*Total NN  = Means adjusted by nearest neighbor analysis.
Variety means are LSMEANS derived from nearest neighbor statistical analysis; therefore, season or multiple-year totals are not the arithmetic sum of individual cuts or years, respectively.
OK 200-3 is the syn 3 generation of a broad genetic germplasm.  C =  Seed was produced in Chickasha with poor bee activity; S = Seed was produced in Stillwater with good bee activity.  L = Large seed; M = Medium seed; S = small seed; and Reg =  The mix of seed sizes in the lot after reasonable cleaning.
