Genetic mapping and F2 progenies RAPD analysis of QTL's for height growth components of maritime pine (Pinus pinaster Ait.)
Early evaluation constitutes a challenge for forest tree breeding, but until now, only a few cases were successful (fungus or frost resistance). Early selection for height growth is much less conclusive. One possible cause to the lack of juvenile-mature correlation could be a change in the genetic control of the traits with time. Results have been published showing differential expression of genes during maturation. Therefore a way to early predict growth performances might be to accelerate ontogenetical ageing, so as to assess adult characters on young seedlings.
