Overview

Improvements in adaptation and maturity leading to greater yield are the most important criteria for the acceptance of a new crop cultivar, since yield improvement is one goal of virtually every crop breeding programme. Many such programmes have tended to concentrate on identifying the genetic traits responsible for higher yield and selecting each of them in the later stages of the breeding cycle. However, selection for yield per se is still the most effective method, since it is a combination of traits, operating within the limits of the system, which finally determines yield. This work presents a whole-system or holistic model for the improvement of adaptation, maturity and yield. Central to its thesis is recognition that competition between several components of the plant system, within a constant capacity, i.e. within the limitations of the system, determines yield and other cultivar characteristics. It goes on to describe how this can improve our understanding of plant systems. This understanding can then enhance the success of breeding trials by enabling a compromise to be reached between the different yield components which maximises performance under prevailing field conditions. Based principally on 25 years of research by the authors, the ideas presented in this book should be useful reading for crop physiologists and plant breeders.

Presenting a whole-system viewpoint for the improvement of adaptation, maturity, and yield in crops, this volume's thesis is that yield and other quantitative traits are determined by system-established changes among levels of all the components of the plant system, which itself functions at a near constant capacity dictated by the limits of the environment. Based on research conducted by the Wallace (plant breeding and biometry, emeritus, Cornell U.) and Yan (crop science, U. of Guelph, Canada), the text provides guidance to help plant breeders to maximize yield under prevailing field conditions by reaching a compromise between the levels of the system components. Suitable for professionals and advanced students in crop physiology and plant breeding. --SciTech Book News<br> Many scientists in today's agricultural research sector are aware of a trend toward funding reductive research projects at the expense of whole-systems research. This book carries the laudable premise that whole-system research should complement reductive research efforts toward the goal of improving agriculture. The book is divided into nine sections, including the relationship between photosynthate, partitioning and photoperiodic gene activity, the vernalization response and temperature, genotype x environment interactions, and breeding for adaption and yield. The greatest strength of this book is its suggestion that there is value to a systems perspective in crop biology. Through theoretical models and substantial field data, the authors do an excellent job persuading crop biologists to consider more realistic and holistic models in estimating important yield-related parameters in crop production. - I.L.Goldman, HortScience, Vol. 34(6), October 1999<br> [A] personal assessment of the relationship between crop physiology and plant breeding and a commentary on the way in which growth and yield has been researched. Workers involved in some aspects of crop research may find [this volume] a useful source of background information and references. The main readership will probably be protagonists in the debate about the contribution of physiology to plant breeding who will be interested in the thoughts of someone ... whose career spanned this era. --The Quarterly Review of Biology<br>
