Abstract
Abstract Efforts to bring back the chestnut as a forest-tree species have had only limited success. Of the hundreds of surviving American chestnut trees tested for resistance to the blight fungus Endothia parasitica, few have even the slightest degree of resistance. Substitutes have been more successful. Of Asiatic trees imported, several show promise. Tree breeding programs have had some successes. Of thousands of hybrids produced, about 3 percent exhibit to some degree blight resistance, rapid growth, and forest-tree form. Treatments with colchicine and irradiation are being tried to produce a mutant of American chestnut that has blight resistance.
