I would suspect that "yatsubusa" black pine seeds are actually highly variable and probably won't produce the tight backbudding that yatsubusa types of plants produce. "Yatsubusa" roughly means "dwarf" and nothing more. The term covers a wide variety of cultivars that have short, tight growth. More often than not, those cultivars, especially the pine types, are grown from "witches brooms" on older plants. They are not propagated with seeds, but made from cuttings. The original cutting is cloned thousands of times to produce seedlings.
Just like specialized Japanese maple cultivars--or any other kind of genetically manipulated plant cultivar--the seeds will be high unreliable in reproducing the unique charateristics of the mother plant. In other words--don't count on getting a "Yatsubusa" variety from a seed produced by such a cultivar. The odds are overwhelmingly against you coming up with the exact same genetic variation as the parent. |

But the thread as taken a turn. I was asked if I received suc seeds. I said no, but Ic confirmed having seeds of Japanese black pine that produce pines with shorter needles. But you are right, exact genetic transmission can be done, but is really something random. Random like any other species propagated by seeds. For example, if I sow 100 seeds of trident maple, ill probably get 70% germination rate. From these 70%, Ill have some that will grow slowly, long internode, big leaves, but Ill also get a few that will grow fast, have short internodes and small leaves. By having seeds that come from a plant with specific characteristics, you get more chance of having these genetics reproduce in the seeds. Funny, but the same principle apply to human, if you have parents with big nose, you have more chance of having a big nose. Regards, Patrick
