Since the foregoing overall coordinator's report, we have lost our enthusiastic barley geneticist and friend Tak Tsuchiya at the Colorado State University at Fort Collins, USA. He was there, besides all his duties and research programs, in charge of the Barley Main Stock Center. Since the establishment of the coordinator system in barley, Tak was the overall coordinator until the end of 1986. He was really eager to keep the linkage maps always up to date, and to encourage all the other coordinators of the linkage groups and collections to do their best in keepingup all the knowledge and writing reports. That was and is not an easy task. I want to take the opportunity to thank Tak in this report for all his efforts and his work for maintaining the World Collection of Barley Genetic Stocks and helping in publishing the Barley Genetics Newsletter yearly, as long as he was one of the editors. It was always a great pleasure meeting him at the first five International Barley Genetics Symposia, unfortunately he could not attend the 6th Symposium in Sweden in 1991 on account of his poor health already at that time. The discussions with Tak not only at the Symposia but also at Fort Collins were always of great interest and inspiration. I admired his great enthusiasm. Thank you, Tak, for all that you have done for barley cytogenetics. We barley researchers all miss Tak deeply.
No important changes of the coordinators have taken place since the last issue of BGN (Vol. 21). There is no coordinator for 'Trisomics and aneuploid stocks' at present. The Department of Agronomy at the Colorado State University at Fort Collins is responsible for the Genetic Stock Center until replacement for Tak Tsuchiya is employed. Seed requests can be made to Dr. Shaoke Wang, who also is the coordinator for chromosome 2, at the same department. An updated list of the coordinators with some changes of addresses and FAX numbers is available in the present issue.
Also this year only some coordinators' reports have been received. As has been especially called to attention in the last issues of BGN, it is important for barley geneticists to obtain current information from the coordinators. In BGN 21:11 the duties and responsibilities as reported in previous issues are again published to remind on the duties of the coordinators.
As many of you know Dr. Jens Jensen at Risø National Laboratory in Denmark (see coordinator for chromosome 5), has constructed a computer program for calculating the linkage values (cM) between many loci. One of our coordinators, Dr. T. Konishi, Japan, for chromosome 3, has learned this program for the Hewlett Packard Computer. In a letter to me as Overall Coordinator, he indicated that he and all the other coordinators should use theMS-DOS on 5 or 3.5 inch disk Operation System for calculating the linkage values. Dr. Konishi asked me to encourage this, and therefore I call on all coordinators to give me their opinion on this proposal.
