Abstract
More than 20 years ago Scott Pauley (1949) designated the genus
Populus as the "guinea pig of forest-tree breeding. This designation is still appropriate as evidenced by the steady, almost overwhelming, stream of publications related to the genetics and breeding of poplars. A good indication of the scope and depth of genetic work with poplars can be found in the recent review of poplar breeding by Muhle Larsen (1970) and discussions of cottonwood genetics and breeding by Sckreiner (1971) and Farmer and Mohn (1970). These reviews cover a variety of research and breeding activities at widely dispersed locations and support the contention that our knowledge of poplar genetics is comparable with that available for any other group of forest trees. My assignment is to relate this knowledge to the "practical" breeding of cottonwood (
Populus deltoides) in the North-Central Region. While I will concentrate on eastern cottonwood, the biology of the genus
Populus requires consideration of the other species and hybrids commonly called poplars. Aspens will not be considered.
