Wheat under environmental stress: experiments with 25 elite genotypes within the CORNET network.

German, Austrian and Hungarian wheat breeders and producers established a core set of 25 varieties (incl. 2 hybrid varieties) of winter wheat for testing and evaluation under different environments at 11 locations in the three countries in 2010. Different phenotypic data (heading date, grain yield, Hagberg falling number, wet gluten content, thousand kernel weight) were collected and evaluated. Hybrid variety Hyland showed high grain yield with good adaptability to humid conditions. Smallest changing of thousand kernel weights were observed for GK Petur, Hyland and Tacitus. Concerning quality traits Hyland was inferior to a lot of tested varieties. Hagberg falling number was well balanced when values were collected from 11 locations, but under extra Hungarian condition the differences were bigger. In Hungary highest values of falling number and wet gluten content were recorded for JB Asano, Element, Capo and GK Csongrad, and Exklusiv, Capo, Bitop and GK Bekes, respectively. The presented and discussed results will be integrated in wheat improvement and the second year of the CORNET research programme „Wheat Stress“.
