Breeding Witchhazel at The Holden Arboretum
Robert D. Marquard
Research formally began in 1991 with the addition of staff with advanced training in breeding, genetics, and plant physiology. The centerpiece of research is breeding woody ornamental plants. Complementary work involves: studies related to reproductive biology, genetic diversity, elucidation and utilization of biochemical markers, cytogenetics, propagation, and documentation of the inheritance of important traits.
By formal agreement, The Holden Arboretum acquired the germplasm accumulated by David G. Leach who has been a prodigious breeder of Rhododendron for over 50 years. Acquired in 1986, the plant collection is one of the best for cold-hardy Rhododendron germplasm. Staff were added in 1992 to help bolster research at this satellite research station of over 20 acres which is located within 30 miles of The Holden Arboretum.
A new building was built at The Holden Arboretum to provide research space and greenhouse/headhouse areas to meet the expanding needs
