Although in this case the tree that grows from the pip should not possess any genes not originally present in the parent, the two versions of each gene it carries (one from the male and one from the female gamete) will not always match up with the two versions in the parental apple. Hence, it should differ in some ways from the parent tree and is definitely not a clone.
    I am so glad you explained it in simple for the likes of me who would otherwise have been lost and bewildered....many thanks, I have read it from the first page and find it fascinating to learn a bit about the production of new types of apple, I might try a cross or two with the apples I have, you never know

    I've no idea if the crosses are genuine you'd hope so if nurseries are selling them as such

    A problem you may have is that those two types of apples flower at different times. Pitmaston isn't a group D and Pendu Plat is a group G, so its highly likely the pollen for one won't be available when the other flower is ready.

    I have both flowering the first time this year, at least in my garden this year court pendu plate isn't far behind the pitmaston but that could be a one off, due to soil or location. According to the national fruit collection info I can see a 4 day gap between 90% petal fall of pitmaston and 10% flowering for court pendu plat. So will have to take pollen from the last flowers of pitmaston and store it for use somehow. I've seen references to drying and keeping in the fridge so will have to investigate further
