Trial seeded at 25 lb/acre viable seed on Yolo clay loam soil at the Univ. of California Agronomy Farm, Davis, CA.                              
Entries followed by the same letter are not significantly different at the 10% probability level according to Fishers (protected) LSD.
FD = Fall Dormancy reported by seed companies.
Cuf 101 was included in this trial, but data was eliminated due to doubts about the source of the seed.
On 9/24 a partial harvest was taken and the total average  yield(mean) was 1.1 t/A.  The overall mean including the 5th cut is 7.44 t/A.
