can they reproduce the same kind if they are grown from the seed?
and how long will it take for it to reproduce fruit from a seed?
It's a gamble. I took seedlings from two sister seedlings, both from the same mother tree. One sister seedling had large teardrop shaped fruit that was sweet and acidic before all the way ripe and very sweet, little to no acid when ripe. The other sister seedling was medium size and round, with high sugar and high acid, just like I like them. It also had an apricot flavor and fruited 30 days after the other seedling.
I took 2 seedlings from the large fruited variety and 1 from the medium fruited variety due to only 2 being available, and the person who introduced me to the owner wanted one.
The seedling from the large fruited variety is just like it's mother. My daughter talked me out of the medium variety and it was just like it's mother. Her tree died the year after bearing.
Although my trees were almost copies of the mothers, the original seedling sister trees were very different.
Seedlings should bear fruit from 3 to 5 years. My trees were @2 years old when I got them and they fruited the following year
