Clones vs. massal selection

The standard

The reasoned selection decision names the aim it serves: yield security and phytosanitary control on one side, genetic breadth and site adaptation on the other.

Criteria

  • The aim of propagation is named, not left to chance
  • Clonal choice buys uniformity with genetic narrowing
  • Massal selection buys diversity with higher phytosanitary risk
  • Both paths remain selection, not new breeding

Distinction

Selection ≠ breeding: selection preserves existing genetics, breeding creates new varieties. The reasoned selection decision chooses between uniformity and diversity, not between old and new.
