Rye-wheat introgression & alien translocations

 

Rolf Schlegel has put together an extensive list of all wheat varieties containing the 1RS.1BL translocation and recently updated his website at

http://www.rye-gene-map.de/rye-introgression

Recent surveys show that more than 45 % of breeding material may contain those translocations (Zhou et al. 2007) or 55% of CIMMYT bread wheat germplasm. This translocation has been deemed so important that it has been incorporated into >60 wheat varieties that occupy >50% of all developing country wheat area, almost 40 million hectares.

Illustration shows a wheat breeding line (2n = 6x + 2 = 44) with a pair of chromosome arms from rye (labeled green with genomic DNA from rye) translocated onto a wheat chromosome (1BL.1RS) and an additional chromosome pair from the wild species Thinopyrum bessarabicum (labeled red with genomic T. bessarabicum DNA) from Trude Schwarzacher (e.g. Practical In Situ Hybridization, 2000, BIOS publishers).
