For your amusement, some pics.
This one is from my Rodney F2: larger than the determinate line I grew out last year, smooth texture, sweet, great taste, but the shapes were gnarly. A very flat beef, very irregular ruffles. Indeterminate.
The parentage is:
Black Nipper F2 (Napoli Fiaschetto X Black Cherry) det X ZoSBe F1 (Zolotoe Serdtse X Black Early)
And the Rodney F1 was actually a pointy small heart shape.
As I understand it, some 'pointy' genes can prevent beef mis-shapes, even if not expressed as a pointy end. But this beef was so flat, there may be no 'pointy' here at all.
