Abstract
Soybean is an essential protein and oilseed crop, but environmental factors, such as photoperiod and altitude, highly influence its growth. Poor adaptability of soybean cultivars may result in a significant decrease in seed yield due to disruption of flowering or maturity. It is, therefore, vital to select cultivars adapted to specific regions of the world. Global climate change, causing increasing temperature and associated water deficit stress, may further challenge sustainable soybean production worldwide. Therefore, it is necessary to understand genetic responses in soybeans induced by environmental variables. This review highlights previous research showing how several quantitative trait loci (QTLs) activated by photo-thermal responses affected soybean flowering. We discuss cytogenetic stocks, including chromosome segment substitution lines, and their role in introgressing novel genes from wild soybeans. A review of genes showing responses to various environmental variables that affect soybean adaptability is also ensued, with putative functions suggested. These include gene response regulation to temperature and heat stress, identified via genetic mapping, and emerged as tools for developing adapted soybean cultivars. [ABSTRACT FROM AUTHOR]
