Lupins as Crop Plants: Biology, Production and Utilization. Edited by J.S. GLADSTONES, C. ATKINS, and J. HAMBLIN. CAB International, 198 Madison Avenue, New York, NY 10016-4341. 1998. Hardcover, 465 p., $135.00. ISBN 0-85199-224-2.

Lupins as Crop Plants is the first comprehensive text on lupin as a crop. The book serves as a comprehensive reference and as a synthesis of most of the available literature on lupin. Although lupin species have been cultivated for thousands of years, only recently has this crop received the attention that it deserves. John Hamblin, in his preface, explains that the domestication of the three new species from one genus, lupin, in "such a short time is probably unique in the history of agriculture. What is even more remarkable is the fact that a further four species from the genus have since been domesticated or at least have all the domestication genes available and will be fully domesticated before the end of the millennium." This text makes it very clear that much of the information in the book is derived from Australian experience. John Gladstones released the first variety, `Uniwhite', in 1967 and production reached 1.4 million tonnes in 1995. This growth in production and interest is clearly the result of the great efforts that the Australians made in breeding, selection, and agronomy and other associated sciences. This text is organized into 15 chapters, and can be classified into four broad areas: genetics, selection, and breeding; physiology; agronomy and pathology; and economics and utilization.

The first chapter, written by J.S. Gladstones, provides a detailed discussion of the distribution, origin, taxonomy, history, and importance of Lupinus. This chapter serves as a good introduction to lupin domestication because there are a number of species that are agronomically important, and they have a distribution in the new world as well as important populations within the Mediterranean and elsewhere. The present natural distribution and habitats provide us with clues for behavioral traits observed within modern cultivars and provide insight to where important collections can be made.

The second chapter continues with a review of the genetic resources of Lupinus. This chapter focuses on the genetic stocks including mutants, selections, transgenic and interspecific types that are critical for lupin domestication and improvement. One of the things that makes studying lupins so interesting is that sweet cultivated lupins were "fully domesticated during the past sixty years and are genetically very close to their wild and land-race parents." The chapter details the major collections and provides knowledge of the boundary conditions for specie adaptation. Included are data relating soil pH, altitude, rainfall, phenological data, alkaloid levels, yield components, and ranges for the species.

To further the discussion of lupin genetic resources, a chapter by C.A. Atkins et al. provides a concise and detailed review of the cytogenetics of Lupinus. Topics include a comparison of genomes; attempts at interspecific hybridization, successes and failures; and strategies for overcoming barriers to interspecific hybridization. The chapter includes a summary of recent attempts using genetic transformation technology and recovery of transgenic plants. Attempts to confer resistance to virus and altering hormonal balance for yield improvement are documented.

W.A Cowling, C. Huyghe, and W. Swiecicki follow this chapter with a discussion of Lupin breeding. The authors provide the historical background of lupin breeding during the early parts of the 20th century starting with von Sengbusch's initial work with L. luteus, L. angustifolius, and his selections of low-alkaloid strains from L. albus during the early 1930s. They provide a description of the domestication and barriers to domestication associated with development of lupin as a crop plant. The chapter moves from a historical discussion to what they term the "era of modern lupin breeding" and acknowledge the importance of wild lupins as well as natural and induced mutants in modern lupin breeding. A major barrier to development of lupin in many regions with cooler climates was the lack of germplasm with restricted branching or determinacy. They document the development of determinate lines in L. albus and its importance during the 1980s to the present. This is an important discussion because indeterminate development and thermosensitivity has been, until recently, one of the most limiting factors to lupin development. Another important topic is the issue of alkaloid content in the seed and in the plant. Sweet types are important for use as human or animal feeds. High alkaloid types are of great interest for pharmacological uses. These authors note that sweet types and high-alkaloid types have two independent uses, and that this has lead to a problem for breeding, agronomy, and utilization because sweet types can cross with high alkaloid types and revert to high alkaloid wild types. The industry producing sweet types is obviously very interested in keeping their germplasm sweet.

