Table 4 Evaluation of the detected intra- and interchromosomal linkage disequilibrium (LD). LD analysis was performed for the whole set of 953 barley accessions and a subset of 207 European 2-rowed spring barley accessions. The number of common loci pairs in LD is shown in bold.

From: Analysis of molecular diversity, population structure and linkage disequilibrium in a worldwide survey of cultivated barley germplasm (Hordeum vulgare L.)
