CABI Book Chapter

Quantitative genetics, genomics and plant breeding.

Book cover for Quantitative genetics, genomics and plant breeding.

Description

This book contains 20 chapters, divided into two sections: (i) Quantitative Genetics: Plant Breeding, Bioinformatics, Genome Editing and G×E Interaction (Chapters 2-12) and (ii) Intersection of Breeding, Genetics and Genomics: Crop Examples (Chapter 13-20). Section 1 emphasizes the application of genomics, and genome and epigenome editing techniques, in plant breeding, bioinformatics, quantitative...

Chapter 2 (Page no: 19)

Food and health: the role of plant breeding.

This chapter suggests that there is a contradiction between the need for diet diversity and crop uniformity, which is the main feature of industrial agriculture, and that there is also a contradiction between crop uniformity and the need to adapt crops to both short- and long-term climate change and to associated changes in the spectrum of pests and diseases. The role of plant breeding is to provide scientific support to cultivate diversity through an emphasis on specific spatial adaptation and wide temporal adaptation through decentralized selection, and with the use of evolutionary plant breeding methods. These methods have received official recognition in Europe for some important food crops, such as wheat, barley, oats and maize, which allows the seed of evolutionary populations to be legally commercialized. Reductionist approaches, such as those used to produce genetically modified organisms, gene editing and genomic selection, do not appear adequate to tackle the complexity of the challenges ahead. It is recommended that plant breeding should shift from 'cultivating uniformity' to 'cultivating diversity' for the benefit of human health.
