Genetic progress and inbreeding rate in complex breeding programmes – Applications to sport horses and laying hens
(2013-03-22)The main focus of this thesis is the optimization of breeding programmes. On the one hand a new method to account for the average inbreeding in the design of breeding programmes has been developed. On the other hand two ... -
Genetic variants of EPO and EPOR influence cognitive core features of schizophrenia
(2011-03-18)Introduction: Erythropoietin (Epo), a hematopoietic growth factor, has long been observed to improve cognition but this effect was attributed to the increase in hemoglobin levels. Even after ... -
Genetic variation and inheritance of phytosterol and oil content in winter oilseed rape (Brassica napus L.)
(2015-01-28)Phytosterols are natural constituents of vegetable oils that are among the dietary option to reduce serum LDL-cholesterol. Oilseed rape (Brassica napus L.) is ranked the second richest source of phytosterols among vegetable ... -
Genetic variation and inheritance of phytosterol content in <i>Brassica napus L.</i>
(2007-09-13)Improving oil and protein quality for food and feed purposes is considered as an important goal in rapeseed (Brassica napus L.) breeding programmes. Seeds of oilseed rape have been shown ... -
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 ... -
Genetic variation and inheritance of seed fiber components in oilseed rape (Brassica napus L.)
(2025-01-13)Oilseed rape (Brassica napus L.) is a major oil crop and a valuable protein source for animal and human nutrition. The oil-extracted meal of oilseed rape has a high protein content and a well-balanced amino acid composition. ... -
Genetic variation and inheritance of seed fibre content in winter oilseed rape (Brassica napus L.)
(2014-06-13)The meal from oilseed rape is a valuable product as substitution for soybean meal in animal diets due to its high protein content and its excellent balanced composition of essential amino acids. However, the presence of ... -
Genetic Variation for Nitrogen Efficiency in Oilseed rape (Brassica napus L.)
(2003-09-15)Oilseed rape is produced today under high N fertiliser application. However, the crop is known to be having a low N efficiency mainly due to low translocation into the seed during the ... -
Genetic variation of the genus <i>Shorea</i> (Dipterocarpaceae) in Indonesia
(2006-03-27)This dissertation is composed of three parts using the AFLP marker technique to characterize genetic variation of Indonesian dipterocarps, a dominant tree family in Asian tropical rainforests: ... -
Genetical Aspects of Bone Stability in Laying Hens Differing in Phylogeny and Performance Level
(2022-01-21)Skeletal disorders in laying hens is one of the most serious problems facing the egg production industry and is gaining increasing attention due to changes in husbandry systems and overall increased public concern about ... -
Genetics of microspore embryogenesis in Intervarietal Substitution Lines of rapeseed (Brassica napus L.)
(2024-07-23)Microspore embryogenesis, a tissue culture-based propagation technology, is of great importance in rapeseed breeding to produce doubled haploids (DHs) in shortest time. Brassicas have become model plant species to study ... -
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 ... -
