Resumo: | A nutrient solution technique was used to screen 391 sorghum genotypes (181 from BAG-sorghum, 71 from CNPMS, 17 SEPON from ICRISAT and 122 from sweet sorghum collection) for Al tolerance. The differential behavior was based on the root growth of young sorghum plant grown in nutrient solutions with varied Al (0.0, 2.25 and 4.5 mg of Al/l for grain sorghum and 0.0, 2.5 and 5.0 mg of Al/l for sweet sorghum). For comparison purposes, the relative seminal root length (SRRL = SRL+Al/SRL-Al, where SRL = Seminal Root Rength and SRRL = Seminal Root Relative Length) was estimated. Based upon the percentual frequency distribution of SRRL values obtained for the different genotypes tested and based upon the SRRL values of SC 208 (Al susceptible) and SC 283 (Al-tolerant) three classes of differential responses to Al were identified: Susceptible (SRRL <0.50). Intermediate (0.50 < SRRL <0.71) and Tolerant (SRRL > 0.70). Among the materials tested, the following were classified as being tolerant to Al: IS 3625,IS 7173 C (SC 283) IS 12666, 5DX61/6/2, 3DX57/1/1/91O, 156-P-5-Serere-1, 9DX9/11, Brandes, MN 4004 and MN 1204. The technique proved to be effective to screen large number of line for Al tolerance and should be used as a tool in a breeding program. |

A avaliação do comportamento diferencial dessas linhagens baseou-se no crescimento da raiz seminal primária de plantas jovens de sorgo, em solução nutritiva contendo níveis variados de Al (0,0; 2,25; e 4,5 mg de Al/l para sorgo granífero e 0,0; 2,5; e 5,0 mg de Al/l para sorgo sacarino). A característica usada para a comparação entre genótipos foi o comprimento relativo da raiz seminal (CRSS = CRS+Al/CRS-Al onde CRS = comprimento da raiz seminal). Baseando-se na distribuição percentual dos valores de CRRS, obtidos nas diferentes linhagens, e nos valores de CRRS, encontrados nos materiais controles SC 208 (sensível ao Al) e SC 283 (tolerante ao Al), três classes de resposta ao alumínio foram identificadas: sensível (CRRS <0,50), intermediária (0,50 <CRRS <0,71) e tolerante (CRRS >0,70). Dentre os materiais avaliados as seguintes linhagens apresentaram tolerância aos níveis de 4,5 ou 5,0 mg de Al/l: IS 3625, IS 7173 C (SC 283), IS 12666, 5DX61/6/2, 3DX57/1/1/910, 156-P-5-Serere-1, 9DX9/11, Brandes, MN 4004 e MN 1204. O processo mostrou-se eficiente na avaliação de grande número de linhagem, quando se visa a tolerância ao alumínio, sendo recomendada como técnica auxiliar em programas de melhoramento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFurlani, Pedro R.Bastos, Candido R.Borgonovi, Renato A.Schaffert, Robert E.2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14331Pesquisa Agropecuaria Brasileira; v.22, n.3, mar. 1987; 323-330Pesquisa Agropecuária Brasileira; v.22, n.3, mar. 1987; 323-3301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14331/8243info:eu-repo/semantics/openAccess2014-09-29T18:50:12Zoai:ojs.seer.sct.embrapa.br:article/14331Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-29T18:50:12Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
