Which breeding method requires the least record keeping?
Bulk method requires minimal documentation because seeds from entire F2-F5 populations are harvested together as bulk composite without labeling individual plants or rows. No pedigree tracking, no single plant numbering, and no progeny row maps are maintained during advancing generations; only final bulk lot identity is preserved with year and generation notation. Natural selection acts, and population evolves passively under environmental pressure. Labor for note-taking, tagging, and threshing individual plants is eliminated, and large populations exceeding 10,000 plants can be grown in high-
