Hexaploid Wheat Mapping Populations

Original Avalon x Cadenza Mapping Populations :

The original A x C double haploid mapping population (n=203 lines) generated in WGIN 1 is now being used for a wide range of phenotyping projects in the UK and also elsewhere.

Disclaimer for inclusion in publications: In all work which uses the Original 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).


Extended Avalon x Cadenza Mapping Population :

In total, 574 additional A x C double haploid lines are now available from RRes. These can be used to assist with the fine mapping of genes and QTLs controlling traits of interest segregating in this population. Funds were provided by the former director of RRes, Professor Ian Crute to increase the population size. Subsequently, WGIN 2 funds were used to multiply the newly generated A x C lines and to make small aliquots of seed for each line available to any interested UK plant scientist, wheat geneticist or breeder for research purposes. Contact – Dr Kostya Kanyuka and / or Professor Kim Hammond-Kosack.

The following wording shall be included in the acknowledgement: “The extension portion of the doubled-haploid Avalon x Cadenza wheat population, comprising 582 lines derived from F1 progenies of reciprocal crosses between the hexaploid wheat cultivars Avalon and Cadenza, was developed during the period 2007-2011 by Drs Kostya Kanyuka and Hai-Chun Jing at Rothamsted Research Ltd in collaboration with KWS Lochow GmbH, Germany, and co-funded by Prof. Ian Crute (the Rothamsted Research Director’s Fund) and Defra WGIN.”
