The potato is one of the world’s most important food crops. It produces more nutritious food from less land in a shorter time than any other major crop. Therefore advances in the production of new potato varieties will greatly contribute to the world’s food supply. The book outlines strategies used in the breeding and testing of potato varieties. It considers prospects for varietal improvement using both traditional and new techniques, including genetic manipulation, tissue culture and protoplast fusion. Opportunities for breeding varieties suitable for propagation from true seed, of particular significance to the agricultural systems of developing countries, are also featured, together with an extensive and bibliography. The book is based on the proceedings of a joint meeting of EAPR and EUCARPIA at King’s College, Cambridge, December 1985. It contains contributions from many leading authorities in potato breeding and variety assessment throughout the world, and will interest post-graduate students in plant breeding, genetics and molecular biology, together with professionals engaged in potato research and the application of molecular biology to agriculture.
