Understanding global trends in the use of wheat diversity and international flows of wheat genetic resources
This paper discusses the centers of origin and diversity for bread wheat; sketches historical patterns in the sources and use of wheat genetic resources in modern plant breeding; identifies and compares indicators of genetic ...
Genetic change in farmer-recycled maize seed: a review of the evidence
This paper summarizes what is known about farm-level maize seed management practices and reviews the theoretical and empirical evidence regarding the relationship between farmers’ seed recycling practices and the genetic ...
Sources of productivity growth in wheat: A review of recent performance and medium-to long-term prospects
Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years ...
Continuous economic analysis of crop response to fertilizer in on-farm research
This paper proposes a method for building general models based on continuous analysis of data from on-farm research (OFR) in order to derive recommendations for farmers. The data requirements are not excessive for practitioners ...
Institutionalizing the role of the economist in national agricultural research institutes
The evolution of the role of economists in agricultural research institutes (ARIs) over the past two decades is described. A framework for determining relevant research activities for economists in ARIs is presented, with ...
Crop management research and extension: The products and their impact on productivity
This study presents a methodology (in five steps) for assessing the impact of information and technologies generated by a crop management research (CMR) program. The methodology is demonstrated by estimating the return to ...
Research on triticale (X. Triticosecale Wittmack), the product of a cross between wheat and rye, actually began at CIMMYT a year before the Center was formally established in 1966. The program's original objective was to ...
Organization and performance of national maize seed industries: a new institutionalist perspective
This paper proposes a conceptual framework for analyzing the organization and performance of national maize seed industries. The authors begin by reviewing what several leading economic paradigms have to say about the ...
Quantitative analysis of data from participatory methods in plant breeding
Although participatory plant breeding (PPB) is gaining greater acceptance worldwide, the techniques needed to analyze the data from participatory methodologies in the context of plant breeding are still not well known or ...
