Abstract
Publisher Summary This chapter outlines the improvements of agricultural crops by genetic engineering. Improving the quality and yield of crops through breeding has been for long time a straightforward concept. Until 1983, this goal could only be achieved by sexual recombination followed by selection or, to a lesser degree, by random or induced mutations. Recent progress in molecular and cellular biology has greatly extended the range of sources from which, new traits can be obtained for crop improvement. Using molecular techniques, based on recombinant DNA technology, it has become possible to transfer genes from any organism into plants without sexual crossing. This technology should represent a major progress in man's efforts toward increasing the production and utility of agricultural crops. Molecular biologists have made equally dramatic progress in the identification and improvement of genes encoding valuable agronomic traits. Transfer of these genes into plants leads to the creation of crops with properties, which were unachievable by classical breeding approaches.
