End Date: Aug 31, 2015
Accessions will be identified according to the latest understanding of elm taxonomy, collecting herbarium specimens at different times of the year to allow coding of characters of the flowers, fruit, and leaves, and winter buds. Genetic diversity and phylogenetic relationships will be analyzed by DNA analysis of appropriate nuclear and chloroplast regions, evaluating new markers as necessary. Genome size and ploidy of representative accessions will be investigated using flow cytometry and (if necessary) chromosome counts.
