According to the preface the object

According to the preface the object of this book is to describe the business of taking basic seed from the plant breeder, multiplying it and ensuring that the farmer is supplied with high quality seed year after year. Since this is a long and involved process, the author has been wise enough to limit his objectives to dealing with general principles. He has also recognised that much of the information on seed technology is spread through a vast literature to which many people entering the industry are unlikely to have access. Therefore the book fills an important gap.In the first three chapters the author lays down the foundations for later chapters. Chapter 1 is devoted to discussing and defining seed quality whilst Chapter 2 describes the structure of the seed industry. Although some knowledge of botany is assumed, Chapter 3, quite rightly, is devoted to those aspects of seed biology, e.g. germination, which are of particular interest to the seed technologist. The next seven chapters are concerned with climatic and other requirements for seed production, agronomy, harvesting, processing and storage. They contain a good deal of valuable information drawn from the literature and the author's very wide experience. The remaining nine chapters deal with the principles of testing seed for those quality characteristics defined in the first chapter, and the principles and philosophy of seed certification, legislation and plant breeders' rights. Almost the entire technical basis for seed legislation and certification depends on the interpretation of results obtained by the examination of samples of seeds or plants. For this reason it is a pity that in Chapter 14 the author did not discuss more fully what results on samples mean in relation to the quality of the entire seed lot and show that the same principles apply to field inspection, control plots and laboratory tests. This shortcoming perhaps reflects the fact that the subject is possibly not well understood by seed technologists in general.The book contains several diagrams, all of which are extremely helpful, and a number of photographs which range from very good to very poor. Figure 14.4 is an example of the last category showing little except a stick sampler being used in a rather unconventional way. There is a very helpful glossary and a useful list of Latin names of the more important crops with common names in English, French, German and Arabic.One of the risks in writing a book dealing with general principles is that generalizations may be made without sufficient qualification so that the inexperienced reader may be misled by over-simplification. On occasions the author has fallen into this trap and become rather dogmatic in his attempts to generalize. In the section on testing for uniformity, the author's effort to explain the basis of the test in simple terms becomes so conceptually unsatisfactory that the reader may be left with doubts about the definition of uniformity. However, these criticisms are far outweighed by the good things in a book which newcomers to the industry and those with an indirect interest will find of considerable value.A. BOULD
