Abstract

Insensitivity to the applied gibberellic acid, indicating the presence of Norin 10 dwarfing genes, was detected in 20 of 57 (35.1%) winter wheat varieties registered in the Czech Republic in 2002. Hybrid analyses in F2 generation showed a prevalent occurrence of Rht2 gene (in 14 varieties). Only 6 varieties were found to carry Rht1 gene. Among the recently developed Rht2 varieties, Clever possesses also a high bread-making quality which was not observed with the older materials. Rht2 varieties were found, on average, less winter-hardy, later in heading and more resistant to lodging than Rht1 varieties.
