Seed evaluation. (a) Gradient of seed development observed in the accessions under study. Only normally developed seeds (as indicated by the arrow) were considered to estimate the percentage of seeded berries. They possess a normal testa (consisting of outer and inner integument), endosperm and embryo.

The rightmost Corinto Nero berry contains a normal seed
