Yes I hand pollinated it. I read somewhere that the self-fertile varieties have male part of the flower very close to the female part so the pollen will brush up against and dust the female part however the flower I got has a stigma high up while the anthers are so much lower down. Is it possible to have it pollinated despite of it ? or the pollen is just sterile and hand pollination is not going to work?
There is "self-pollinating" in that the stigma is very close to the anthers and it will probably brush up against enough anthers to set fruit with no human or animal interaction. I have had this with my S8 plant where I didn't touch the flower and it set fruit anyways.
There is "self-fertile" that, regardless of the structure of anther/stigma being close or far to each other, if you get pollen into the stigma, it will set fruit. If that happens by bees, bats, or by hand, it will set.
Then finally there is "self-infertile" where, regardless of if pollen enters the tube by hand or otherwise, it will not set a fruit and you need a different cultivar. If you have two self-infertile varieties and use one pollen on the other, it will set fruit, but I personally find I get way better fruit set using self fertile varieties of pollen. This may just be luck.
You won't know till you try, like I said.
