The Mysore raspberry, Rubus albescens Roxb. (synonym, Rubus lasiocarpus Smith) has recently been introduced into Puerto Rico. The experimental plantings of this raspberry have been established at the University of Puerto Rico, Agricultural Experiment Substation, at Castañer, situated in the middle of the central-western mountainous region of the Island. Based on the study of the experimental plantings for the past 4 years the general characteristics, propagation, culture, use of fruits, etc., of the Mysore raspberry have been briefly presented in this paper. The Mysore raspberry has grown fairly well at Castañer. If the cultural practices are employed carefully it produces well-flavored, sweet, and juicy berries over a period of several months during the year. The fruits are good for eating fresh and also for making jellies, jams, etc. It is a promising new fruit for small-scale production in the central-western mountainous region of Puerto Rico.
