Chapter synopsis: Drought combined with heat is the major abiotic stress that threatens crop production. Climate changes are anticipated to intensify the occurrence of irregular precipitation patterns worldwide, which will further negatively affect crop production and food security. The success of soybean improvement under drought and heat stress depends on the discovery and utilization of genetic variations present in the germplasm. Identification of genetic diversities for traits related to drought and heat tolerance have helped identify genetic resources in soybean. In this chapter, advances in drought and heat tolerance in soybean are summarized by highlighting the genetic diversity and quantitative trait loci (QTL) associated with the traits contributing to drought and heat tolerance. In addition, genomic resources that can facilitate a better understanding of phenotype-genotype association and formulate genomic-assisted breeding strategies are discussed.
