What does self-fertile mean in blackberry varieties?

• A. Plants require cross-pollination
• B. Plants produce fruit year-round
• C. Plants produce sterile fruit
• D. Plants have both male and female parts and do not require pollenization

Answer: (D)

Self-fertile means a blackberry variety can set fruit without pollen from another plant. This happens because the flowers have both male and female reproductive parts, allowing fertilization to occur on their own. So you can get fruit from a single plant without cross-pollination, though having another plant nearby can still boost yield or fruit size. It doesn’t mean fruit will appear year-round or that the fruit is sterile.
