Description: Gesunde und leistungsfähige Wurzelsysteme der angebauten Kulturen sind unabdingbare Voraussetzungen für sichere und hohe Erträge. Im Projekt sollen Ertrag und Ertragsstabilität Schmalblättriger Lupinen[1] (Lupinus angustifolius) durch Selektion auf Wurzelmerkmale maßgeblich verbessert werden. Neben der Erfassung der Wurzelarchitektur und der Wurzelwachstumsgeschwindigkeit in Rhizotronen soll insbesondere der Wurzelchemotyp (Wurzelexsudate und Rhizodeposite) und dessen Einfluss auf die Rhizosphäre, Knöllchenbildung und Phosphataufschluss mittels GC/MS erfasst werden. Die genetischen Grundlagen sollen mittels differenzieller Expressionsprofile über RNA-Seq-Vergleiche und quantitative PCR mit mRNA analysiert werden. Die Daten werden züchterisch genutzt, um die wurzelbezogenen Merkmale aus bitteren Formen in alkaloidarme Formen der Schmalblättrigen Lupine zu überführen und dort mit wichtigen Domestikations- und Qualitätsmerkmalen zu kombinieren. Dabei sollen die Domestikationsmerkmale (z.B. Platzfestigkeit, Weichschaligkeit) über molekulare Marker verfolgt und selektiert werden. Die Qualitätsmerkmale Protein- und Alkaloidgehalt werden über GC/MS und Einzelkorn NIRS erfasst und in die Selektion einbezogen. Darüber hinaus sollen agronomische Eigenschaften, wie Hochwüchsigkeit, Standfestigkeit und Spätreife berücksichtigt werden, die sich positiv auf zukünftige Anbauformen wie z.B. Mischanbau auswirken können. Das Projekt zielt darauf ab, neuartige Sorten der Schmalblättrigen Lupine zur Verfügung zu stellen, die über leistungsfähige Wurzelsysteme mit neuartigen Eigenschaften neue Anbaugebiete erschließen und deutlich verbesserte Kornerträge und Ertragsstabilitäten liefern können. Die dem beantragenden Konsortium vorliegenden genetischen Ressourcen aus vorangegangenen Projekten und die darin gefundenen Merkmalsausprägungen für z.B. Boden-pH-Toleranz, Pflanzenarchitektur und Hülsenansatz sind hierzu hervorragend geeignet.

Title: High-performance varieties of narrow-leaved lupin (Lupinus angustifolius) by unlocking the genetic potential of root traits and rhizosphere interactions
Description: Healthy and efficient root systems of cultivated crops are indispensable prerequisites for reliable and high yields. The project aims to significantly improve the yield and yield stability of narrow-leaved lupins (Lupinus angustifolius) by selecting for root characteristics. In addition to recording the root architecture and root growth rate in rhizotrons, the root chemotype (root exudates and rhizodeposits) and its influence on the rhizosphere, nodule formation and phosphate mobilisation will be analysed using GC/MS. The genetic basis will be analysed by means of differential expression profiles using RNA-Seq comparisons and quantitative PCR with mRNA. The data will be used for breeding purposes to transfer the root-related traits from bitter forms to low-alkaloid forms of narrow-leaved lupin and combine them with important domestication and quality traits. The domestication traits (e.g. pod shattering resistance, soft-seeds) are to be tracked and selected using molecular markers. The quality characteristics protein and alkaloid content are recorded via GC/MS and single grain NIRS and included in the selection. In addition, agronomic traits such as vigour, stability and late maturity will be taken into account, which may have a positive impact on future forms of cultivation such as mixed cropping. The project aims to provide novel varieties of narrow-leaved lupin that can open up new cultivation areas and deliver significantly improved grain yields and yield stability thanks to powerful root systems with novel characteristics. The genetic resources available to the applicant consortium from previous projects and the traits found therein, e.g. for soil pH tolerance, plant architecture and pod set, are ideally suited for this purpose.
