A practical way to distinguish Beta orange from tangerine or apricot is that the Beta F1 cross to red or yellow fruit will be orange red, while the F1 cross of tangerine or apricot will be red.
For Beta vs tangerine, the segregating yellow cross rr should be easy to tell apart, since Beta is completely masked by rr ie the fruit is yellow, while yellow- tangerine rrtt is a pale orange color.
I guess I'll be watching for the colour of my Zolotoe Serdtse F1's, especially with Beta turning up in another Russian variety.
