Prolific seed production is certainly one trait shared by many invasive species, which Wineberry is. We are not aware of research investigating the fecundity (fertility or reproductive potential) of Wineberry, since cultivated brambles (raspberry, blackberry, and their hybrids) already fruit sufficiently prolifically, plus spread readily if their arching branches are allowed to root where they touch the ground. Increasing the reproductive potential of cultivated brambles is probably counter-productive, especially since while some are derived from locally native species (at least in part), not all are locally native and we do not want to create more invasive species. Granted, genetic engineering could still alter current crop types to make them more resilient in the face of environmental stressors (drought, soil too wet, etc.), but brambles are probably not a high priority for such research given their already-high level of adaptability. In comparison, research is looking into making grains and other staples more tolerant of drought, saltwater intrusion, and other issues, especially in other regions that depend on such crops as a dietary or economic staple.
