Pleurotus is an important genus comprising several edible species of great commercial significance. These species are grown all across the world. The production areas of Pleurotus mainly belong to the Asian part and are gaining wide popularity across the globe owing to their promising nutritional gains. The demand for improved strains with high productivity has also been rising. The genetic improvement in Pleurotus started with a simple selection technique, which later utilized hybridization (intraspecific, interspecific and intergeneric) and mutation breeding. The traits such as productivity, sporelessness and quality improvement are important objectives on which most of the works have been done so far. However, new generation approaches such as molecular breeding, genetic transformation and genome editing techniques also added pace to the present improvement process. Hitherto, seven species of Pleurotus have been sequenced and a sizable data has been generated that can be used in further breeding programs. This paper discusses and summarizes various research findings on genetic improvement of Pleurotus and gives an outlook for future breeding programs.
