Use of the Single Seed Descent Method in Breeding Safflower (Carthamus tinctoriusL.)

摘要

AbstractThe single seed descent (SSD) method of selection has been evaluated in safflower (Carthamus tinctoriusL.). The initial population of this study was a BC2F1from a cross between a well adapted and a high oil cultivar. Transgressive segregation for yield and oil content producing lines with considerably higher values than the better parent was observed in BC2F4and BC2F5generations. These results and the great saving of time and effort makes the SSD method a very desirable tool for safflower breeders.
