A rapid method for early generation selection of dwarf genotypes in wheat

摘要: In the early generations of a breeding programme to incorporate successful Norin 10 semidwarfing genes into adapted tall or standard lines, bread and durum wheat breeder must be able recognise discard those lines that are not homozygous for dwarfing gene. A method which exploits gibberellin insensitive reaction carrying combined with ‘single seed descent’ technique is described in most unwanted genotypes may removed as F2 seedlings.
