Breeding line selection based on multiple traits

W Yan, J Frégeau‐Reid - Crop Science, 2008 - Wiley Online Library
Breeding line selection, either for potential varieties or for useful parents, must be based on
multiple breeding objectives (or traits). Varieties cannot have any major defects, while
parents must have outstanding levels in at least one trait. Due to undesirable associations
among breeding objectives, it is difficult to accomplish both tasks (variety selection and
parent selection) through a single selection strategy. Additional complication results when a
program is breeding for different end‐uses such that both high and low levels of a trait are …
