Populus trichocarpa, a fast-growing tree species, grown in plantations as a complementary source of renewable raw material for various industries. P. tricocarpa can be vegetatively propagated which is an advantage in breeding since you could easily make many plants from one single individual. Individuals of P. trichocarpa (A - H) are crossed according to the crossing scheme below. Offspring from each cross are grown in a field experiment to get more breeding related information. After two years of growth, height of the tallest shoot is measured on each plant. Below you have the result of this measurement (in cm) with the mean height of each family indicated. a) Estimate the general combining ability (GCA) for all parents in the mating scheme below. b) What conclusions can you draw from these GCA estimates? c) Estimate specific combining ability (SCA) for the cross between female C and male F. d) Why should you (as a Populus breeder) have knowledge about the SCA?

Transcribed Image Text:Populus trichocarpa, a fast-growing tree species, grown in plantations as a
complementary source of renewable raw material for various industries. P. tricocarpa can
be vegetatively propagated which is an advantage in breeding since you could easily
make many plants from one single individual.
Individuals of P. trichocarpa (A - H) are crossed according to the crossing scheme below.
Offspring from each cross are grown in a field experiment to get more breeding related
information. After two years of growth, height of the tallest shoot is measured on each
plant. Below you have the result of this measurement (in cm) with the mean height of
each family indicated.
a) Estimate the general combining ability (GCA) for all parents in the mating scheme
below.
b) What conclusions can you draw from these GCA estimates?
c) Estimate specific combining ability (SCA) for the cross between female C and
male F.
d) Why should you (as a Populusbreeder) have knowledge about the SCA?
