LA 3-3 & LA 3-33, also known as LA Early & Early St. Ann Satsumas were derived from seedlings of unknown parentage in the late '60's @ LSU.
Who knows...you might just come up with a new cultivar....kinda like the 'Croxton' Grapefruit.
I had 16 tangelo seedlings last yr, but somehow I let them die in this years drought. They were vigorous growers, sprouting to about 12" in no time it seemed.
Today I started 7 more & somewhere around 30 seeds from a tangerine that I suspect is 'Dancy'.
I will keep better watch on them this yr.
