Alexander Silva, Margaret Worthington, Michael A. Hardigan, and Nahla V. Bassil. This success story discusses how scientists mapped the primocane-fruiting (annual flowering) gene in blackberry and developed reliable diagnostic markers that breeding programs can use to identify seedlings with this valuable trait. Improved analysis of the genome sequence for the Rubus argutus ‘Hillquist’ enabled identification of different genetic variants associated with primocane fruiting.
