Economic criteria for establishing plant breeding programs
A general model of annual costs and lagged annual returns from a plant breeding program is developed to estimate the threshold sizes of a crop industry at which different breeding programs could be economically justified, ...
Optimal search in ex situ collections of wheat genetic resources
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
CIMMYT World wheat facts and trends: supplement 1995 ongoing research at CIMMYT: understanding wheat genetic diversity and international flows of genetic resources
This supplement to the CIMJvfYT World Wheat Facts and Trends series summarizes objectives and preliminary results of a study of wheat genetic diversity and international flows of genetic resources (final results will appear ...
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 ...
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 ...
Cereal crop productivity in developing countries: past trends and future prospects
This paper synthesizes the evidence on cereal crop poductivity in developing countries over the past 30 years and looks at future prospects for productivity in growth. For more than three decades we have witnessed the ...
Nutritive and economic value of triticale as a feed grain for poultry
This study reviews evidence from various studies of the nutritional value of triticale (X. Triticosecale Wittmack) for poultry feed. The economic value of triticale as a major ingredient in poultry diets, substituting for ...
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 ...
Farmer plant breeding from a biological perspective: implications for collaborative plant breeding
Plant breeding by research has become increasingly isolated from the plant breeding of farmers. Collaborative plant breeding (CPB) offers the possibility of bringing these two plant breeding traditions together to increase ...
