Genetic diversity and population structure in South African, French and Argentinian angora goats from genome-wide snp data
(2016)The Angora goat populations in Argentina (AR), France (FR) and South Africa (SA) have been kept geographically and genetically distinct. Due to country-specific selection and breeding strategies, there is a need to ... -
Genetic diversity in a world germplasm collection of tall fescue
(2013)Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ... -
