Breeding without breeding

Genetics Research, 2009
SummaryAn innovative approach to tree breeding called ‘breeding without breeding’ (BWB) is presented. The method, as applied on the material in hand, allows the capture of 75–85% of the genetic response to selection attained through conventional programmes without the need to do any controlled pollination and simplified or possibly no experimental ...

Conservation priorities for Ethiopian sheep breeds combining threat status, breed merits and contributions to genetic diversity [PDF]

, 2008
Prioritizing livestock breeds for conservation needs to incorporate both genetic and non-genetic aspects important for the survival of the breeds. Here, we apply a maximum-utility-strategy to prioritize 14 traditional Ethiopian sheep breeds based on ...
