Editorial: Mining and utilization of favorable gene resources in rice

Agriculture has been evolving along with the development of human society. Agricultural germplasm resources play a crucial role in supporting the development of human civilization (Doebley et al., 2006;Tian et al., 2021). With the change of agricultural population structure, there are new requirements for germplasm resources (Yu and Li, 2021). Combined with global climate change, crops should also be able to cope with the challenges of environmental stresses and maintain a stable increase in production (Shahzad et al., 2021). Subsequently, rice has new breeding requirements in production, quality, and yield (Zeng et al., 2017). This Research Topic covers multiple approaches to exploit rice germplasm, excavate and utilize the key genes, and understand the molecular basis of yield component traits.The classical mapping and cloning technique still play an important role in the discovery of new genetic loci.
