description Guava is a highly important fruit crop worldwide; however, a severe phytosanitary problem caused by the parasitism of Meloidogyne enterolobii has been limiting guava yields in Brazil and in several countries. The incidence of the nematode M. enterolobii results in significant decreases in yield, often resulting in plant death in the medium term. Considering a contribution to control tools, the objective of this study was to assess the resistance of 37 accessions of Psidium guajava grown in a greenhouse to M. enterolobii. Seedlings from seeds of each accession were inoculated with 4,000 eggs of M. enterolobii when they were at the three- to six-leaf stage, in two experiments. The root system of each plant was collected at 135 days after inoculation for extracting nematode eggs. The eggs were counted in three aliquots of 1 mL plant-1, and the obtained data were subjected to analysis of variance, which showed significant differences among accessions and among plants of the same accession. Accessions were classified regarding resistance based on the reproduction factor (RF = Pf / Pi = 4,000). The P. guajava germplasm studied showed a significant variability in responses to M. enterolobii; resistant plants were identified for accessions A08, A15, A26, A13, and A30A in Experiment I and for accessions A31, A11, A16, A30A, GF3, and A08 in Experiment II; the accessions A08 and A30A stood out by presenting resistant plants in both experiments.

A incidência do nematoide resulta em acentuada queda de produtividade e, na maioria das vezes, as plantas morrem em médio prazo. Visando a contribuir com ferramentas de controle, avaliou-se a reação de 37 acessos de Psidium guajava em casa de vegetação quanto à resistência a M. enterolobii. As mudas de cada acesso foram produzidas a partir de sementes e, no estádio de três a seis pares de folhas, foram submetidas à inoculação com 4.000 ovos de M. enterolobii, em dois experimentos. Cento e trinta e cinco dias após a inoculação, coletou-se o sistema radicular de cada uma das plantas para a extração de ovos. As contagens de ovos foram feitas em três alíquotas de 1 mL/planta e foram submetidas à análise de variância que indicou diferenças significativas entre acessos e entre plantas de mesmo acesso. A classificação dos acessos quanto à resistência foi feita pelo fator de reprodução (FR=Pf/Pi, Pi= 4.000). Pelo estudo do germoplasma de P. guajava, observou-se grande variabilidade quanto à reação a M. enterolobii, sendo que, no Experimento I, plantas resistentes foram encontradas nos acessos A08, A15, A26, A13 e A30A e, no Experimento II, nos acessos A31, A11, A16, A30A, GF3 e A08, com a detecção de plantas resistentes nos acessos A08 e A30A nos dois experimentos.Universidade Federal Rural do Semi-Árido2024-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1148510.1590/1983-21252024v3711485rcREVISTA CAATINGA; Vol. 37 (2024); e11485Revista Caatinga; v. 37 (2024); e114851983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11485/11551Copyright (c) 2024 Revista Caatingainfo:eu-repo/semantics/openAccessOliveira, Patrícia Gomes deQueiroz, Manoel Abilio deCastro, José Mauro da Cunha eSilva, Maurício Moisés Pereira da2024-09-12T12:55:42Zoai:ojs.periodicos.ufersa.edu.br:article/11485Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-09-12T12:55:42Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)false
