The aim of the monographs is to foster effective intra- and interdisciplinary communication between geneticists, and plant and animal breeders. This is to be achieved by publishing authoritative up-to-date texts; concise, but at the same time comprehensive, monographs, and multiauthor volumes on theoretical and applied genetics. The following broad fields of genetics and breeding are within the scope of the series: Evolutionary genetics Developmental genetics Population genetics Biochemical genetics Ecological genetics Somatic cell genetics Biometrical genetics Agricultural genetics Cytogenetics Mutation breeding Radiation genetics Breeding methodology Acceptable subjects for the Monographs on Theoretical and Applied Genetics are basic and applied aspects of genetic variation; genetic resources; genetic exchange and reproduction; mutagenesis; genotype-environment interaction; gene structure, regulation, action, expression and interaction; chromosomal and extrachromosomal inheritance ofeconomic traits, and genetic models and simulations. September 1975 The Editors Preface Meiotic configurations are looked at from a special point of view in this book: the extraction from them of the maximal amount of quantitative information of genetic interest. Although this requires a certain understanding of their origin and consequences, much of what is known about chromosomes and their for­ mation into the special structures collected under the rather indiscriminate term I "configuration", is not considered relevant for this purpose, and simply neglected.

An introductory discussion of basic chromosome structure andfunction preceeds the main text on the application ofcytogenetic approaches to the analysis of the manipulationof both the genetic make-up and the genetic transmissionsystem of plant breeding material. Analysis using light andelectron microscopy, segregations and molecular techniques,yields information for assessing the material before andafter manipulation. Much attention is given to quantitativemethods. Manipulation not only involves the construction ofspecific genotypes, but also chromosomal transmissionsystems.Although analysis and manipulation in the somatic cycle areconsidered, the focus is on the generative cycle, withemphasis on analysis and subsequent segregation ofspecifically constructed material.The book is intended for plant breeders and other scientistsinterested in the analysis and manipulation of breedingmaterial at the chromosomal level. Comparisons withmolecular and cell biological approaches are made, and thepotential of the various methods is evaluated.
