CABI Book Chapter

Crop stress management and global climate change.

Book cover for Crop stress management and global climate change.

Description

The second in a three-part series on climatic change, this book addresses the challenges of the foreseen climate change for agriculture from a multidisciplinary point of view. The initial chapter discusses the global changes that gave rise to the beginning of agriculture. The rest of the book is subdivided in two major parts: first, towards an understanding of the present and future challenges imp...

Chapter 7 (Page no: 105)

Breeding to improve grain yield in water-limited environments: the CSIRO experience with wheat.

In this chapter, the traits of wheat (including xylem vessel diameter of seminal roots, tiller inhibition, early seedling vigour, gibberellic acid-responsive dwarfing genes, extended vegetative growth, root growth and architecture, waxiness/glaucousness, transpiration efficiency, stem carbohydrate storage and remobilization and leaf-rolling) studied by CSIRO (Commonwealth Scientific and Industrial Research Organisation) are described, together with an outline of the environments where they are likely to be most effective, ways to select for them, results of validation, proof-of-concept tests and whether they are currently incorporated in breeding programmes. These traits are shown in a table, together with the components of the Passioura identity (Water use × Water-use efficiency × Harvest index) that are likely to be increased so that grain yield may be increased.
