DFW Breeders' Diversity Toolkit
The aim of Designing Future Wheat (DFW) Programme is to deliver new useful genetic variation and knowledge to breeding.
Pre-breeding germplasm is developed and handled in a collaboration between DFW WP3 and the
Germplasm Resource Unit (GRU).
The new pre-breeding germplasm will include near isogenic lines (NILs) from
wheat diversity sources. NILs or equivalent material are assessed for the trait of interest within DFW.
Particularly promising germplasm will be multiplied and trialed in multi-site trials at commercial breeders
and scientific institutions as an annually changing Breeders' Diversity Toolkit (BTK) series.
The DFW BTK series carries on from the WISP Breeders' Diversity Toolkit (see below).
It is one major result of DFW, taking output from WP1 and WP2 forward to pre-breeding.
DFW Breeders' Diversity Toolkit Selection Committee
Decisions on QTL or genomic regions and germplasm are made by the Breeders Toolkit Annual Selection Committee Meeting. It decides on the content of the DFW NIL back-crossing pipeline (NIL sets, putative candidates for a BTK) and on the final selection of the annual BTK lines. The following representatives sit on the the committee:
QTL or genomic regions and germplasm can be nominated by any researcher within DFW to the chair of the committee by submitting a completed form on germplasm, trait of interest, markers etc. using the following form: BTK germplasm nomination form. The committee meets in February (first time in 2018) to decide on the larger back-crossing pipeline and in September to decide on the next BTK.
The BTK will be tested in multi-site trials at different breeding companies and institutions,

WISP Breeders' Toolkit (BTK) 2016-2017
The WISP Breeders' Diversity Toolkit, based on landrace cultivar diversity, is the result of joint resource development and analysis carried out at the John Innes Centre, Rothamsted Research, University of Bristol, and University of Nottingham. The genotypes in the current selection (as of January 2015) are derived from F4 SSD, progeny of crosses between the UK spring wheat variety 'Paragon' and AE Watkins landrace cultivars[1] kept at the John Innes Centre.
The main prebreeding output of the WISP landrace pillar is Near Isogenic Lines in the genetic background of Paragon. They were developed through two marker assisted backcrosses which started off with a RIL from the respective Paragon x Watkins landrace population. So the NILs carrying Watkins alleles will carry ~ 87% Paragon background. This is the first cohort of landrace derived NILs from WISP. This is why the emphasis is on height and heading as the QTL analysis to inform the choices were based on data from the first season of WISP at JIC. However, the first year of assessment of the NILs (14-15) gave us some encouragement that landrace alleles might carry agronomic benefit and we encourage you to assess these materials.
WISP Breeders' Diversity Toolkit 2016
Loci covered are on chromosomes 3A and 5A for ear emergence, and 7B for height.
The set is a subset of the 2015 Toolkit, lines for which the last field trial suggested that the QTL loci confer a yield benefit upon Paragon.
