From June 19-21, 18 trainees were trained in “Breeding for complex traits”.
Complex traits are generally traits that are expensive and/or difficult to record on
a large scale. Mostly these traits are multi-factorial and many biological processes
are lying underneath.
The trainees were first taught on the biology of methane emissions by Pekka Huhtanen
from SLU in Umeå. In the afternoon, Eileen Wall (SRUC, Edinburgh, UK) covered all
aspects of the selection index theory. In the evening there was an excursion to the fish
ladder, with some hopes to see the salmon jump. Unfortunately, we didn’t see the
salmon, but the explanation of the fish ladder was very interesting.
On Tuesday morning, Britt Berglund (SLU, Uppsala, Sweden) explained the opportunities
for breeding schemes for complex traits. She was followed by Jan Lassen (Viking Genetics,
Denmark) by showing the importance for industry to be able to breed for complex traits.
What traits are important for the industry, and what do they need from scientists in
order to move on?
On the last day the trainees worked on their own breeding programme, incorporating all
the aspects they had learned the previous days. The Training School finished with a
visit to the experimental farm where many complex traits are recorded.
