Interpretive Summary: Peanuts are a highly nutritious and highly-valued crop worldwide; but achieving competitive yield and quality is often challenged by biotic and abiotic stresses as well as relatively high production requirements in comparison with other crops. To successfully address these challenges, it is important to understand peanut physiology along with its essential requirements for growth and development. These include soil, water and germination requirements. An indepth study of these requirements for optimum peanut growth and production is presented.

Technical Abstract: The research achievements in peanut physiology have been numerous in recent years. These achievements are predominant in the areas of crop requirements for sustainable production, plant growth and development, mechanisms of adaptation to biotic and abiotic factors, and, more recently, development of high-throughput tools for phenotyping. Along with the achievements in genome sequencing and genetic mapping technologies, plant physiology discoveries and advancements in HTP technologies pave the way for implementation of new strategies in peanut breeding, i.e. molecular breeding and genomic selection. These strategies appear more robust than traditional breeding for predicting valuable traits for increased yield and adaptation to environmental conditions; and allow pyramiding these traits more effectively in future peanut cultivars to meet production requirements for the specific geographical regions in which cultivars will be grown.
