En s'appuyant sur de nombreux exemples, cet ouvrage examine en détail les diverses techniques utilisées pour l'amélioration génétique des cheptels, telles que la sélection, les croisements et l'élevage en consanguinité. Après un bref rappel des fondements de la génétique et des principaux facteurs à prendre en considération, comme les effets du milieu d'élevage sur les animaux, les auteurs décrivent les méthodes en insistant sur leurs avantages et leurs inconvénients dans le contexte tropical et subtropical et sur la manière de les employer pour améliorer les caractères clés des animaux d'élevage. L'importance de conserver la diversité génétique des races locales d'animaux des régions chaudes est également soulignée. L'ouvrage aborde enfin les applications des progrès récents de la génomique à l'amélioration génétique, avec notamment le développement des marqueurs génétiques moléculaires au niveau de l'ADN. Cet ouvrage sera un outil précieux pour tous ceux agriculteurs, éleveurs, techniciens et conseillers agricoles -- dont les activités ou les intérêts touchent à la sélection et à l'amélioration des animaux et des productions animales dans les régions tropicales. Il servira également d'ouvrage de référence pour l'enseignement supérieur et les programmes de développement rural.

The Journal of Heredity covers organismal genetics in greater depth than ever before. Articles discuss gene action, regulation, and transmission in both plant and animal species, including the genetic aspects of botany, cytogenetics and evolution, zoology, and molecular and developmental biology.

Wheat, which is the second most important cereal crop in the world, is being grown in a wide range of climates over an area of about 228 945 thou sand ha with a production of about 535 842 MT in the world. Bread wheat (Triticum aestivum L. ) accounts for 80% of the wheat consumption, howe ver, it is attacked by a large number of pests and pathogens; rusts and smuts cause enormous damage to the crop and reduce the yield drastically in some areas. The major breeding objectives for wheat include grain yield, earliness, resistance to lodging and diseases, spikelet fertility, cold tolerance, leaf duration and net assimilation rate, fertilizer utilization, coleoptile length, nutritional value, organoleptic qualities, and the improvement of charac ters such as color and milling yield. The breeding of wheat by traditional methods has been practiced for centuries, however, it has only now come to a stage where these methods are insufficient to make any further breakthrough or to cope with the world's demand. Although numerous varieties are released every year around the world, they do not last long, and long-term objectives cannot be realized unless more genetic variability is generated. Moreover, the intro duction of exotic genetic stocks and their cultivation over large areas results in the depletion and loss of the native germplasm pool.
