Rubus 'BT RASTWO'

Abstract

A new and distinct cultivar of Rubus plant named BT RASTWO is disclosed, characterized by very good tolerance to raspberry mite(T. uticae), yellow raspberry rust (P. rubi-idae) and resistant to frost damage. Plants produce many root suckers and very small, sparse spines. Fruit is broad, conical and shape, and colored light red, maintaining this light color during post-harvest. Plants fruit on both previous year's cane(mid-season) and current year's cane(mid to late season). The new variety is a Rubus, normally produced as an outdoor garden or container plant.

Claims
