Since 1971, international aid for agricultural research has been shaped by an unusual and ambitious partnership: an organization founded as an ad hoc consortium of national governments, foreign aid offices, philanthropies, United Nations agencies, and international financial institutions that is known today as CGIAR. At its founding, the Consultative Group on International Agricultural Research was tasked with fostering scientific research that would help “developing nations … increase and improve the quality of their agricultural output.” Representative of an era of broad multilateral cooperation, and reliant on complex international funding networks, CGIAR assumed the profoundly localized mission of reshaping farmers and fields across diverse cultural, economic, and environmental contexts. The tensions arising as researchers and institutions navigated the demands and expectations of these distinct scales form the crux of CGIAR history. They have affected the changing disciplinary orientations of research centers, the ecologies prioritized in breeding, the expectations for intellectual property management, and even the words used to describe crops.

The circulation of data ranked high among the objectives adopted by CGIAR at its founding in 1971. This chapter considers how agricultural experts attempted to realize a desired “full exchange of information” among scientists working at geographically distant sites, in different languages and cultural contexts, with different organisms and research interests from the 1970s to the early 2000s. The chapter focuses on the historical development of “crop descriptors,” today defined as providing an “international format and a universally understood language for plant genetic resources data.” Developers of descriptors aspire to agree on traits and terms that will allow users from diverse institutions and backgrounds to contribute to and extract information from an integrated data infrastructure. The chapter examines crop descriptors as a critical component of CGIAR’s earliest efforts to create “system-wide” research tools and agendas, emphasizing the scientific and political agendas that shaped this top-down systematizing work, finding that it provided an opportunity for CGIAR to instantiate and consolidate its central position in a web of international development initiatives.

This essay uses a recent acquisition by the Whipple, a seed herbarium called ‘The Origin of Seeds Source Indicators’, to explore the curious history of the global trade in commercial seed stocks in the early twentieth century. Little was known about this seed collection when the Whipple Museum acquired it. There was no place or date of creation, no record of its ownership, and, most pressingly, no knowledge of the uses for which it had been intended. Investigating this enigmatic object exposed the intriguing link between weeds, seeds, and commercial forage stocks in an increasingly international seed market, as well as the many challenges of using laboratory instrumentation to try and manage the tumult of international agricultural exchange.
