Dear Dr. Goodspeed:
I am a graduate student at Cornell University
with a major in plant breeding and a minor
in floriculture. These two fields of study are
combined in my thesis problem which is
with the genus Viburnum.
The problem will involve a cytological
chromosome study, pollen storage studies and
incompatibility studies of all species of Viburnum
available. This spring a series of interspecies
crosses and pollen storage studies were
undertaken. Root tips are now being used for
cytological chromosome studies.
At present the greatest problem is locating
sources of plant material. In some cases
flowering size plants have been planted at
Cornell University but this is not practical
for a large number of species. Cuttings,
small plants and seeds have been secured
of other species. However, when counting
chromosomes, I consider it best to use
