Abstract:

Intraspecific crosses were made using five different pollen mixes on the same Pseudostuga menziesii seed tree. At germination, it was found that average cotyledon numbers of the progenies could be used to verify several hybrid parentages even though average numbers differed by one cotyledon or less.
