Plant breeding and nutrition 3 protein wheat and barley and in the possibilities of manipulating amino acid composition have encouraged breeders to proceed more positively with biochemical problems. In many ways this resurgence has been due to the wide publicity given to the potential of the opaque-z gene in maize, and the high-lysine story has stimulated expectancies which I consider are rathe...

Plant breeding by researchers 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 the usefulness of new crop varieties to farmers, especially small-scale farmers working in stress environments with limited external inputs. This paper presents a framewor...

In southern Mali and throughout the semiarid tropics, small-scale family farmers are faced with the challenge of producing adequate harvests in difficult biophysical and socioeconomic environments. Professional plant breeders have had much difficulty developing modern varieties that outperform farmers’ traditional varieties in these environments, in part because of an incomplete understanding o...

The current tools of enquiry into the structure and operation of the plant genome have provided us with an understanding of plant development and function far beyond the state of knowledge that we had previously. We know about key genetic controls repressing or stimulating the cascades of gene expression that move a plant through stages in its life cycle, facilitating the morphogenesis of veget...

PREMISE OF THE STUDY We developed microsatellites from Fothergilla ×intermedia to establish loci capable of distinguishing species and cultivars, and to assess genetic diversity for use by ornamental breeders and to transfer within Hamamelidaceae. METHODS AND RESULTS We sequenced a small insert genomic library enriched for microsatellites to develop 12 polymorphic microsatellite loci. The num...
