• Adverse genetic correlations can curtail breeding progress as, for example, a negative genetic correlation between growth and wood density would make it more difficult to select concurrently for improvement in both traits. (Costa e Silva et al., 2008)
• The review effectively curtailed the breeding activities in the public sector, especially of the major crops. (Acquaah, 2012)
• While hybrids are less utilized in more temperate zones, eucalypt hybridization programs involving controlled crossing were undertaken early in countries such as Russia and France, but hybrid development was curtailed by extreme frosts. (Julian Evans John A. Youngquist, 2004)
