On the basis of these findings, the Division of Forest Pathology since 1946, has made available to Federal and State agencies only one introduction of Chinese chestnut--P.I. 58602--for planting as forest trees. They were distributed in lots of 50 trees, and used to establish 1/4-acre demonstration forest plots. All are located on public-owned land on favorable forest sites where Asiatic chestnuts would be expected to do well. The underplanting-and-girdling method was recommended in the establishment of all the plots. Chinese chestnut P.I. 58602, because of its superiority in performance as a forest tree, is now also being used extensively at Beltsville, Maryland, in hybridizing work. Nearly all of the Japanese chestnut, Henry chinkapin, and Sequin chestnuts, as well as inferior hybrids in the climatic test plots during the past several years have died a natural death or have been destroyed. They have been replaced with Chinese chestnut (P.I. 58602) replants--thus gradually converting the climatic test plots into future Chinese chestnut "seed" plots of the very best Chinese chestnuts. During the spring of 1953 several nurserymen members of the Northern Nut Growers' Association furnished the Division of Forest Pathology a total of 2,600 Chinese chestnut seedlings for tests to determine their suitability for forest planting. These and 600 seedlings of Chinese chestnut P.I. 58602 are now being tested for performance, in randomized plots, on favorable forest sites in North Carolina, Ohio, and Illinois. Conclusions Of 28 Asiatic chestnuts, forest-tree chinkapins, and hybrids grown in 21 climatic test plots in the eastern United States under forest conditions, only certain Chinese and hybrid chestnuts show promise of becoming satisfactory timber-type trees. The best Chinese chestnut discovered thus far is P.I. 58602--a seed importation made by the U. S. Department of Agriculture in 1924, from Nanking, China. Foresters, as well as farm woodland owners, interested in growing Asiatic chestnuts as timber trees, should accept only planting stock that, through performance under forest conditions, is known to develop into straight, single-stemmed trees. PRESIDENT BEST: I think that Dr. Crane has his panel ready. DR. CRANE: Mr. President, before I start, I have a few slides here to illustrate a couple of points before we call the panel to the rostrum. (Several slides were shown illustrating sunscald injury to the Southwest side of high headed Chinese chestnut tree trunks.) DR. CRANE: On this panel, I want to get representatives from the various states. Mr. Wilson, from Georgia. Mr. Stoke from Virginia. Mr. Silvis from Ohio. Mr. Allaman from Pennsylvania. There is another good man down there who grows a lot of chestnuts, by the name of Gibbs.
