Description
In recent years, a number of "new" elm taxa have been introduced into the United States from China.  Experimentation on resistance of these taxa to Resistance of several other taxa to insects and diseases is needed. Preliminary to such experimentation, it is desirable to know the chromosome numbers of these taxa. If any of these new Chinese introductions proved to be tetraploid, they might be more crossable with American elm. Therefore, chromosome counts were made on all of these taxa, none of which have been reported previously.
Abstract
diploid chromosome counts (2x = 2n = 28) are reported for the first time in 12 elm taxa newly introduced into the United States from China. These are Ulmus bergmanniana, U. bergmanniana var. lasiophylla, U. castaneifolia, U. changii, U. chenmoui, U. elongata, U. gaussenii, U. glaucescens, U. lamellosa, U. lanceaefolia, U. szechuanica, and U. taihang shanensis
