V. REPORT OF MAIZE GENETICS COOPERATION STOCK CENTER

During 1977 the Maize Genetics Cooperation received 143 requests for maize genetic stocks. There were 107 (75%) domestic and 36 (25%) foreign requests. Requests from geneticists constituted 56%, plant breeders 15%, plant physiologists 16%, and educational 13%. A total of 1407 seed packets were sent to fill these requests, 64% for domestic and 36% for foreign use. The distribution of seed packets by use was geneticists 74%, plant breeders 7%, plant physiologists 9%, and educational 10%.

Each year stocks are sent in by maize geneticists to become a part of the collection. The following have been received during the past several years and are on the stock list or will be placed there when adequate seed is available.
