Origin & Breeding History: 'Fukukasumi' (experimental designation TA-1) was developed by the breeder, Yoshihiko Uematsu, Takano Foods Co. Ltd., Ibaraki, Japan. The new variety is the result of a controlled cross made in 1997 at Gunma field of Takano Foods Co., Ltd., in Maebashi, Gunma-pref., Japan between the female parent 'Suzuhime' and the male parent 'Suzumari'. The F1 seed was harvested in November 1997 and sown in April 1998. The F2 seed was harvested in July 1998 and sown in August 1998. Using the pedigree breeding method, F2 plant selections were made in August-November 1998. A repeated selection of each generation continued until the F11 generation with 'TA-1' being selected in 2003. Selection criteria included early maturity, small seed size, high yield, lodging resistance and processing suitability. Agronomic performance testing occurred in Illinois, USA from 2002-2005.
Tests & Trials: Trials were conducted during the summers of 2006 and 2007 in St. Thomas, Ontario. In 2006, plots consisted of 2 rows, each 5 meters in length. There were 2 replicates arranged in an RCB design. In 2007, plots consisted of 3 rows, each 4 meters in length. There were 2 replicates arranged in an RCB design.
