Resumo: The objective of this work was to assess the androgenic response, via microspore culture, of wheat genotypes with different levels of resistance to Gibberella zeae. The number of androgenic embryos per spike, and of green and albino plants was counted for the BRS 179 (moderately resistant), Frontana and Sumai 3 (resistant), and BRS 194, Embrapa 27, and Fielder (susceptible) genotypes. The degree of interference by the Fielder, Pavon 76, and Sumai 3 ovary-donor genotypes, used for co-culture with the microspore cells, was also assessed regarding androgenic response. Induction efficiency ranged from 0.33 embryo per spike for Embrapa 27 to 109.8 embryos for Frontana. Sumai 3 presented the second best response, and Embrapa 27 behaved as highly recalcitrant. The co-culture of ovaries from the Fielder genotype stands out from the others and positively interferes in the embryo induction rate. No significant differences were observed for the regeneration frequency of green plants; however, for albino plants, BRS 194 produced the highest rate. Frontana and Sumai 3 present the highest androgenic response rates and can be used in breeding programs for the rapid development of cultivars resistant to Gibberella zeae.

Contou-se o número de embriões androgenéticos por espiga, e de plantas verdes e albinas para os genótipos BRS 179 (moderadamente resistente), Frontana e Sumai 3 (resistentes), e BRS 194, Embrapa 27 e Fielder (suscetíveis). A interferência dos genótipos doadores de ovários Fielder, Pavon 76 e Sumai 3, utilizados para cocultivo das células de micrósporos, também foi avaliada na resposta androgênica. A eficiência de indução variou de 0,33 embrião por espiga para Embrapa 27 a 109,8 embriões para Frontana. Sumai 3 apresentou a segunda melhor resposta, e Embrapa 27 se comportou como altamente recalcitrante. O cocultivo de ovários do genótipo Fielder se destaca dos demais e interfere positivamente na indução dos embriões. Não foram observadas diferenças significativas para a regeneração de plantas verdes; no entanto, para plantas albinas, BRS 194 produziu as taxas mais altas. Frontana e Sumai 3 apresentam as mais elevadas taxas de resposta androgênica e podem ser explorados em programas de melhoramento para o rápido desenvolvimento de cultivares resistentes à Gibberella zeae.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Professor Florindo Castoldi from Universidade de Passo FundoCoelho, Mônica BossardiScagliusi, Sandra Maria MansurLima, Maria Imaculada Pontes MoreiraConsoli, LucianoGrando, Magali Ferrari2018-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25823Pesquisa Agropecuaria Brasileira; v.53, n.5, May 2018; 575-582Pesquisa Agropecuária Brasileira; v.53, n.5, May 2018; 575-5821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25823/14205https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/17524https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/17525https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/17526https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/17886https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/17887https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/18022https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25823/18023Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-08-13T13:38:43Zoai:ojs.seer.sct.embrapa.br:article/25823Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-08-13T13:38:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
