Intensification of the breeding process in wheat (T. aestivum L.) by using in vitro methods and characterization of the new developed genotypes

Using conventional breeding methods for obtaining the homozygous lines in segregated population takes a lot of time. This study presents the intensification achieved in the breeding process of wheat by application of embryo culture and dihaploidization on the material in intervarietal hybridization. Hybrids with high regeneration capacity at anther culture cultivation were obtained. For a considerably short period of 6-7 years large number of androgenic wheat lines were selected and analysed. Some of them combine valuable economic properties from both parental forms: higher yield and higher stem density. In the recent years these lines were used as initial breeding material for hybridization in Dobroudja Agricultural Institute. A candidate-variety was released, which exceeded both the initial parental forms and the standards by grain yield.
