Resumo: | The present study aimed to evaluate Capsicum accessions for resistance to Meloidogyne incognita race 3, Meloidogyne javanica and Meloidogyne enterolobii. Two experiments with different genotypes of hot and sweet peppers were carried out in a completely randomized design. The first experiment was conducted in a 31 x 3 factorial scheme with 27 genotypes of Capsicum annuum, two cultivars of hot pepper, one line of Capsicum frutescens and tomato 'Santa Cruz Kada', and three species of nematodes (M. incognita race 3, M. javanica and M. enterolobii). In the second experiment, we used a factorial scheme 39 x 3 with 36 accessions of C. annuum, two hot pepper cultivars and the 'Santa Cruz Kada' tomato and three nematodes species mentioned earlier. The total number of eggs and second-stage juveniles (TNEJ), number of eggs and second-stage juveniles per gram of root (NEJGR), reproduction index (RI) and reproduction factor (RF) were evaluated. Based on RI and RF, the genotypes CNPH 185, CNPH 187 and CNPH 680 were resistant and very resistant to M. incognita race 3 and M. javanica, simultaneously. The C. frutescens line presented resistance to the three root-knot nematode species. |

Foram realizados dois experimentos, comdiferentes genótipos de pimentas e pimentões, em delineamento inteiramente casualizado sendo o primeiro em esquema fatorial 31 x 3 com 27 genótipos de Capsicum annuum, duas cultivares de pimenta, uma linhagem de Capsicum frutescens, o tomateiro ‘Santa Cruz Kada’ e três espécies de nematoides (M. incognita raça 3, M. javanica e M. enterolobii). No segundo experimento foi utilizado esquema fatorial 39 x 3 com 36 acessos de C. annuum, duas cultivares de pimenta, o tomateiro ‘Santa Cruz Kada’ e três espécies de nematoides mencionadas anteriormente. Avaliou-se o número total de ovos e juvenis de segundo estádio (NTOJ), número de ovos e juvenis de segundo estádio por grama de raízes (NOJGR), índice de reprodução (IR) e fator de reprodução (FR). Com base no FR e IR os genótipos CNPH 185, CNPH 187 e CNPH 680foram resistentes e muito resistentes a M. incognita raça 3 e M. javanica, simultaneamente. A linhagem de C. frutescens apresentou resistência às três espécies de nematoides de galha.EDUFU2018-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3746010.14393/BJ-v34n2a2018-37460Bioscience Journal ; Vol. 34 No. 2 (2018): Mar./Apr.; 312-325Bioscience Journal ; v. 34 n. 2 (2018): Mar./Apr.; 312-3251981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/biosciencejournal/article/view/37460/21912Brazil; ContemporaryCopyright (c) 2018 Renato Silva Soares, Edgard Henrique Costa Silva, Willame dos Santos Candido, Guilherme Matos Martins Diniz, Francisco José Becker Reifschneider, Pedro Luiz Martins Soares, Leila Trevisan Brazhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSoares, Renato SilvaSilva, Edgard Henrique CostaCandido, Willame dos SantosDiniz, Guilherme Matos MartinsReifschneider, Francisco José BeckerSoares, Pedro Luiz MartinsBraz, Leila Trevisan2022-02-15T14:21:46Zoai:ojs.www.seer.ufu.br:article/37460Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-15T14:21:46Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
