Resumo: The objective of this work was to evaluate the response of sugarcane genotypes to Meloidogyne javanica and Pratylenchus zeae. Sugarcane seedlings of the genotypes RB985944, RB987932, RB877935, RB855156, RB935744, RB996961, RB925345, RB935581 and RB966928 obtained from tissue cultures and maintained in pots with sterilized soil in a greenhouse were inoculated with 5,000 eggs + second-stage juveniles of M. javanica or 1,600 of P. zeae per plant, using six replicates per treatment. Tomato (Rutgers) and sorghum (BRS506) plants were used as control and proof of viability of the inoculum for the M. javanica and P. zeae, respectively. The number of root-knot in the plants inoculated with M. javanica, final nematode population and reproduction factor (RF) of both nematodes were evaluated at 120 days after inoculation. The averages of the different variables were compared by the Scott-Knott's clustering test at 5%. The nematodes M. javanica and P. zeae showed RF>1.00 in all sugarcane genotypes assessed, however, different levels of susceptibility were found. The lowest reproduction of the nematodes was found in the genotypes RB008347, RB877935, RB975944 and RB987932 (M. javanica) and RB987932 and RB966928 (P. zeae).

Mudas de cada material genético (‘RB008347’, ‘RB975944’, ‘RB987932’, ‘RB877935’, ‘RB855156’, ‘RB935744’, ‘RB996961’, ‘RB925345’, ‘RB935581’ e ‘RB966928’), obtidas da cultura de tecidos e mantidas em vasos com solo esterilizado, em casa de vegetação, foram inoculados com 5.000 ovos + juvenis de segundo estádio de M. javanica ou 1.600 P. zeae/planta, utilizando-se seis repetições por tratamento. Para controle e a comprovação da viabilidade do inoculo, utilizaram-se plantas de tomate 'Rutgers' e sorgo ‘BRS 506’ para M. javanica ou P. zeae, respectivamente. Decorridos 120 dias avaliou-se o número de galhas nas plantas inoculadas com M. javanica; a população final de nematoide e o fator de reprodução (FR) de ambos nematoides. A seguir, as médias das diferentes variáveis foram comparadas entre si pelo teste de agrupamento de Scott-Knott a 5%. Verificou-se que embora M. javanica e P. zeae tenham apresentado FR>1,00 em todos os genótipos de cana-de-açúcar testados, forma observados diferentes níveis de suscetibilidade.  Desse modo, a menor reprodução do nematoide das galhas foi observada em ‘RB008347’, ‘RB877935’, ‘RB975944’ e ‘RB987932’; e de P. zeae em ‘RB987932’ e ‘RB966928’.Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/5702REVISTA CAATINGA; Vol. 30 No. 2 (2017); 530-535Revista Caatinga; v. 30 n. 2 (2017); 530-5351983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5702/pdfBellé, CristianoKulczynski, Stela MarisKuhn, Paulo RobertoDonini, Lorena PastoriniGomes, Cesar Bauerinfo:eu-repo/semantics/openAccess2018-12-07T16:01:30Zoai:ojs.periodicos.ufersa.edu.br:article/5702Revistahttps://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:2018-12-07T16:01:30Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)false
