Summary The Chinese wheat variety 'CN0004', described to carry the new GA insensitive dwarfing gene Rht21 on chromosome 2AL was used for test crosses with the GA sensitive variety 'Bersee' and its isogenic lines 'Bersee iso Rht-Blb' {Rhtl) and 'Bersee iso Rht-Dlb' (Rht2). Performing the GA seedlings test in F2 it could be demonstrated that 'CN0004' is carrying two genes for GA insensitivity allelic to Rht-Bl and Rht-Dl which are located on...
