Resumo: | The objective of this study was to evaluate the resistance of a group of clones and cultivars from the potato breeding program of Embrapa to Meloidogyne javanica. The experiment was conducted at Embrapa Temperate Climate, Pelotas / RS, under greenhouse conditions at temperatures of 25 ± 5°C. Individual potato plants of different genotypes [BRSIPR Bel, BRS F63 (Camila), CL02-05, F23-11-06, F32-02-06, F38-03-07, F189-09-06, F23-24-06 and F22-01-08], kept in pots with sterilized soil were inoculated with 5,000 eggs and J2 of M. javanica, using six replicates per treatment. The susceptible control, potato cultivar BRS Ana was inoculated with the same level of inoculum. Fifty-five days after inoculation, the number of galls on the roots of each plant was determined as well as the number of protuberances caused by nematodes in the different treatments. Then, the roots of each plant were processed for counting the number of eggs and J2, as well as determining the nematode reproduction factor (FR: final population / initial population). All genotypes were susceptible (FR> 1.00) to M. javanica. However, there were different levels of susceptibility among the cultivars tested. |

O experimento foi desenvolvido na Embrapa Clima Temperado, Pelotas/RS, em casa-de-vegetação sob temperaturas de 25±5oC. Plantas individuais de batata dos diferentes genótipos [BRSIPR Bel, BRS F63 (Camila), CL02-05, F23-11-06, F32-02-06, F38-03-07, F189-09-06, F23-24-06 e F22-01-08], mantidas em vasos com solo esterilizado, foram inoculadas com 5.000 ovos + J2 de M. javanica, utilizando-se seis repetições por tratamento. Como testemunha suscetível, plantas de batata da cultivar BRS Ana foram inoculadas com o mesmo nível de inóculo. Decorridos 55 dias da inoculação, avaliou-se o número de galhas nas raízes de cada planta e determinou-se o número protuberâncias (pipocas) causadas pelo nematoide/tubérculo nos diferentes tratamentos. Em seguida, as raízes de cada planta foram processadas para contagem do número de ovos + J2 e determinação do fator de reprodução do nematoide (FR: população final/população inicial). Todos os genótipos comportaram-se como suscetíveis (FR>1,00) à M. javanica. No entanto, verificaram-se diferentes níveis de suscetibilidade entre os materiais avaliados.Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/574710.1590/1983-21252017v30n230rcREVISTA CAATINGA; Vol. 30 No. 2 (2017); 536-540Revista Caatinga; v. 30 n. 2 (2017); 536-5401983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5747/pdfSchafer, Jaqueline TavaresGomes, Cesar BauerPereira, Arione da SilvaCruz, Fernanda FerreiraBarros, Danielle Ribeiro deinfo:eu-repo/semantics/openAccess2023-07-20T11:00:24Zoai:ojs.periodicos.ufersa.edu.br:article/5747Revistahttps://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:2024-04-29T09:46:24.362095Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
