Genetic mapping of QTL controlling salt tolerance and glucosinolates in Brassica napus and Brassica oleracea
(2014-12-05)Brassica species are of great importance for human food and animal feed supply. Brassica napus occupies the second position among the oilseed crops behind soybean. Brassica oleracea includes numerous species of vegetables. ... -
Factors regulating the population dynamics and damage potential of pollen beetle (Meligethes aeneus F.) on crops of oilseed rape
(2014-05-15)The pollen beetle Meligethes aeneus (Fabricius) (Col.: Nitidulidae) is one of the most important pests of oilseed brassicas in Europe. Due to extensive use of pyrethroids and the limited supply of registered insecticide ... -
Studies on Ramularia Leaf Spots on Barley - Resistance Phenotyping, Epidemiology and Pathogenicity
(2013-10-31)The deuteromycete, Ramularia collo-cygni (Rcc) has gained increasing importance as the causal agent of a novel leaf spot disease, Ramularia leaf spot (RLS), on barley. The disease occurs conspicuously late in the growing ... -
Improvement of Winter Oilseed Rape Resistance to Verticillium longisporum - Assessment of Field Resistance and Characterization of Ultrastructural Plant Responses
(2013-07-04)Recent years have seen an intensification of oilseed rape (OSR) cultivation, which, together with shorter crop rotations has led to a rapid increase in infestation by the soil-borne vascular pathogen V. longisporum. The ... -
Charakterisierung von resistenz-überwindenden Isolaten des Beet necrotic yellow vein virus (BNYVV) in Zuckerrüben und Stabilität der Resistenz in Abhängigkeit von Umweltbedingungen
(2013-06-18)Beet necrotic yellow vein virus (BNYVV) is the causal agent of rhizomania (root madness) in sugar beet and is spread to all sugar beet growing areas worldwide. The virus is transmitted by the soil-borne plasmodiophoromycete ... -
Genetic variation and inheritance of secondary seed dormancy in winter oilseed rape (Brassica napus L.)
(2012-11-29)Secondary seed dormancy in oilseed rape is a phenomenon that allows seeds to survive in the soil for many years without germination. Following soil cultivation, dormant seeds may germinate in subsequent years and are the ... -
Phänotypisierung von Raps- und anderen Brassica-Genotypen zur Identifizierung von Resistenzquellen gegenüber Sclerotinia sclerotiorum
(2012-02-28)The aim of this work was the development of suitable screening methods for resistance evaluation of oilseed rape cultivars against S. sclerotiorum. With these methods, possible sources of ... -
Molecular and functional characterization of potential pathogenicity related genes from <i>Verticillium longisporum</i>
(2012-02-17)The genus Verticillium includes many plant pathogenic species that cause serious economic losses through the infection of host plants, and it belong to one of the most widespread groups of ... -
Colonization of maize with Fusarium spp. and mycotoxin accumulation
(2012-01-06)Ear rot caused by Fusarium spp. is a serious disease of maize plants worldwide, which can be divided in two types: Red ear rot or Gibberella ear rot (GER), and Pink ear rot or Fusarium ear rot (FER). Apart from impairment ... -
Brassica - Wildarten als neue genetische Ressource für die Rapszüchtung
(2011-12-14)The genetic base in the material which is available in rapeseed breeding is very limited in comparison with other crops such as wheat or maize which are used for a very long time by humans. ... -
Breeding for a reduced glucosinolate content in the green mass of rapeseed to improve its suitability for biogas production
(2011-08-03)Brassica napus L., a plant that belongs to the Brassicaceae family is one of the main oil crops. Inside its seeds glucosinolates appear to be the main secondary glycoside, sugar containing ... -
Fusarium in Zuckerrüben - Artspektrum, Pathogenität und Mykotoxinbildung sowie Kreuzpathogenität in Weizen
(2011-03-02)Fusarium spp. can infect sugar beets in all growth stages and during storage. Especially in the U.S., root and white sugar yield is reduced by Fusarium Yellows. Fusarium spp. are also ... -
Effect of Brassica genotype on the infestation by cabbage stem weevil Ceutorhynchus pallidactylus (Mrsh.) (Col.: Curculionidae) and the parasitism of stem weevil larvae
(2010-12-21)The search for plant resistance to insect pests in oilseed rape (Brassica napus L. var. oleifera Metzg.) is still in an early stage of development. In this study, a wide spectrum of ... -
Comparative QTL mapping in diploid and alloploid Brassica species to analyze fixed heterosis
(2010-10-22)The spontaneous hybridization of related species by combining their genomes (alloploidy) has played a prominent role in plant evolution. Main reasons for the success of allopolyploids are ... -
Genetische und agronomische Charakterisierung von Raps-Mutanten mit gesteigertem Ölsäuregehalt
(2010-04-15)The main breeding objectives of rapeseed (Brassica napus L.) have always been to increase yield, yield components, disease and pest resistance and more recently the seed quality too. The ... -
Einfluss von Kohlfliegenbefall auf die Infektion und Schadwirkung von Verticillium longisporum und Phoma lingam an Raps
(2009-07-10)The present work is dealing with the impact of cabbage root fly (Delia radicum) on infections and damage potential of V. longisporum and P. lingam on oilseed rape. Between 2005 and 2008 ... -
