Resumen:
The objective of this review is to analyze and describe the impact that mode ofreproduction in Paspalum has on germplasm conservation, genetic improvement, andcommercialization of cultivars. Germplasm collection and conservation can now berethought considering the newly available information related to how diversity is allocatedin nature and how it can be transferred between the sexual and apomictic germplasmusing novel breeding approaches. An inventory of species and accessions conservedaround the world is analyzed in relation to the main germplasm banks. Because of theimportance of apomixis in Paspalum species different breeding approaches have beenused and tested. Knowledge related to the inheritance of apomixis, variable expressivityof the trait and techniques for early identification of apomicts has helped to improvethe efficiency of the breeding methods. Novel breeding techniques are also beingdeveloped and are described regarding its advantages and limitations. Finally, the impactof reproductive mode on the adoption of the released cultivars is discussed.
