a
Fruit shape according to the following scale: 1 = broader than long; 3 = as long as broad; 5 = slightly longer than broad; 7 = twice as long as broad; 9 = several times as long as broad.
b
Fruit size according to the following scale: 1 = very small; 3 = small; 5 = medium; 7 = large; 9 = very large.
c
Fruit predominant color when the fruit is physiologically immature according to the following scale: 1 = green; 3 = white; 5 = clear purple; 7 = purple; 9 = purple black.
d
Presence of PUC [pigment (anthocyanins) under calyx] dominant allele.
e
The fruit skin does not contain anthocyanins, and therefore, the PUC allele presence is unknown.
