Description: Obwohl Raps ein ernährungsphysiologisch sehr wertvolles Speiseöl bei gleichzeitig hohem Proteingehalt liefert, ist seine Bedeutung in der organischen Landwirtschaft unterdurchschnittlich gering. Dieses wird mit dem im Vergleich zum konventionellen Anbau höheren Ertragsrisiko begründet. Biotische und abiotische Stressoren, eine lange Vegetationsperiode sowie die hohen Ansprüche an die Stickstoffversorgung stellen im organischen Landbau besondere Herausforderungen dar. Die hohe Nachfrage nach dem ernährungsphysiologisch wertvollen Speiseöl und pflanzlichen Protein aus dem organischen Landbau kann daher nicht hinreichend gedeckt werden. In dem Projekt sollen Nachkommen von leistungsfähigen Eltern, die mit nicht-angepasstem Material (Resyntheselinien) gekreuzt wurden, auf deren Eignung für den organischen Landbau getestet werden. Bei diesem Ausgangsmaterial handelt es sich um heterogene Bestände, (Evolutionsramsche) welche sich durch einen Anbau von mehr als eineinhalb Jahrzehnten unter organischen Anbaubedingungen entwickelt angepasst haben. In dem Projekt sollen Teilpopulationen der Evolutionsramsche phänotypisch untersucht werden. Insbesondere die Wurzel- und Sprossarchitekturmerkmale sollen in Verbindung mit dem Gesamtertrag Informationen und Kennzahlen liefern, welche mittels einer anschließenden Genotypisierung auf dem Genom nachverfolgt, kartiert und dadurch nutzbar gemacht werden. Insbesondere werden die Ertragsleistung (Öl und Protein), Wasser- und Nährstoffnutzungseffizienz von den Evolutionsramschen festgestellt und direkt mit aktuellen Sorten und ausgewählten Linien aus den Ramschpopulationen verglichen. Am Ende des Projekts steht genetisches Material für den Aufbau von heterogenen Populationen bzw. für eine direkte Sortenentwicklung zu Verfügung.

Title: Rapeseed for organic farming - use of adapted evolutionary rhizomes to improve resource efficiency and climate adaptation
Description: Rapeseed provides a nutritionally high-quality edible oil and protein for many uses and is a very important energy crop in the current energy mix of renewable raw materials. In addition to its high oil content of up to 45%, rapeseed also has a similarly high protein content to chickpeas of up to 25% and will play a more important role in protein supply and food security in the future. By repeating the crossing of B. oleracea and B. rapa (resyntheses) and crossing them into the Brassica napus elite material, the genetic variability of oilseed rape can be significantly expanded, especially in traits of adaptation to different ecological conditions. In the project, progeny of high-yielding parents crossed with non-adapted material (resynthesis lines) will be tested for their suitability for organic farming. The starting material for the tests is heterogeneous stocks, evolutionary strains that have developed over more than a decade and a half under organic cultivation conditions and have adapted to the cultivation methods. In particular, yield performance (oil and protein), water and nutrient use efficiency are determined from the evolutionary ramets and compared directly with current varieties and selected lines from the ramet populations. The approach chosen here involves a combination of different factors that could lead to an increase in drought stress tolerance and N uptake and utilization efficiency in rapeseed cultivation. Thus, the objectives of this project can be summarized as follows: (i) Expansion of the gene pool through the use of resynthesis lines and based on this (ii) Investigation of nutrient efficiency (iii) Improvement of drought tolerance with consideration of root characteristics (iv) Composition of the crop in terms of protein and oil content.

Title: Rapeseed for organic farming - use of evolutionary selection for adaptation to improve resource efficiency and climate resilience
Description: Rapeseed provides multi-purpose edible oil and protein with high nutritional quality and is a very important energy crop in the current mix of renewable resources. In addition to a high oil content of up to 45%, rapeseed also has a high protein content (up to 25%, similar to chickpea), and is expected to play an increasingly important role in protein supply and food security in the future. By resynthesizing rapeseed by crossing between progenitor species B. oleracea and B. rapa, followed by crossing these lines into the Brassica napus elite germplasm pool, the genetic variability of rapeseed can be significantly expanded, particularly in terms of adaptation to different ecological conditions. In this project, progeny of high-yielding parents that have been crossed with non-adapted resynthesised lines will be tested for their suitability for low-input agricultural conditions. Initial crosses between elite and resynthesised germplasm were further cultivated under organic cultivation conditions for more than a decade and a half to produce novel germplasm putatively adapted to these conditions. In particular, yield performance (oil and protein), water and nutrient use efficiency will be determined for the novel germplasm, their parent lines as well as current varieties as a control. This selected breeding approach comprises a combination of different factors, which could lead to an increase in drought stress tolerance and in N uptake and utilization efficiency in rapeseed. Thus, the objectives of this project can be summarized as follows: (i). The expansion of the rapeseed gene pool via the use of resynthesised lines and a long-term selective strategy to produce novel germplasm putatively adapted to low-input agriculture (ii). The investigation of nutrient use efficiency in this novel germplasm (iii). The investigation of drought tolerance in relation to root traits in this novel germplasm (iv). The evaluation of the novel germplasm for protein and oil content
