Aims and objectives of Plant Breeding Plant breeding is an art and science, which tells us ways and means to change the genetic architecture of plants so as to attain a particular objective. Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable.

The first edition of Principles of Plant Breeding (1960), by R. W. Allard, professor of genetics and of agronomy and range science, was a book used worldwide as a university textbook as well as a guide for plant breeders. In this second edition, the author has edited the book, including additional data about the evolution of plant populations during domestication and cultivation; these evolutionary changes play an important role in understanding the principles and methods of plant breeding and improvement.

The book has three parts: Introductory Topics, Biological Foundations of Plant Breeding, and Modern Plant Breeding. Part I, Introductory Topics, has five chapters: Darwinian Evolution, Origins of Agriculture, Evolution During Domestication, Mating System of Plants, and Overview of Plant Breeding. The author devotes the first two chapters of the book to the central ideas of Charles Darwin's Origin of Species (1859), to the Darwinian evolutionary changes which occur during cultivation, and to the origins of agriculture. In the third chapter, he describes evolution during domestication, discussing when the first selection pressure was applied to wild plants and what brings them to cultivation. In chapter 4, the author focuses on mating and reproductive systems, which are important in determining the methods of breeding for three main groups of plants (self-pollinated plants, cross-pollinated plants, and vegetatively reproducing plants). Chapter 5 surveys the major effects of mating systems, genetic linkage, and epistasis for the improvement of cultivated plants—factors that are so important for selection and successful plant breeding.
Part II, Biological Foundations of Plant Breeding, consists of six chapters: Heredity and Environment, Genetic Consequences of Hybridization, Inheritance of Continuously Varying Characters: Biometrical Genetics, Evolution During Cultivation, Marker-Assisted Analyses of Adaptedness in Nature, and Marker-Assisted Dissection of Adaptedness in Cultivation. In the second part, the author discusses the genetic principles of Mendelian inheritance on which plant breeding is based (chapter 6). Further, he covers Mendelian segregation and recombination (chapter 7), continuous variation, and biometrical methods (chapter 8). Improving adaptedness during the evolution of cultivated corn during long-term experiments lasting more than one hundred generations is discussed in chapter 9. Genetic markers in relation to adaptedness in nature and in the cultivation of plants are discussed in chapters 10 and 11.
Part III, Modern Plant Breeding, consists of the following chapters: Reproductive System and Breeding Plants, Breeding Self-Pollinated Plants, Breeding Hybrid Varieties of Outcrossing Plants, Breeding Clonal Propagated Plants, Breeding Hybrid Varieties of Selfing Plants and Plants that are Clonally Propagated in Nature, and Plant Breeding for Low Input Agriculture. In chapter 12, the author again stresses the importance of mating/reproductive systems for breeding plants of particular species. In chapters 13–15, he describes methods in the modern breeding of self-pollinated plants, outcrossing plants, and clonal propagated plants. Breeding hybrid varieties of self-propagated plants that are clonally propagated in nature is described in chapter 16. Breeding for low-input agriculture is a new agenda in agricultural production and plant breeding because 1.4 billion people worldwide still depend on subsistence agriculture, which is 60% of total global agriculture, producing only 15–20% of the world's food.

In conclusion, it may be said that the second edition of the Principles of Plant Breeding includes many aspects of biological sciences and technology that are extremely important in developing more useful plants for today's world. The glossary and indexes at the end of the book are useful and this book is highly recommended for students, as well as for plant breeding professionals all over the world.

Book review Principles of Plant Breeding – Second Edition. Edited by Robert W. Allard, John Wiley & Sons Ltd. (ISBN-0-4710-2309-4); Price: £ 45.50 There cannot be many books about plant breeding that make for captivating reading, but Allard’s second edition of the Principles of Plant Breeding is undoubtedly one of them. This edition is eminently more readable than the first. The chapters are separated into three parts, rather than the original, more cumbersome nine, with a greater emphasis being placed on the historical aspects and theories of plant breeding. Practical aspects of breeding are covered in part 3, but not before the foundations for understanding these principles have been elegantly laid out in parts 1 and 2. Allard begins, at the very beginning, with the creation of the universe and the evolution of life. Darwin’s theories of selection emphasize the importance of nature, as well as man, as plant ‘breeder’, with Allards’ own experiments on the evolution of adaptiveness being elegantly presented to illustrate this theme. Two seemingly opposite schools of thought are described in some depth; Mendel’s discovery of the orderliness of inheritance and Galton’s biometrical descriptors of continuous traits, which were united through the work of Johannsen and East who determined that a number of Mendelian units of inheritance could result in a continuous phenotype. Several basic genetic principles are covered mathematically (e.g. outcrossing rates, heritability estimates, coefficients of inbreeding and fitness, random mating in small populations, genetic advance under selection) but these do not weigh down the text too heavily. Many of the figures and photographs of the first edition have been removed so that illustrations are few and far between. Two illustrations that remain are my old favorites and great teaching aids describing the smoothing influence of environment and gene
number on the distributions of discontinuous traits. Two large parts of the original book; on hostpathogen genetics and polyploidy, have been removed. The chapters on the genetics of host-pathogen interactions and breeding for disease resistance were comprehensive, but needed updating in light of more recent developments in this area. As this subject is sufficiently covered in numerous alternative texts, their removal is probably appropriate. It is disappointing however that the chapters on polyploidy, still an important area of plant breeding, were removed. Remarkable though this book is, it is written by one person and it does show. Allard’s own work on co-adapted gene complexes are emphasised and re-iterated throughout much of the book. The reliance on barley (for inbreeders) and maize (for outbreeders) to describe the progress that has been made through breeding means that equally impressive examples from other crop systems are ignored (for example, the work on tomato carried out by Allard’s coworkers within the same university). Obligate outbreeding crop systems are covered in very little depth. Surprisingly, apomixis, currently an important area of research, is dismissed as being of no relevance to plant breeding (despite a later advocation to fixing heterosis through clonal propagation). Unexpectedly, this new edition does not address the impact of molecular markers and biotechnology on plant breeding. Molecular markers are covered to some extent but mainly to describe experiments on environmentally adapted gene complexes. Mapping and QTL mapping are addressed with the description of a single paper on QTL interactions and the relationship between heterozygosity and heterosis. A host of complementary papers are not discussed, including the excellent work of Stuber et al. on QTL mapping and heterosis. A passing comment on the use of

gene cloning to manufacture pharmaceuticals in clonally propagated plants is the only acknowledgment given to biotechnology. The book ends with a disappointing new chapter on breeding for low input systems. Allard merely melds together some information on G×E interactions and evolution of adaptiveness (again) to conclude that breeding for developing countries involves breeding for broadly adapted germplasm. Many obvious points concerning breeding for low input systems are not made, for example, the low relevance of the previously described dwarf sorghum varieties to subsistence farming is not commented on.

Ultimately, one cannot expect such a slim volume to cover every aspect of breeding in depth and still remain an enjoyable read; those looking for a comprehensive and broadbased volume on all practical aspects of breeding should look elsewhere.
