1. The information in this Newsletter is of an informal nature to stimulate thought and to exchange ideas among barley geneticists. Before quoting any statements in the BGN, contact the contributor(s) involved with the following exception decided at the Second Interational Barley Genetics Symposium at Washington State University, Pullman, July 1969.

   "With regard to symbols and stock designations, the Newsletter (BGN) concerned with symbols, stock lists, and linkage maps may be cited without permission..."

2. Manuscripts should be written in English and should be brief.
3. Manuscripts should be organized and printed so that they can be photocopied for inclusion in the BGN.
4. Prepare all linkage maps and/or figures (photos and line drawings) on a separate sheet from the text. This enables the editors to incorporate these items in appropriate places in the BGN. The figures should be prepared in the same way as the manuscript for journals. Line drawings and linkage maps should be original, NOT a photocopy.
5. Typewritten original manuscript and one carbon or photocopy should be sent to the editor. The manuscript should be single spaced with a double space between paragraphs. The manuscript should be typed on white bond paper and follow the general format of previous Newsletters. Keep all typing within left and right hand margins of 3 cm, a top margin of 3 cm and a bottom margin of 2 cm. Do not number pages. Each paper should be prepared separately.
6. Manuscripts should be prepared carefully and proofread after typing because the editors do not have responsibility for errors or mistakes, obvious errors will be corrected by the editors.
7. A limited number of black and white photographs will be accepted. The photographs should be of good quality. The editorial committee reserves the right to make selection if it is necessary. In order to save cost of reproduction and get better quality, all photos will be reduced for reproduction in the Newsletter. Therefore, please prepare your original picture larger than the size to be printed.
8. Lined figures: If you would like to keep the original figures, please send a glossy photo of the original to the editor, but NOT a photocopy.
9. Please give your complete mailing address including the name of the country in all correspondence.
