Molecular breeding for improving waterlogging tolerance in wheat.

Abstract

This chapter summarizes the current understanding of the response of wheat to waterlogging stress, the genetic control of uptake and transport of macro- and micronutrients, and the QTLs and genes associated with tolerance mechanisms. Potential targets for molecular breeding through marker-assisted selection and the potential for genomic selection are discussed in order to provide a better understanding of the biology and genes underlying soil waterlogging tolerance, as well as clarity and direction for breeders for future molecular breeding targets to expedite cultivar development.
