摘要: Cultivated oat (Avena sativa L. and Avena byzantina Koch) is native to Turkey, a secondary center of diversity. Oat breeding has received less attention relative other cereals. In this work, the diversity landraces collected from different regions Turkey as well obtained gene banks was investigated using 3293 high quality SNP markers. Expected heterozygosity (Hs), observed (Ho), inbreeding coefficient (Fis), overall genetic (Ht) pool were 0.22, 0.01, 0.96, 0.38, respectively. The value differentiation (Fst) metric for structure 0.41 indicated that kinship more determinant population than geographical provenance. populations shared great proportion Clustering model-based STRUCTURE, principal coordinates (PCoA), neighbour-joining (NJ) algorithms mostly comparable except five discrepantl...
