For each plant accession, the origin, ploidy and degree of apomixis are indicated. Accessions marked with *were used for 454 sequencing, while those with °were used for Real-Time RT-qPCR. Apospory expressed as percentage was determined by flow cytometric screening of 48 single seeds. For details on the origin and composition of experimental populations please refer to [18].
