Welcome to the 4th Phase of WGIN (2018-2023)

Defra Wheat Genetic Improvement Network:

WGIN 4 - Improving the resilience, efficiency and stability of the wheat crop through genetics and targeted trait analysis

 

WGIN 4 has been funded by Defra until July 2023.

The strategy for WGIN4 including continuing as well as new projects is shown below:

A summary of WGIN3 achievements and the WGIN4 core project can be found here.

***Paragon Library***

WGIN has been part of an informal consortium developing NILs in the genetic background of the UK spring wheat Paragon. The collection, known as the Paragon Library, was developed at JIC and currently consists of around 350 lines.  The project involves crossing different combinations of genes, QTLs and mutations into the common background of Paragon and then studying the phenotypic effects.  NILs are currently available for multiple alleles of: Rht-D1, Rht-B1, Rht8, Lr19, 1BL.1RS, Yield (7B), Grain Size (5A, 7A) and more than 10 Heading Date QTL. Further lines will be added in the future.

The Paragon Library lines have been genotyped on the Axiom 35K Breeders' Array and data for about 300 lines is now available to download here and the figure to the right indicates the format of the data. Seed collected from the genotyped plants are now available for distribution on request and we hope they will eventually become available through the Germplasm Resources Unit (GRU) at JIC.

 

 

 

 

***High Density Genotyping of

18 WGIN AxC Near Isogenic Lines***

The WGIN AxC DH population has been exploited by many research groups around the world. NILs for WGIN QTLs have allowed us to show the value of the genes underlying these QTL for breeding and agriculture. Now Simon Griffiths’ group @ JIC has embarked upon the generation of a population where segments of the entire wheat genomes of Avalon or Cadenza are represented in individual lines of the opposite background. These will provide a unique resource for targeted screening of discrete chromosomal regions of interest through crosses to specific lines.
The initial stage of this process has been to genotype eighteen of these NILs, representing most of the identified QTLs, on the 820K Axiom Array at the University of Bristol Genomics Facility. All six detailed maps as well as information about them can be accessed here.

 

WGIN Background

The UK government is committed to more sustainable agriculture but this vision is facing an ever expanding range of environmental, energy and climate change challenges. Wheat is grown on a larger area and is more valuable than any other arable crop in the UK. Established in 2003, the Wheat Genetic Improvement Network (WGIN) Diagram of WGIN in the Wider Contextarose directly from a realisation in the early 2000s that over the preceding two decades there had been a widening disconnection between commercial plant breeding activities and publicly funded plant and crop research. The overall aim of WGIN is to generate pre-breeding material carrying novel traits for the UK breeding companies and to deliver accessible technologies, thereby ensuring the means are available to produce new,improved varieties. An integrated scientific 'core' which combines underpinning work on molecular markers, genetic and genomic research, together with novel trait identification, are being pursued to achieve this goal. The predicted wider impacts of the project can be viewed in the impact networks which were developed for each of the scientific objectives.

In all work which uses the DH Avalon x Cadenza population the following text must be cited: The population of doubled-haploid (DH) individuals, derived from F1 progeny of a cross between cvs Avalon and Cadenza, was developed by Clare Ellerbrook, Liz Sayers and the late Tony Worland (John Innes Centre), as part of a Defra funded project led by ADAS. The parents were originally chosen (to contrast for canopy architecture traits) by Steve Parker (CSL), Tony Worland and Darren Lovell (Rothamsted Research).
