| The Institute of Fruit Breeding has a long tradition in breeding resistant apple cultivars. Systematic resistance breeding started in the 1930 ties in Müncheberg. Material developed in Müncheberg was transferred in the 1970 ties to the Institute for Fruit Research, the antecessor of the Institute of Fruit Breeding. Based on this material, a couple of multiple resistant cultivars were generated. The time schedule for combining biotic and abiotic resistant traits which demonstrates the long-lasting period necessary for systematic resistance breeding is given. An overview of resistant cultivars of Dresden-Pillnitz and the respective resistant traits is presented. This assortment of cultivars was developed to provide a resistant cultivar for each ripening... |

| An zwei Standorten des Ökologischen Landbaus (Neu-Eichenberg, Nordhessen: mittlerer bis schwerer Boden; Queck, Osthessen: leichter Boden) wurden Feldversuche mit Möhren durchgeführt, um sechs samenfeste Sorten und sechs Hybriden auf ihre Anbautauglichkeit zu prüfen. Außer der Roh- und Handelswarenerträge wurden die Einheitlichkeit des Erntegutes (cv%) bestimmt und die Gehalte an Mineralstoffen (K, Ca, P, Mg) und Zuckern (D-Glucose, D-Fructose, Saccharose) analysiert. Auch sogenannte Bildschaffende Methoden (Kupferchloridkristallisation, Steigbild, Rundfilterchromatogramm) kamen zur Anwendung. Die untersuchten Hybriden erzielten Mehrerträge von 25 bis 29% und in den meisten Fällen auch gleichmäßiger lange Rüben als die Samenfesten. Die... |

| The possibility of improving resistance in pea against the root pathogen Aphanomyces euteiches using composite cross as a breeding and selection method was examined. In order to maintain acceptable agricultural features and high yield 6 out of the 8 parental varieties in the present composite-cross were commercially grown varieties. Populations of the composite cross were grown up to five generations with selection pressure in soil heavily infested with pea root pathogens or without selection pressure on soil free of pea root pathogens. Yield of populations of the F9 and F10 generations of the composite cross grown with selection pressure was on average 35% higher than that of the population obtained without selection pressure as well as the average yield... |

| Die Ausbreitung von Flugbrand (Ustilago nuda (Jens.) Rostr.) wurde über drei Vegetationsperioden in einem Zuchtgarten unter ökologischer Bewirtschaftung anhand spaltender Generation von Sommergerste bis zur F9 unter Einbeziehung von Zuchtstämmen mit resistenten Eltern, ergänzt um anfällige Sorten und genetische Ressourcen untersucht. Saatstreifen mit Flugbrandbefall wurden zur besseren Ausbreitung der Krankheit in einigen Bereichten eingefügt, was sich als geeignet erwiesen hat. Parzellen mit befallsfreiem Saatgut einer anfälligen Sorte wurden zwischen die spaltenden Zuchtstämme eingefügt, um den Grad der Ausbreitung festzustellen. Beginnend in F5 wurden ausgelesene Zuchtstämme ohne Befall mit einer Flugbrandsporensuspension in die Blüten einzelner Ähren... |

| Production of high quality organic vegetable seeds encounters several challenges. Research is performed to support seed companies in producing vigorous and healthy organic vegetable seeds. Examples are provided with respect to research on seed vigour, determining critical control points to avoid disease transmission to the seeds, seed treatments with natu-ral compounds, new seed sorting techniques and enhancement of the natural plant defence. It is noticed that the restrictions in EU regulation 2092/91 on organic production are at present blocking the use of promising natural and sustainable components for seed treatments. |

| ORGSEED undersøgelserne viser, at der findes en række vårbygsorter med lovende resistens overfor stribesyge og nøgenbrand. Under dyrkningsforhold, hvor de to sygdomme betragtes som nøgle-problemer, burde sortsvalget derfor tager hensyn til de resistensoplysninger, som ORGSEED projektet har tilvejebragt. Men det skal huskes, at muligheden for at bruge sortsresistens ikke kommer af sig selv. Det kræver stadig årvågenhed med hensyn til at følge skift i sorternes sygdomsreaktion over tid og dette kræver fortløbende resistens-screening og –afprøvning af markedsførte sorter såvel som af forædlingsmaterialet. |
