Bell pepper rootstocks with multiple resistance to soilborne diseases

Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well Embrapa’s new hybrid, BRS Acará, were evaluated rootstocks for the bell pepper Margarita (Syngenta) Pampa (Clause) scions, under natural infestation of Ralstonia pseudosolanacearum, upon artificial inoculation with a) ten isolates, b) one Phytophthora capsici isolate, c) Meloidogyne incognita race 1, d) enterolobii (only c d). Grafted peppers consistently showcased a higher productivity than did non-grafted ones R. pseudosolanacearum infestation, genotype affected fruit size distribution. Rootstocks presented resistance (scions) 6 out 10 isolates. Acará displayed an immune-like response P. capsici, while was moderately resistant (25% symptomatic plants) susceptible (100% plants). immune M. but slightly (AF-8253 Acará) or (Fortaleza) enterolobii. Fortaleza, is recommended managing bacterial wilt, blight, root-knot nematodes.
