DescriptionDuring the past few years, the Institute of Forest Genetics has received an increasing number of requests for pollen of various species of pine. Many of these requests have been fulfilled; others which stipulated arrival in time for specific crossing operations could not be fulfilled. The accompanying table is compiled to furnish cooperating pine breeders with the dates and places of pollen collection from various pine species and hybrids. This table will be revised and expanded to cover more species and additional genera as circumstances permit.
