Seed Parents In

Today I finished bringing the 2013 seeds parents into the greenhouse.  I will be using at least this many additional seed parents outdoors, however, I like to bring the ones that I will be mainly focusing on into the greenhouse.

The seedlings are continuing to sprout at a very rapid pace.  Today there were 13,392.  You may be wondering, "did he really count them all?"  Well not quite.  For the early germinators, I just counted the seedlings that had clearly sprouted since I last counted them.  However, for the later germinating groups I did count them all.  I will probably only do one more count - and that will only be of seedling lots that still haven't germinated well.  So why count them at all?  Each year I like to evaluate germination rates especially of seedlings that set hips well that I haven't used for breeding yet.  Since germination rates are sometimes 0% even when hundreds of seeds are planted of a particular variety, I do not want to waste time doing crosses on those roses.

The rose forest is beginning to grow.

  1. Do you try to stratificate two times or not at once? I'm not expert about roses but some species needs two stratification like Rosa canina if I have good inforamtion.
