This book is based on the presentations given by a multidisciplinary group of scientists at an international symposium on the Evaluation and Utilization of Genetic Resources in Wheat Improvement, held at the International Center for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria. The symposium attracted 58 participants from five continents and was sponsored jointly by ICARDA and the University of Tuscia in Viterbo, Italy. Plant breeders now have a greater range of genetic diversity available for utilization than in the past. However, the usefulness of collections depends on the estent to which they are gepgraphically and ecologically representative and on the presence of genes which are not commonly found in conventional breeding germplasm. Various reasons have been given for the prevailing reluctante of breeders to make more use od this germplasm. There is a tendency for breeders to use materials with which they are familiar and which are already adañted to their particular environment, as opposed to using alien germplasm, which requires carriying out a laborious programme of pre-adaptation trials and the evaluation of germplasm for desirable traits. To enable researchers to identify potentoally useful accessions, information on collections needs to be more readily available.
