Generationswechsel in kleinen Familienbetrieben als biographische Arbeit
(2007-07-24)More than 90% of all German companies are family businesses and in one-fifth of them an alternation of generations is taking place at present. In spite of varied career possibilities in ... -
Genetic analyses of the resistance of faba beans (Vicia faba) to the fungus Ascochyta fabae
(2022-07-26)Climate warming is a huge challenge for agronomists, although it may offer opportunities to new crops and new types of old crops, such as winter types in so far spring-sown species. In Germany, mostly spring faba beans ... -
Genetic Analysis of Dog Congenital Deafness and Herding Behavior
(2021-10-05)Strong artificial selections of canine morphological and behavioral traits lead to the formation of more than 400 modern dog (Canis familiaris, CFA) breeds within the past 300 years. Most dog breeds are derived from small ... -
Genetic Analysis of Heterosis in Rapeseed (B. napus L.) by QTL Mapping
(2007-09-12)Heterosis, or hybrid vigour, refers to the phenomenon that progeny of diverse inbred lines exhibit greater biomass, speed of development and fertility than the better of the two parents or ... -
Genetic analysis of saturated fatty acid composition and other seed quality traits in rapeseed (Brassica napus L.)
(2024-06-20)Genetic improvement of seed oil content and oil quality had been the main objective of rapeseed (Brassica napus L.) breeders until recently, when interest in improving rapeseed meal (RSM) as a secondary trait increased. ... -
Genetic differentiation within and between populations under selection – studies on diverse chicken populations and the Göttingen Minipig
(2013-05-03)In this thesis different aspects of the use of high density markers in the genetic characterisation and analysis of farm and experimental animal populations are addressed. First, a general introduction and an overview over ... -
Genetic diversity based on SSR markers, heterosis and yield performance of Brassica rapa for biomass production
(2008-02-14)Biogas production has recently become of major interest in Europe. The substrate mainly used is biomass from energy crops and 2% of agricultural land in Germany is presently used for the cultivation of energy crops. ... -
Genetic diversity in sesame (Sesamum indicum L.): molecular markers, metabolic profiles and effect of plant extracts on soil-borne pathogenic fungi
(2007-06-26)Sesame (Sesamum indicum L.) is an important crop in tropical and subtropical areas. Sesame seed is traditionally used for direct consumption, because of its high nutritional value (50 % oil ... -
Genetic evaluation of longevity in dairy cattle - A new model for an old trait
(2017-11-23)Longevity is an important trait in dairy cows, reflecting the overall functionality of a cow. The aim of this thesis was the development of a new model for the routine genetic evaluation of longevity in German Holsteins. ... -
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. ... -
Genetic parameters for productive and reproductive traits of sows in multiplier farms
(2001-08-22)Reproductive performance is one of the important components of sow productivity, and is recognised as a key factor affecting the efficiency and economy of the pig industry. In particular, ... -
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 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 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 ... -
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 ... -
