Pastures are the pillar of support for national beef and dairy farming, which is mostly carried out on pasture, resulting in around 160 million hectares occupied by pastures in Brazil. Among the various aspects of research that contribute to the establishment of quality pastures, the genetic improvement of forage plant species stands out; mainly tropical grasses. Embrapa's Active Germplasm Banks (BAGs) have allowed large increases in pasture productivity. However, there are certain niches that are still poorly served by the current supply of tropical forage grasses. There is a limited supply for areas with poor drainage and also of forage cultivars for use in integrated systems (ILP and ILPF), as most are poorly tolerant to soil waterlogging and/or shading. Within the continuous process of the Paspalum Improvement Program, genetic materials were identified in the BAG that are tolerant to abiotic stresses caused by soil waterlogging and shading. Therefore, it is possible that research will provide new cultivars of tropical forage grasses that meet these niches. The objective of this project is to develop Paspalum cultivars for use as forage crops that are more tolerant to areas of waterlogging and shading.
