| Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time. |

| 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... |

| Global betrachtet war die Steigerung der Erträge zur Bekämpfung von Hunger in den vergangenen Jahrzehnten das Hauptziel in der Weizenzüchtung (Triticum aestivum L). Mit der Einführung von Verzwergungsgenen wurde der Ernteindex verbessert, der das Verhältnis Kornertrag zur oberirdischen Gesamtbiomasse darstellt. Begleitet von einer ansteigenden Zufuhr von Stickstoff- (N) und Phosphor- (P) Düngern und der Anwendung von Pestiziden hat dies zu einem beträchtlichen Ertragszuwachs geführt. Durch die jahrzehntelange Züchtung auf Hochertragssorten für den intensiven Anbau wurde möglicherweise das optimale Düngungsniveau im Weizenanbau verschoben und so indirekt auf Sorten mit einem höheren Nährstoffbedarf selektiert. Arbuskuläre Mykorrhiza können zur... |

| 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,... |

| Ziel des geplanten Vorhabens ist es, für die Bedingungen des ökologischen Landbaus besonders geeignete Sommer-Braugerstensorten zu züchten, da bislang keine Braugersten Sorten verfügbar sind, welche den besonderen Anforderungen des ökologischen Landbaus entsprechen. Spezielle Zuchtziele für den ökologischen Landbau sind Ertragsstabilität und gute Brau-Qualitäten unter low-input Bedingungen, Langstrohigkeit (gute Beikrautunterdrückung), hohe Toleranz gegenüber Gerstenflugbrand, Hartbrand und Streifenkrankheit. Fortgeschrittenes Zuchtmaterial wird an interessierte Pflanzenzüchter abgegeben, mit dem Ziel der Weiterentwicklung bis zur fertigen Sorte. Diese Weiterentwicklung ist jedoch nicht Teil des Projektes. Die Entwicklung der Zuchtziele erfolgt in enger... |

| Unpredictable climatic conditions and increasing pressure on non-renewable resources mean that alternative agricultural systems able to cope with increasing biotic and abiotic stresses, as well as external input costs, are needed. Sustainable agricultural systems should be self-regulating, characterized by a high degree of interand intra-specific diversity (Moreau 2010). Evolutionary breeding through the introduction of Composite Cross Populations (CCPs) increases intra-specific diversity, enabling CCPs to adapt to changing environmental conditions. Increasing interspecific diversity, through mixed cropping, also plays an important role in sustainable systems and suitable crops are needed that are able to cope with the increasing interspecific competition... |

| Mit dem Durchführungsbeschluss 2014/150/EU fordert die Europäische Kommission die Organisation eines zeitlich befristeten Experiments, welches Ausnahmen in Bezug auf das Inverkehrbringen von heterogenem Pflanzenmaterial zulässt. Das als Populationen bezeichnete heterogene Material muss die DUS-Kriterien der regulären Sortenzulassung nicht erfüllen. Stattdessen wird im Durchführungsbeschluss ein Mindestmaß für die Heterogenität der Populationen vorgeschrieben. In diesem Beitrag stellen wir Ergebnisse von Wertprüfungen der in Deutschland zugelassenen Winterweizen-Populationen vor, die 2016/17 und 2017/18 gemäß den Richtlinien für landwirtschaftliche Wertprüfungen und Sortenversuche des Bundessortenamts durchgeführt wurden. Erfasst wurden der Ertrag,... |

| Im Projekt zur Evaluierung von Genbanklinien von Lupinus albus L. konnte gezeigt werden, dass Variabilität in der natürlichen genetischen Resistenz gegen den pilzlichen Erreger der Anthraknose (Colletotrichum lupini) vorhanden ist. Acht Prüfstämme (BGRC-3931, LUP 2029, BGRC-3920, LUP 210, LUP B 1097, BGRC-3907, LUP 2042, BGRC-3907, LUP 2042, BGRC-3969) zeigten in zwei Untersuchungsjahren eine deutlich bessere Resistenz als der Durchschnitt. Der Stamm mit der besten Resistenz (BGRC-3931) zeigte im zweijährigen Durchschnitt etwa 25 Prozent der Anfälligkeit der anfälligsten Sorte. |

| Productivity in agriculture has more than tripled in developed countries since the 1950s. Beyond the success of plant breeding, the increased use of inorganic fertilizers, application of pesticides, and spread of irrigation also contributed to this success. However, impressive yield increases started to decline in the 1980s because of the lack of sustainability. One of the most beneficial ways to increase sustainability is organic agriculture. In such systems the prerequisite of successful farming is the availability of crop genotypes that perform well. However, selection of winter cereals for sub-optimal growing conditions is still neglected, and the organic seed market also lacks of information on credibly tested varieties suitable for organic... |

| Selection of cereal varieties suited to organic farming requires a different, but complementary, approach to that used when developing cereals for conventional high input systems. Selection is based on the interaction between a series of desirable plant and crop characteristics, in particular competitive ability against weeds. Certain key characteristics that are generically desirable for organic cereal varieties include: (1 good establishment ability, (2) high tillering ability, (3) increasing plant height, (4) planophile leaf habit, (5) high leaf index and (6) robustnesses in yield performance across sites. Our data strongly suggest that high crop ground cover is the most important feature for creating a highly competitive crop that also has consistency... |
