Abstract Rubus geoides, a native herb of Patagonia,
has fruit with a bitter-sweet taste that can be eaten fresh or in marmalades
and jams. The aim of this work was to develop a protocol for the in vitro
propagation of R. geoides. The proposed protocol allowed a multiplication
rate of 1:3.5 to be obtained at day 63 with Murashige & Skoog (MS) medium
with 1.10 µM 6-benzylaminopurine added. Most (80%) of the shoots
rooted on MS with half-strength macronutrient salts and 2.46 µM
indol-3-butyric acid added and an initial period of darkness of 7 days. The
root systems were of suitable quality to begin the acclimatisation stage.
These results are the first for R. geoides from adult plants obtained in
the field.
