Comparison of Pedigree and Bulk Methods of Conventional Plant Breeding

Year	Pedigree Method	Bulk Method	Haploid Method
1	Cross Parents	Same as in pedigree method	cross parents
2	Grow F1		Grow F1; derive haploids and DHs (anther culture)
3	Grow F2 (2000-10000 seeds space planted); select for qualitative traits; harvest seed on single plant basis		doubled haploids (DHs) are used for initial trials
4-5	Grow F3, F4 (plant to progeny rows from selected plants); select rows plants	Harvest seed in bulk in F2-F5; no selection; only natural selection	Trials to verify performance; release of variety
6	Grow F5; initial trial 3-4 rows of each plant progeny); compare and select
7-9	F6-F8; trials to verify performance	space planting; select single plants; plant to progenies; yield trials
10	Final trial and release of variety	Final trial and release of variety
