Última Züchtung krankheitsresistenter Apfelsorten Organic Eprints Kellerhals, Markus; Patocchi, Andrea; Szalatnay, David; Hunziker, Kaspar; Frey, Jürg; Duffy, Brion. Breeding high quality apples combined with excellent agronomic features promotes sustainable production systems. This approach includes durable genetic disease resistance against scab (Venturia inaequalis), powdery mildew (Podosphaera leucotricha) and fire blight (Erwinia amylovora). Glasshouse screening of advanced selections and traditional cultivars with a shoot inoculation test for fire blight resistance highlighted considerable differences. We report on approaches for breeding new high quality scab and mildew resistant and fire blight tolerant varieties including markerassisted selection (MAS) and on promising advanced selections.

Ano: 2009 URL: http://orgprints.org/14428/1/Kellerhals_14428.pdf Hofdüngereinsatz im Gemüsebau Organic Eprints Koller, Martin; Duffy, Brion; Widmer, Franco. Mist und Gülle sind wertvolle Nährstofflieferanten. Aus Hygiene- und Gesundheitsgründen braucht es jedoch einen sachgerechten Umgang mit diesen organischen Düngern. Denn in Frischgülle und -mist kommen natürlicherweise Krankheitserreger vor,die auch Menschen betreffen können. Bei sachgerechter Anwendung können die Risiken aber stark vermindert werden.

Ano: 2011 URL: http://orgprints.org/20393/1/SchweizerBauer_Hofd%C3%BCnger_zu_Gem%C3%BCse_27Juli.pdf Use of genetic resources and partial resistances for apple breeding Organic Eprints Kellerhals, Markus; Duffy, Brion. Modern apple breeding strategies are mainly considering the most advanced selections and cultivars as parents. This tends to lead to a narrowed genetic basis. The introgression of traditional varieties and accessions of the gene pool is often feared due to undesirable characteristics that might be incorporated. However, there is scope for considering a wider genetic basis in apple breeding to support sustainable fruit production systems. The focus at Agroscope Changins-Wädenswil (ACW) is put on high fruit quality combined with low susceptibility to scab (Venturia inaequalis), fire blight (Erwinia amylovora), and powdery mildew (Podosphaera leucotricha). The Swiss scab and fire blight resistance research programs are focused on developing and applying...

Ano: 2006 URL: http://orgprints.org/13854/1/ecofruit_12th_27.pdf Modern approaches for breeding high quality apples with durable resistance to scab, powdery mildew and fire blight Organic Eprints Kellerhals, Markus; Patocchi, Andrea; Duffy, Brion; Frey, Jürg. New methods to allow for more precise selection of tree and fruit characters in breeding programmes were developed in recent years. Marker-assisted selection (MAS) is common practice in the ACW apple breeding programme at Wädenswil. Genetic markers can reduce the number of plants and the time required for evaluation, thus new varieties become commercially available sooner. How can this molecular selection method reasonably be applied in an apple breeding programme? Application of phenotypic and molecular selection techniques in the ACW apple breeding programme and results are presented.

Hofdünger sind ein wertvoller Nährstofflieferant. Natürlicherweise enthalten sie Krankheitserreger, die auch den Menschen treffen können. Im Rahmen des Forschungsprojekts Pathorganic wurden Empfehlungen für einen sicheren Einsatz erarbeitet.
