Strawberry Gender Decided by Two Genes, Not One



"New research by an Agricultural Research Service (ARS) scientist and her cooperators found gender in strawberries is determined by two genes, not one as previously believed.

Strawberry plants possess one of three reproductive functions. Male plants bear flowers that produce pollen but cannot set fruit. Female plants produce fruit if their flowers are pollinated, but cannot produce their own pollen. Hermaphrodites contain both male and female functions that enable them to flower, self-pollinate and bear fruit. Neuters, which look like male strawberry plants, can also exist but do not posses reproductive functions." Stephanie Yao (ARS)
