Resumo: | The aim of this work was to select F4 lettuce families, derived from the cross 'Veronica' x 'Salinas 88 ', for summer cropping, type of leaves, and for resistance to Meloidogyne javanica and to Lettuce mosaic virus (LMV). First, evaluations were made for leaf colour, leaf limb, border type, and heat tolerance in the fi eld, in a complete blocks desing, in 15 F4 families previously selected, parent cultivars and, as control, thecultivar Regina 71 (butterleaf and tolerant to heat). Five replicates and eight plants per plot were used. As second step, the families were evaluated in greenhouse, in 128-cell expanded polystyrene trays, for resistance to LMV and root-knot nematodes. Score means of each family were compared to the means of each parental cultivar byDunnett test at 5% probability. Family AFX007B-140-21, homozygous for root-knot nematodes, for LMV and heat tolerant, was the most promising. The cross between crisp and butter leaf cultivars can originate promising lineages both with crisp and butter leaves. |

Primeiramente, avaliaram-se a coloração da folha, tipos de borda e limbo foliares, além da tolerância ao calor no campo, em blocos ao acaso compostos pelas 15 famílias F4 previamente selecionadas, pelas cultivares parentais e pela cultivar testemunha Regina 71 (folhas lisas e tolerante ao calor), com cinco repetições e oito plantas por parcela. Na segunda etapa, as famílias foram avaliadas quanto à resistência ao LMV e ao nematóide-das-galhas, em bandejas de128 células acondicionadas em estufa. As médias das notas atribuídas a cada família foram comparadas às médias de cada cultivar parental pelo teste de Dunnet (5%). A família AFX007B-140-21, homozigota resistenteaos nematóides e ao LMV e, também, tolerante ao calor, foi a mais promissora. O cruzamento entre uma cultivar de folhas crespas e soltas com uma de folhas crespas e repolhuda, pode originar linhagens promissoras tanto de folhas crespas quanto de folhas lisas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, FAPEMIG, UFLA, FAEPESilva, Renata RodriguesGomes, Luiz Antônio AugustoMonteiro, Aline BeraldoMaluf, Wilson RobertoFilho, José Luiz Sandes de CarvalhoMassaroto, João Aguilar2008-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/483Pesquisa Agropecuaria Brasileira; v.43, n.10, out. 2008; 1349-1356Pesquisa Agropecuária Brasileira; v.43, n.10, out. 2008; 1349-13561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/483/5538info:eu-repo/semantics/openAccess2014-07-17T17:30:11Zoai:ojs.seer.sct.embrapa.br:article/483Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T17:30:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
