal agent of lupin anthracnose. Twenty-eight seed treatments were studied here for their efficacy against lupin anthracnose, consisting of 4 hot water, 5 steam, 4 dry heat, 5 electron, 2 plant-based and 2 microbial treatments, as well as 6 controls. Experiments were divided into a germination assay and a pot-based disease assessment experiment. Treatment effects were studied by visual assessments of plants, culture-based incubation of plant tissue and quantitative polymerase chain reaction (qPCR)-based detection of Colletotrichum... |

| Wie jede andere Leguminose, kann auch die Sojabohne (Glycine max (L.) Merr.) mit Hilfe von Soja-spezifischen Knöllchenbakterien (Bradyrhizobium japonicum) Luft-Stickstoff binden. Da die Bradyrhizobien natürlicherweise nicht in den mitteleuropäischen Böden vorkommen, müssen die Samen der Sojabohne mit kommerziell verfügbaren Bradyrhizobien-Impfpräparaten inokuliert werden. Beim Anbau hat sich in den letzten Jahren jedoch gezeigt, dass die Inokulation vor allem in kühleren Klimaten bei einzelnen Präparaten zu unzuverlässiger Knöllchenbildung und damit ungenügender Stickstoffbindung führen kann. Ziel dieser Arbeit ist es, die Eignung kommerziell verfügbarer Bradyrhizobien-Impfpräparate zur Inokulation der Sojabohne zu prüfen. |

| Baking quality is a major problem of wheat production in organic farming in Germany. The main reason is low protein content, but also different gluten characteristics. The aim of our investigations was to verify, whether selection of varieties with special adaptation to organic farming (or OF systems with particular low input) is advantageous. 66 Genotypes of winter wheat (registered German varieties, breeding lines, older varieties and varieties bred for organic farming) were compared in 5 environments over two years. Yield, protein content and quality parameters were assessed. Aptitude to LI- or HI- conditions was determined using intravarietal linear regression. While selection for special adaptation proved to be superior for yield and protein yield,... |

| Aufgrund seines potentiell hohen Carotingehaltes ist Einkorn von Natur aus bereits als funktionelles Lebensmittel anzusehen (functional food). Die Eignung von Einkorn zur Herstellung von Teig- und Backwaren ist jedoch sortenabhängig und zeigt unterschiedliche Ausprägungen. Derzeit verfügbare Sorten sind in den Klebereigenschaften sehr weich. Doch bereits BORGHI et al. (1996) fanden Muster mit außerordentlich hohen Sedimentationswerten, was auf einen festeren Kleber schließen lässt. Es wurden in der Vergangenheit drei Sorten entwickelt, die inzwischen an verschiedenen Orten in Deutschland angebaut werden. Sie sind in ihren agronomischen Eigenschaften schon weit fortgeschritten, verfügen aber noch nicht über die von den Bäckern gewünschte Kombination der... |
