Have posted this before re: the genetics of multiflora in the lines they chose to investigate, at least. The donor parent of the multiflora trait of everything in this thread was Rose Quartz multiflora, mentioned in the paper below. I have seen variation in the level of "multifloraness" so would not surprise me if there are modifier genes in addition to environmental factors.
