Current Genotypic Data

Flapjack Format including QTL Data: Impromalt Data to 2014

The .flapjack files require the Flapjack graphical genotyping software which can be downloaded here.

The latest file contains 713 spring and winter barley lines that have been placed on the UK National List up to February 2014. They have been genotyped with 5675 iSelect SNPs that are polymorphic and have a minor allele frequency of >10% in either the springs and/or the winter barley groups. QTL information is provided for a range of phenotypic characters that have been collected as part of the UK National and Recommended List trialling system. Each QTL is significant with a -log10(P) value of at least 3 and the effects are referenced with respect to the spring barley Overture. QTL were detected for 36 spring barley phenotypes and 36 winter barley phenotypes with some being unique to the crop type.

The map is based on a merging of the IBSC, POPSEQ, and Zooper Zeeper maps resulting in the location of 7480 iSelect SNPs. This is just a best fit of the data so treat the exact ordering with some caution and it may be that some QTL coalesce when we have the location of all SNPs on the latest genome assembly.
