Brief Guide for Authors

The Crop Journal is a bimonthly scientifi c journal co-sponsored by the Crop Science Society of China and the Institute of Crop Science， Chinese Academy of Agricultural Sciences and China Science Publishing & Media Group Ltd. Published by Elsevier and Science Press.

General Requirements

Contributions submitted to The Crop Journal must be original works of the author（s） that have not been previously published or simultaneously submitted to any other journals. The experiment related to crop yield should be conducted at least two locations or growing seasons with replications. All the results should be supported by appropriate statistical analyses.

Scopes

· Crop Germplasm Resources

· Crop Genetics， Genomics and Molecular Biology · Crop Breeding

· Plant Bioinformatics and Biomathematics

· Plant Protection and Pathology

· Crop Physiology and Crop Management （or Agronomy）

· Cropping System and Conservation Agriculture

· Grain Chemistry， Grain Storage and Processing

Editorial Review and Acceptance

Article acceptance for publication will be solely based on the quality and originality of the research and its signifi cance to science and technology. All manuscripts will be peer-reviewed by two or more anonymous reviewers， and the fi nal acceptance or rejection will be decided by the Editorial Board. Authors are encouraged to suggest three to fi ve qualifi ed reviewers. Final decisions on manuscripts will be made within three months of submission. Papers are usually published in chronological order of acceptance.

Preparation of Manuscripts

The manuscripts should be formatted in Microsoft Word. All pages should be numbered consecutively in the bottom right-hand corner，beginning with the title page.

Manuscripts in general should be organized in the following order：

· Title

· Name（s） of author（s）

· The institutions at which the work was carried out and their postal addresses

· Abstract （200—300 words） followed by 4—7 keywords

· Introduction

· Materials and Methods · Results

· Discussion

· Conclusions （optional）

· Acknowledgments

· References

Title should be clear， descriptive and specifi c. On the footnote of the fi rst page， E-mail addresses and full telephone numbers of the corresponding author and/or the fi rst author should be provided. Acknowledgments should contain fi nancial support to the research including the name of funding source and its granted number， the contribution of colleagues or institutions， etc.

All measurements must be in SI or SI-derived units.

Abbreviations should be used sparingly — only where they ease the reader's task by reducing repetition of long， technical terms. Initially spell the term in full， followed by an abbreviation in parentheses， and use the abbreviation thereafter.

Upon its fi rst use in the title， abstract， text and materials and methods，the common name of a crop should be followed by its scientifi c name（genus， species and authority） in parentheses. However， for well-known species， the scientifi c name may be omitted from the title.

The references should only include works that have been published or accepted for publication. Unpublished data and“personal communications” should not be listed in the references but may be mentioned in the text. References cited in the text should be numbered in the order of citation. All authors' names should be listed in the reference. If the works are not published in English， the actual language should be indicated in parentheses.

Tables and Figures

All tables and fi gures should be cited in the text， and numbered according to their sequence in the text. For the convenience of reviewers， the tables and fi gures should be arranged together with the main text document （see the sample）. Once the manuscript is accepted by the Editorial Board， high-resolution photographs should be provided for publication.

Other requirements for tables：

· Each Table should have a brief and self-explanatory title.

· Column headings should be brief， but suffi ciently explanatory.

Standard abbreviations of measurement units should be given in parentheses.

· Tables should be prepared with the table feature in word processor，instead of using tabs， spaces or graphics boxes.

· Extra space should be given between columns， instead of using vertical lines to separate columns.

· Any explanation essential to understand the table contents should be given as a footnote at the bottom of the table.

Other requirements for fi gures：

· Each fi gure should have a brief and self-explanatory title.

·Photographs and drawings for graphs and charts should be prepared with clear contrast of black and white.

· Line width or size and symbols should be suffi cient for clarity of fi gure contents.

·It is preferred for photographs， especially color ones to be grouped into one or more plates. The maximum length and width are 240 mm （not including the caption） and 170 mm， respectively for a full page.

· Legends should be concise and comprehensive， i.e. the plate and its legend must be understandable without reference to the text，including defi nitions/explanations of any symbols， abbreviations and units of measurements mentioned in the plate.

· Graphs and diagrams should be drawn with computer.
