Konvalina, Petr; Moudry, Jan; Suchý, Karel; Capouchova, Ivana; Janovska, Dagmar.
Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties...
