The responses to salt stress in NFT (nutrient film) hydroponics of ‘Chinese Spring’ wheat and a number of its aneuploids involving the chromosomes of homoeologous group 5 were studied. This showed that the absence of chromosome 5D allowed plants to survive better than in the euploid condition. Much of this response could be related to the effects of Vrn3 , which conditions the spring habit of ‘Chinese Spring’. The ability to survive relatively high levels of stress was promoted by the group 5 homoeologue from Thinopyrum bessarabicum.
