Tochigi Hemp General Population 1916 is a historical seed accession of Cannabis sativa that the United States Department of Agriculture received from Tochigi, Japan on 18 March 1916 and numbered plant introduction (PI) 42166.[1] No seed of the lot survives. The National Plant Germplasm System, whose database carries the department's introductions, says the accession "no longer exists and can not be requested".[1]
The lot
The department procured the seed from the Yokohama Nursery Company through Lyster H. Dewey of the Bureau of Plant Industry, and received it on 18 March 1916. Its printed inventory prints two notes on the hemp.[2]
The first, by S. Iida, calls it Tochigi hemp and says seed for sowing was scarce, because farmers grew no more than their own local needs, so that no large quantity could be had unless contracted for early in the season. Iida wrote that the most durable fishing nets in Japan were made from it, said to last three years while nets of hemp grown elsewhere lasted less than half as long, and that a net maker of Fujisawa who supplied nets all over the country used it exclusively. For fibre the seed was sown broadcast and close, so that the stalks grew slender and tall, and the stalks were cut green; plants grown for seed were spaced so that they branched freely, and left in the field until the seed ripened.[2]
The second note, by Dewey, calls Tochigi hemp the best fibre hemp in Japan, grown most extensively in the province of Tochigi, about 100 miles north of Yokohama, with slender tall stalks giving a fibre somewhat finer than the average Kentucky hemp. He judged it one of the most promising foreign hemps, but unlikely to do well in the United States until acclimatised by two or three generations of cultivation and selection.[2]
