The DEFRA Wheat Genetic Improvement Network 2

Lead Research Organisation: John Innes Centre
Department Name: Contracts Office

Abstract

This proposed LINK project aims to improve resource use efficiency and reduce lodging in wheat by developing reliable genetic markers and physiological understanding for genes that increase yield and affect height. It is estimated that reliable markers for two yield genes will enable breeders to increase yield by 10% without increasing the crop’s requirement for crop inputs. A physiological understanding of how the genes increase yield will ensure that crop management is tailored to achieve the greater yields as well as identifying the traits that must be improved to further increase yield. Genetic markers for five height genes (which are in addition to the known semi-dwarfing genes) will enable breeders to design crosses to minimise lodging risk and increase yield. Genetic markers for the height genes will also be used to predict which varieties will respond most to PGRs since some of the height genes have been shown to be more responsive to PGRs than others.

Description A collection of ancient bread wheat landraces, the Watkins collection, has been developed into a current germplasm resource. Genetically fixed lines have been developed from the 826 Watkins accessions. A characterisation of the genetic diversity of the population, firstly,
helped to asses the genetic diversity captured in the collection,
secondly, revealed a better idea about historic trends in wheat adaptation and, thirdly, enabled us to define a core collection of only 120 lines, capturing most of the genetic diversity.
10 of the lines, selected by showing interesting phenotypes, have been crossed to the elite wheat line 'Paragon', and segregating populations have been constructed. Initial assessment of field traits show that these populations will be resources for allele discovery.
We have developed libraries of near isogenic lines that can be used to study genetic effects of agronomic importance with high power. We have identified new QTL for drought tolerance and assembled panels to study lodging.
Exploitation Route Converting ancient landrace cultivars into resources for allele discovery for breeding.
Providing a core set of the collection for quicker screening by breeders.
Ten bi-parental mapping populations for allele discovery.
NIL libraries for the gene discovery.
Yield and drought QTL transferred to the DFW Breeders Toolkit.

Results and Impact The Breeders Toolkit (BTK) Committee considered nominations of new loci for inclusion in the Toolkit and BTK. Targets were selected for height reduction, increased dietary zinc in wheat grains (x2), and increased grain size. The Committee agreed the development of new segregating populations with WP3 of DFW based on exciting leads for aphid resistance.
