INTA Delta begins propagation of seven Creole willow clones for ecological restoration in Paraná

2025-12-04 -

As a result of the rescue, domestication and registration work carried out by Teresa Cerrillo, a leading researcher in Salix Genetic Improvement, within the framework of the National Genetic and Forest Resources Programs of INTA, the multiplication and propagation of seven clones of Creole willow (Salix humboldtiana) began recently registered in the National Seed Institute (INASE) by INTA Delta del Paraná.

This line of research provides certified genetic material and guarantees the traceability of the specimens destined to recompose degraded environments. The registered clones are seven materials registered with the INASE: • Bank of the Carabelas River INTA* (Reg. 22794) • San Pedro 1 INTA* (Reg. 22793) • Riacho Victoria 1 INTA* (Reg. 22791) • Riacho Victoria 4 INTA* (Reg. 22792)• Diamond Coast 1 INTA* (Reg. 22788)• Diamond Coast 3 INTA* (Reg. 22789)• Diamond Coast 5 INTA* (Reg. 22790) Restoration of the riparian forest and production of seedlingsThis first escalation in the propagation of clones marks a relevant advance for the use of native willows in environmental restoration within the Paraná Delta. The specimens will be used to generate connectivity modules in the riparian landscape, contributing to the conservation of the species within its natural habitat. In addition, the project will strengthen the production of seedlings in the INTA Delta nursery, which will have certified material available for conservation initiatives, revegetation and protection works coastal. The clones can be purchased through the Cooperating Association of the Paraná Delta Agricultural Experimental Station, as well as from producers belonging to the Delta Nursery Group.
