This article identifies trends in cooperative research, a uthorship, and contribution of graduate students to research publications in agricultural sciences. Analysis of 4234 articles on genetics and breeding published in Crop Science during 34 yr was summarized relative to country, institution, authors, and plant species. The bulk of papers were authored by U.S. researchers, but 13.6% of the papers were contributed by international research centers and foreign researchers independently or as coauthors with U.S. researchers. The universities contributed double the proportion of papers compared with federal agencies (mainly USDA), and there has been a significant decrease in separate contribution but a significant increase in joint contribution by university and federal scientists. No evidence of an increasing trend in interinstitutional cooperative research between universities, private sector, and federal institutions was apparent. Over the years, there has been a significant increase in multiauthor papers. Thirty-nine percent of the papers had graduate students as the first authors. The proportion of articles with graduate students as the first authors increased while that of senior level scientists as the first authors decreased significantly, underscoring students' contribution to research during their education. The maximum number of papers were published on corn (Zea mays L.), followed by wheat (Triticum spp.) and soybean [Glycine max (L.) Merr.]. The proportions of articles on different crops showed significantly different trends. The information should be of interest to students, educators, scientists, and administrators as it presents a picture of their contribution to research publications in agricultural sciences.
