As sessile organisms, crops must deal with and adapt to environmental abiotic stresses such as drought, salinity and extreme temperature during the growth and development for achieving better fitness. With the rapid development of molecular genetics, numerous key genes and extraordinary haplotypes involved in responding and adapting to abiotic stresses have been revealed and characterized, and the underlying molecular mechanisms of their function have also been deciphered. Moreover, a multi-level complex molecular network has been gradually formed to comprehensively understand how plants adapt and confer the tolerance to abiotic stresses. In particular, China has made seminal progresses with respect to the staple crops responding to drought, salinity and temperature stresses. Here we tentatively summarize these cutting-edge progresses and analyze the potential development trend, the bottlenecks and constraining factors in this research area. We also list out the prospective suggestions for the mid- and long-term development layout to promote the transition to the intelligent breeding based on environmental adaptability, which will be important to ensure the continuous and stable crop yield.
