Interpretive Summary: Soybean is an important protein and oilseed crop, but it’s growth is highly influenced by environmental factors such as photoperiod and altitude. Poor adaptability of soybean cultivars may result in a significant decrease in seed yield due to disruption of flowering or maturity. In order to help soybean breeders quickly select for traits that will help improve adaptability and yield of soybean to many growing environments, including those stressed by climate change, this review presents information on phenotypes, breeding resources, and genetic marker information.

Technical Abstract: Soybean is an important protein and oilseed crop, but it’s growth is highly influenced by environmental factors such as photoperiod and altitude. Poor adaptability of soybean cultivars may result in a significant decrease in seed yield due to disruption of flowering or maturity. It is therefore important to select cultivars adapted to specific regions of the world. Global climate change resulting in increasing temperature and associated water deficit stress may further challenge sustainable soybean production worldwide. Therefore, there is a need to understand genetic responses in soybean induced by environmental variables. In this review, we highlight previous research that shows how flowering in soybean is affected by several quantitative trait loci (QTLs) activated by photo-thermal responses. Cytogenetic stocks, including chromosome segment substitution lines, and their role in introgression of novel genes from wild soybean, are discussed. Genes showing responses to various environmental variables that affect soybean adaptability are reviewed and putative functions are suggested. These include genes regulating responses to temperature and heat stress, which were identified via genetic mapping and are presented as tools for developing adapted soybean cultivars.
