Resumo: Inbreds Poncirus trifoliata (L.) Raf x Rangpur limes (Citrus limonia Osbeck) from the orchard of Universidade Federal de Lavras, MG, Brazil, were obtained as rootstocks for pest and disease resistance. Studies comparing male and female progenitors with their inbreds were carried out: fruits harvested were measured, seed numbers were taken, and polyembryony index was determined by excising the embryos at several development stages and inoculating them in vitro. The trifoliate trend of male progenitor ('Trifoliata' lemon) kept the dominance over the normal female progenitor ('Cravo' lemon). No progenitor dominance for seed total number, viable seeds number, and fruit diameter was observed. Fruit polyembryony index obtained throught artificial pollination (2.39 embryos/seed) were maintained in inbred progenies (1.21 embryo/seed), indicating that such traits are able to be characterized as monoembryonics, although they were similar to the female progenitor which showed 1.41 embryo/seed.

Em estudos comparativos entre os parentais masculino e feminino com os híbridos, frutos coletados foram mensurados, suas sementes, contadas, e os embriões, excisados e inoculados in vitro, determinando-se a taxa de poliembrionia. Verificou-se que quanto às características número total de sementes, número de sementes viáveis e diâmetro total do fruto não houve influência dos parentais. A taxa de poliembrionia dos frutos obtidos pela polinização artificial (2,39 embriões/semente) não foi mantida nos frutos das progênies híbridas (1,21 embriões/semente), podendo estas ser caracterizadas como monoembriônicas, porém foi similar à do parental feminino, que em média apresentou 1,41 embrião/semente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRamos, José DarlanPasqual, MoacirRibeiro, Valtemir GonçalvesAntunes, Luís Eduardo Corrêa1997-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4747Pesquisa Agropecuaria Brasileira; v.32, n.10, out. 1997; 1047-1051Pesquisa Agropecuária Brasileira; v.32, n.10, out. 1997; 1047-10511678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4747/7286info:eu-repo/semantics/openAccess2015-03-31T18:28:35Zoai:ojs.seer.sct.embrapa.br:article/4747Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-31T18:28:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
