| Der har i den danske landbrugspresse i sommeren 2008 været en debat om fordele og ulemper ved anvendelse af egen udsæd i forhold til anvendelse af certificeret udsæd. Landscenteret har eksempelvis beregnet, at konventionelle landmænd kan spare 265-350 kr/ha ved at bruge certificeret udsæd på 10% af markerne, og bruge egen såsæd på resten. Omvendt fremhæver såsædsbranchen for det første, at den danske model, hvor langt hovedparten af landmændene køber certificeret såsæd er med til at finansiere dansk planteforædling, og dermed til at vi har de bedste sorter, og for det andet et certificeret såsæd er af en bedre kvalitet bl.a. på grund af bejdsning. I økologisk landbrug er forholdene anderledes end i det konventionelle landbrug. |

| Adaptasyon kabiliyetinin yüksekliği sayesinde, çileğin (Fragaria X ananassa Duch.) çok farklı ekolojilerde yetiştiriciliği yapılmaktadır. Çilek de diğer taze meyve sebzelerde olduğu gibi, özellikle yetiştirme döneminde hüküm süren fungal hastalıklar nedeniyle önemli ürün kayıplarına uğramaktadır. Botrytis cinerea Pers. ex Fr. (teleomorf; Botryotinia fuckeliana (de Bary) Whetzel) çilekte çiçek veya meyvede kurşuni küf hastalığına sebep olmakta, hem hasat öncesinde hem de hasat sonrasında çilekteki başlıca ürün kayıpları bu hastalıktan kaynaklanmaktadır. Hastalık ile mücadelede çiçeklenme dönemindeki fungisit uygulamaları hastalığın engellenmesinde kullanılan en etkili ve yaygın yöntemdir. Ancak, B. cinerea’nın fungisitlere karşı kazandığı dayanıklılık,... |

| Organic plant production is currently challenged by several pressure factors. Along with perennial problems such as weed control, climate change is threatening to affect crop production through increasing weather variability. Plant breeding is a crucial factor in creating organic crop production systems that can better cope with such interacting stresses and producers need crop varieties with (a) good resistance against pests and diseases, esp. seed borne diseases; (b) the ability to react to environmental, esp. climatic variability; and (c) high competitiveness against weeds. COBRA aims to support and develop organic plant breeding and seed production with a focus on increasing the use and potential of plant material with High genetic Diversity (Hi-D) in... |

| The phytochemicals including flavonoids and phenolic acids mainly contained in the outer layer of the kernels are key factors responsible for the biofunctionality of whole grains. The phytochemical profiles of twelve grain samples comprising 6 wheats, 3 barleys and 3 oats were studied for comparative evaluation of their antioxidant properties. Total phenolic content (TPC) and antioxidant activities (DPPH and ORAC) of the grain extracts were measured. The bound phenolic acids were identified and quantified using HPLC and mass spectrometry. The flavonoids in different grain were analyzed using HPLC and tandem mass spectrometric techniques. TPC in acidified methanol extracts ranged from 164 to 226, 264-391, and 308-331 mg/100 g for wheat, oats and barley,... |

| Das hier beschriebene Projekt ist Teil eines Verbundvorhabens, das folgende Teilprojekte umfasst: FKZ 12OE021, FKZ 12OE022 und FKZ 12OE023. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/id/saved_search/1498. Für den ökologischen Landbau sind widerstandsfähige Sorten erforderlich, die auch dann marktfähige Ware mit hoher Qualität und akzeptablen Erträgen hervorbringen, wenn sie Stressfaktoren wie suboptimaler Nährstoffversorgung, Trockenheit, Befallsdruck durch Schaderreger oder Beikrautkonkurrenz ausgesetzt sind. Ziel des Projektes COBRA ist es, die ökologische Züchtung und Saatgutproduktion in Europa zu unterstützen und damit die... |

| Our apple breeding program is based entirely on the results of our work to safeguard, evaluate and valorize the rich heritage of apple tree genetic resources in our regions. Since 1975, no fewer than 1800 introductions have been collected in our collections and, taking into account duplicates, errors and synonyms, this represents a total of about 850 distinct cultivars. These are systematically evaluated in experimental orchards that do not undergo any treatment. Some cultivars that are highlighted for their high level of resistance to the main diseases as well as for their agronomic and quality characteristics of trees and fruits are used as parents. Our priorities are mainly focused on the expansion of the apple's genetic base, polygenic resistance to... |

| Developing crop varieties that are less dependent on the heavy application of synthetic fertilizers is essential for the sustainability of agriculture. Here we report the development of a new rice cultivar, the first of its kind possessing the general criteria for an organic rice variety, at the same time suitable for chemical agriculture as well, and with favourable cooking and nutritive qualities. The method adopted for cultivar development was a combined strategy of pedigree breeding, organic plant breeding, and farmer participatory breeding approaches. Considering its high grain and straw yield potential even under organic management and unfavorable soil conditions, and its other favorable quality and organic varietal traits, farmers have started... |

| All over the world, Thule III is used as differential variety for the resistance gene Bt-13 against common bunt. It can therefore be strange that I can question whether Thule III have Bt-13, so let me elaborate the question. I also use Thule III as a standard for Bt-13, and I got this variety from GRIN PI 181463. This variety does indeed have a major gene against common bunt and since we all use it as a standard for Bt-13 this gene is per definition Bt-13. What still puzzles me is that this variety does not look like Thule III. It says in the GRIN database that it is of Swedish origin with the pedigree Thule II/Sammet. PI 181463 is a short, lodging and weak variety with a very poor winter hardiness, and it does not at all look like a Swedish winter wheat.... |

| 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... |
