Collection Name:Watkins Stabilised Collection of Hexaploid Landrace WheatsCollection Image
Collection Description:This is a genetically stabilised collection of 830 hexaploid wheat accessions, which was developed from the "Watkins Historic Collection of Landrace Wheats " (by two generations of single seed descendants (SSDs). In 25 percent of the cases the phenotypes of second generation SSD plants from the same accession showed noticeable phenotypic segregation. In those cases, two streams (sister lines) were carried forward. The resulting 1060 accessions were genetically characterised using 41 SSR markers (Wingen et al., 2014, doi: 10.1007/s00122-014-2344-5). This genetic analysis revealed a high level of genetic diversity and showed that accessions can be assigned to nine ancestral populations. The genetic characterisation also showed that sister lines differ on average in a third of their SSR marker alleles. 804 accessions of the "Watkins Stabilised Collection of Hexaploid Landrace Wheats" have been genotyped using the 35k Axiom Wheat Genotyping Breeder Array (Winfield et al, 2017, doi: 10.1111/pbi.12757). Genotypes are available from CerealsDB (http://www.cerealsdb.uk.net/cerealgenomics). A core set of accessions has been defined (Wingen et al 2014), which captures the majority of the genetic diversity present, these are the first 119 lines listed. To further facilitate access to the genetic diversity of the Watkins Collection, many of the core set accessions were used in a nested association mapping (NAM) panel of 90 bi-parental populations with the elite wheat cultivar "Paragon". More information on the NAM panel can be found at http://wisplandracepillar.jic.ac.uk/results_resources.htm.
