I have an apricot cultivar I'd like to identify. Plant was likely planted circa 2000. Only tag left on it was the one for the rootstock (citation). I'm in a fairly low chill environment (Valley Center, CA). I suspect the variety is Gold Kist (Off patent USPP 2826) an old patent apricot from Zaiger. First blossoms appear in mid February and the tree appears to be self-fertile. The fruit ripens in late May, has a red/orange dotty blush on the sun facing side, axial diameter of 1-3/4", 1-3/4" diameter in suture plane, with a deep suture from stem to blossom. The fairly large serrate leaves are ovate with an abruptly acute tip and measure 3-1/2" long by 3-1/2" wide, with petiole about 1-1/4" long. The stone has a sharp ridge on both sides (of the suture plane)
near the ventral edge. The stone is free, with some flesh adherence on
the ventral edge. Size of stone is 1" long by 1" wide by 1/2" thick. Any assistance with ID greatly appreciated.
