Genetische Analyse des bovinen bilateralen konvergenten Strabismus mit Exophthalmus des Holstein Rindes sowie der equinen hereditären Mikrophthalmie
(2021-06-24)In the context of the present thesis, two different hereditary diseases of the eyes were investigated. Bilateral convergent strabismus with exophthalmos (BCSE) in Holstein cattle and equine microphthalmia. The aim of the ... -
Genetische Analyse von Heterosis im jüngsten Stadium einer Pflanze, als Embryo, am Beispiel der Fababohne (<i>Vicia faba </i>L.)
(2007-12-17)Heterosis, defined as the surplus performance of the hybrid over the mean of its parents, is a well analysed phenomenon, and still since today its causes and modes of action are not yet ... -
Genetische Analyse von Verhaltensmerkmalen beim Schwein
(2016-01-12)This thesis deals with different behaviour parameters in pigs, which were measured during different production periods. The aims of the thesis were to investigate traits that characterise agonistic behaviour as well as ... -
Genetische Analysen für eine markergestützte Verbesserung der Trockenstresstoleranz von Winterackerbohnen
(2014-08-04)In this analysis, aiming to prepare for marker-assisted selection of drought tolerance in autumn sown faba bean (Vicia faba L.), 196 winter-type and four spring-type inbred lines were genotyped. Physiological traits such ... -
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 ... -
Genetische Variation und Vererbung von Sinapinsäure-Verbindungen im Raps (<i>Brassica napus L.</i>)
(2005-12-09)Increasing the meal and protein quality for food and feed purposes is an important breeding goal for winter rapeseed (Brassica napus L.). Rapeseed meal has a high content of ... -
Genomanalyse beim landwirtschaftlichen Nutztier
(2008-05-09)The thesis is divided into two parts. The studies presented in the first part describe the results of molecular analyses on the inheritance of congenital inguinal and scrotal hernia in the pig. The second part covers ... -
Genome sequencing and phylogenetic analyses of common and dwarf bunt of wheat provide insights into their genomic diversity and species boundaries, and enable the development of a detection assay for Tilletia controversa
(2021-11-23)The fungal genus Tilletia is generally recognized by the production of darkly pigmented teliospores, which replace mostly the host ovary. Currently, nearly 200 species of Tilletia species infecting Poaceae are included in ... -
Genomic and conventional evaluations for fertility traits in pigs
(2019-01-17)The aim of genomic selection (GS) is to predict breeding values with high accuracy for young animals (without own phenotypic record) as early as possible. GS can increase the accuracy of the breeding values at the time ... -
Genomic selection in farm animals: accuracy of prediction and applications with imputed whole-genome sequencing data in chicken
(2016-03-15)Genomic prediction has been successfully applied in many livestock breeding schemes, based on different densities of single nucleotide polymorphism (SNP) array data. With the availability of whole-genome sequencing (WGS) ... -
Genotype by temperature interaction effects on sex determination in zebrafish (Danio rerio)
(2019-12-06)The mechanism of sex determination and gonad differentiation in zebrafish is one of the more challenging research questions and complex puzzles in biology. The regulation of sexual dimorphism in this species is not yet ... -
Genotypic and phenotypic analysis of the allelic diversity in candidate genes for oil content in exotic plant materials of rapeseed (Brassica napus L.)
(2014-11-26)Novel alleles in genes for oil content can entails the possibility for new approaches to positively influence the oil content in rape seed (Osborn et al., 2007; Würschum et al., 2013; Jesske et al., 2013a). In this study, ... -
Geographic Indications as flagship products for sustainable landscape management in the European Union
(2023-12-04)This Ph.D. thesis addresses the broader topic of sustainable landscape management in European agriculture, with a specific focus on the potential of labeling as a tool contributing to achieving such a goal. The cumulative ... -
GlobalGAP Certification and International Trade Flows
(2015-01-29)GlobalGAP is an important private standard in the food sector. Our work consists of two essays. First essay investigates into geographic diffusion of GlobalGAP. We use a panel from 2008 to 2012 for 170 FAO member countries ... -