The next several chapters make up the physiological discussion of lupin in this text, beginning with lupin nutrition by Longnecker, Brennan, and Robson. This discussion deals with a traditional agronomic approach to lupin growth, dealing with the anatomy of roots, the importance of root hairs, lateral roots and depth of rooting, and documents the phenomenon of cluster or proteoid roots. Proteoid roots have attracted many research studies because of their importance in phosphorous nutrition. The chapter outlines the importance of various minerals on lupin growth and development and seed quality.

A chapter is devoted to nodulation, nitrogen fixation, and nitrogen balance of lupin and discusses the unique symbiosis of Lupinus-Bradyrhizobium sp. (Lupinus). The information documents the conditions that set this symbiosis apart from other legume-rhizobium symbioses, considering edaphic stresses such as soil acidity. The chapter provides mechanistic detail about key events in the symbiosis. The information detailed provides the student or researcher an excellent overview of lupin nitrogen nutrition and symbiosis.

In the chapter, Transport Physiology and Partitioning, Pate et al. take a mechanistic approach in looking at source-sink relations of C and N and include sections on growth regulators and transport. The review approaches transport phenomena as a larger issue than lupin. (Lupin happens to be an ideal model system for transport study.)

Miles Dracup et al., discuss lupin responses to abiotic stresses such as drought, and include topics of tissue water relations, water deficits, leaf gas exchange rates, and the impact of water deficits on dry matter partitioning and yield. Among the stresses they discuss include temperature, soil alkalinity, mineral deficiencies and toxicities, salinity, soil acidity, waterlogging, and compaction.

The next several chapters in the book are devoted toward discussions of diseases and pests and agronomy and farming systems. In the chapter on diseases and pests by M.W. Sweetingham et al., all the major diseases of lupin are discussed which include leaf spots, obligate parasites, vascular wilts, stem and pod blights, root diseases, and viral diseases. The other major limiting factor hindering lupin domestication is disease, in particular susceptibility to anthracnose [Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. in Penz].

In the chapter focused on agronomy and farming systems development, morphology of the plant, interactions with the environment and phenology and plant improvement are related to productivity. The rest of the chapter is devoted to a more conventional discussion of the agronomy of lupin and its role as a rotational crop.

Finally, the last several chapters deal with the utilization and implementation of lupin, an assessment of their value in a farming system, and their food uses. D.S. Petterson provides a history of the composition and food uses of lupins and discusses the historical use of lupin in the Mediterranean and Andean regions and provides a discussion of the fatty acid, carbohydrate and mineral content, and anti-nutritional factors associated with lupin. This is a very detailed chapter, which includes sections on major components of the seed and relates it to their attributes for human consumption.

The use of lupin seeds for ruminant and non-ruminant livestock and fish is detailed. A major topic related to lupin utilization is that of the presence of toxins and the occurrence of lupinosis. Jeremy Allen provides a very detailed discussion of lupin toxins and the occurrence of lupinosis, a mycotoxicosis "caused by the ingestion of toxins known as phomopsins produced by the fungus Diaporthe toxica".

The final chapter focuses on marketing and trade. To date, the success of lupin is primarily an Australian story. This chapter provides an overview of the success of the development of the Australian sweet lupin industry as well as the development of the global market for lupin.

This book is highly recommended for any professional or graduate student interested in lupin. The editors have compiled and synthesized the current state of knowledge on the genus Lupinus. The book serves as probably the only comprehensive reference on this genus. Its outlook is international and documents the domestication of Lupinus species and provides information regarding agronomy, physiology and other factors affecting production based upon the Australian experience of developing, producing, and marketing this crop to the point of having economic significance. This book serves as a case study for students interested in crop domestication and development. J.S. Pate acknowledged in his chapter that there is an "embarrassingly large proportion of parochially oriented references, which may be viewed as idiosyncratic of Western Australian conditions." Many of the authors are indeed Australian, but when looking at the domestication of this crop and the development of a lupin industry, the real success story has been the Australian story.
