TABLE 2.

Summary of per stage parameters and annual operational costs for the ‘medium’ Grid genomic selection breeding program (Grid-GS).

Year	Stage	Reps	h2	Grid-GS
1	Cross			40 × 90
2	DH	1	0.10	3,600
3	Grid	1	0.10	900/250,000*
4	SIA1	16	0.67	50*
5	SIA2	32	0.80	8*
			Cost (United States $)	493,800

Cost is set at approximately United States $500K. Reps, the effective number of replications (i.e., locations); h², narrow-sense heritability; DH, the doubled haploid stage; Grid, the Grid stage; SIA 1 and 2, the specific intercropping ability stages 1 and 2; *number of specific intercrop combinations.
