Grain legumes are characterised by their nutritional value, an ability to grow rapidly and improve soil health. This makes them a key rotation crop in promoting food security. However, yields are constrained by factors such as pests and diseases as well as vulnerability to poor soils, drought and other effects of climate change.This collection reviews the wealth of research addressing these challenges. Volume 2 assesses key research on particular types of grain legume with chapters on developing improved varieties as well as improvements in cultivation techniques. The book covers common beans, lentils, soybeans, groundnuts, cowpea, faba beans and pigeonpea.With its distinguished editorial team and international range of expert authors, this will be a standard reference for the grain legume research community and farmers of these important crops. It is accompanied by a companion volume which reviews general advances in breeding and cultivation techniques.

This collection features four peer-reviewed literature reviews on drought-resistant crops.The first chapter assesses the genes involved in drought and heat tolerance, as well as the physiological traits related to increased tolerance to abiotic stress in wheat. It reviews advances in our understanding of the molecular markers associated with these physiological traits, and the roles of key genes in determining a wheat plant’s response to heat and drought stress.The second chapter discusses mechanisms of drought resistance in rice. It reviews ways of assessing drought tolerance performance, identifying genes promoting drought tolerance through quantitative trait loci (QLT) analysis, as well as breeding for drought tolerance.The third chapter highlights the genetic diversity and quantitative trait loci (QTL) associated with the traits contributing to drought and heat tolerance in soybean. It also reviews genomic resources that can facilitate a better understanding of phenotype-genotype associations and formulate genomic-assisted breeding strategies.The final chapter addresses the polygenic nature of tolerance to drought and to heat in grain legumes. It reviews advances in understanding plant adaptation to stress, the assembly of molecular and phenotyping tools to support breeding and the development of tolerance through traditional and molecular breeding techniques.

This open access book is a compilation of protocols developed through a Coordinated Research Project of the Joint FAO/IAEA Center of Nuclear Techniques in Food and Agriculture, specifically focused on mutation breeding for resistance to Striga.
