FYI,
I had a white/yellow branch on my tree that did well for a year. It grew to about 3 feet with many smaller branches and it even had 2 fruits. I tried to grow the fruits (all light yellow skin from start to finish) but seeds never made it. After 1 year the large branch (3/8") eventually got sun burned looking and it dried up and died. I still get smaller growth of these white/yellow branches on my tree regularly and also one or so fruits on it. I would share photo but it was 5yrs ago when it had the large branches. Now its just a small 1 ft branch that is white/yellow and it turns brown like it was sunburned and dies off.
