Collection Name:Watkins Stabilised Collection of Tetraploid and Hexaploid Landrace WheatsCollection Image
Collection Description:

This entire collection of 1418 lines is made up of 1063 Hexaploid (Triticum aestivum – Sub collection Watkins Derived Hexaploid) and 356 Tetraploid (Triticum durum – sub collection Watkins Derived Tetraploid) landraces. All lines have undergone genetic stabilisation in the form of Single Seed Descent (SSD) development. Any notable differences (phenotypic and genotypic) within hexaploid genotypes have resulted in sub accessions being generated from the original noted by prefix 1-4. 

Initial genetic hexaploid characterisation is published (Wingen et al, 2014, doi: 1007/s00122-01402344-5) with 41 SSR markers. Further 35k genotyping is also published for 804 hexaploid accessions (Wingfield et al, 2017, doi: 10.1111/pbi. 12757). Genotyping data is available from CerealsDB.

A core set of 119 Hexaploid lines have been defined (Wingen et al 2014, available on SeedStor as a Compiled Accession List) which captures a sizeable amount of the total diversity available across the entire set. A set of 90 of these lines have been used to create the Nested Association Mapping (NAM) collections using elite common parent Paragon. Further details of which can found at and seed of this can be ordered from the DFW NAM panel in SeedStor 

The tetraploid collection was genotyped using 35K Axiom® array (data available upon request A core set of 50 tetraploid lines (available on SeedStor as a Compiled Accession List) was generated using Core Hunter 3 ( The development of biparental mapping populations is under construction.

Seed is generated and supplied as a precise genetic stock from hand harvested bagged ears of glasshouse grown plants or as field grown, machine combined stocks.

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

Many of the core set accessions of the "Watkins Stabilised Collection of Hexaploid Landrace Wheats" were used in a nested association mapping (NAM) panel of 90 bi-parental populations with the elite wheat cultivar "Paragon". These are available from SeedStor
