Modern varieties, productivity, and sustainability: recent experience and emerging challenges
The contribution of modern varieties of the three major cereal crops.(rice, wheat, and maize) in the post-Green Revolution period, especially during the past decade or so, is reviewed in light of recent changes in the ...
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 ...
The contribution of genetic resources and diversity to wheat productivity: a case from the Punjab of Pakistan
This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and ...
A conceptual framework for valuing on-farm genetic resources
This paper proposes a preliminary conceptual framework designed to support strategic decisions about which crop populations-in a well-defined reference area within a crop's center of diversity-are suitable candidates for ...
Demand and supply of crop infraspecific diversity on farms: towards a policy framework for on-farm conservation
Interest is increasing worldwide in on-farm conservation as a component of a strategy to conserve crop genetic resources. On-farm conservation may require outside support to small-scale farmers in areas of crop domestication ...
The flowering of apomixis: from mechanisms to genetic engineering
(IRD; European Commission; CIMMYT, 2001)
Apomixis, the asexual reproduction of plants through seeds, has received increasing attention as technological advances have led to a rapid increase in knowledge about cellular biology, molecular genetics, and the mechanisms ...
