    Sixteen full-sib families from crosses between four fast-growing female and four fast-growing male clones of cottonwood (Populus deltoides Bartr.) were clonally evaluated for 1 year in a replicated field test. Seedling size had no effect on clonal performance. Approximately 70 percent of the genetic variance for height and 20 percent of that for survival were additive. The cloned families survived better and grew taller than 12 Stoneville select clones included for comparison, but this difference may have been due to repeated propagation of the select clones.
