Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations
(Journal article; Peer reviewed, 2017)The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters ... -
Genetic yield gains of winter wheat in Germany over more than 100 years (1895-2007) under contrasting fertilizer applications
(Journal article; Peer reviewed, 2018-09-27)For highly productive regions such as Germany, the increase of wheat grain yields observed throughout the 20th century is largely attributed to the progress in crop breeding and agronomic management. However, several studies ... -
Genetics and welfare in organic poultry production: A discussion on the suitability of available breeds and hybrids
(Bioforsk rapport;9(10) 2014, Research report, 2014-01-31)Organic production of eggs, broilers and turkey is regulated by international and national regulations and differs from conventional production. Breeds and hybrids selected for conventional production are also used in ... -
Genetisk variasjon i ask
(NIBIO POP;3(5) 2017, Others, 2017-02)De norske askeskogene er en nordlig utløper av større askeskoger i Europa som spredte seg nordover etter siste istid. Vi har undersøkt genetisk variasjon i ask (Fraxinus excelsior) og funnet at asken i Norge fulgte en ... -
