Abstract: Raspberry wild species (Rubus paniculatus S.) of Garhwal Himalaya was selected to determine the pollen quality and quantity, pollination and fruit set under the hilly regions of Garhwal Himalaya. The raspberry produced 1,59,012 number of pollens per flower and exhibited maximum pollen grain size (length x width) of 35.87 x 17.73 µ in dry conditions and 35.44 µ x 16.52 µ in glycerine. The pollen viability was 73.33% and its longevity was extended up to 7th day. Pollens showed delayed germination (24 hours), the treatment T16 (25% Sucrose + 5ppm Gibberellic acid) showed maximum pollen germination 9.66%, 37.82% and 52.34% and pollen tube length of 88.05 µ, 99.18 µ and 135.22 µ, at 24, 48 and 78 hours after planting. Stigma receptivity was highest on the day of anthesis, pollination studies indicated that maximum fruit set was observed on natural pollination (cross pollination) than any other method of pollination. Interspecific pollination of Rubus paniculatus S. with Rubus niveus T. and Rubus macilentus C. revealed that Rubus paniculatus S. is good male parent with better fruit set, when it was used as female parent, did not set any fruits.
