Última Population structure and impact of recurrent selection on popcorn using EST-SSR markers Agronomy Guimarães, Amanda Gonçalves; Amaral Júnior, Antônio Teixeira do; Almeida Filho, Janeo Eustáquio de; Pena, Guilherme Ferreira; Vittorazzi, Cássio; Pereira, Messias Gonzaga. The success of any recurrent selection program depends on the genetic variability of the evaluated population, which is used to refer to the diversity of existing alleles at many genetic loci. Thus, the goal of the present study was to investigate the impact of recurrent selection across nine cycles of a UENF-14 popcorn population through the analysis of genetic diversity and structure using microsatellite markers (EST-SSRs). Genomic DNA was extracted from young leaves of 25 individuals from each cycle (C0, C1 C2, C3, C4, C5, C6, C7, and C8), totaling 225 samples from the UENF-14 population. Fifty EST-SSR markers were used for the analysis of genetic diversity across the recurrent selection cycles, 16 of which were polymorphic. Thirty-four alleles were...

Ano: 2018 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/35218 History of northern corn leaf blight disease in the seventh cycle of recurrent selection of an UENF-14 popcorn population Agronomy Ribeiro, Rodrigo Moreira; Amaral Júnior, Antônio Teixeira; Pena, Guilherme Ferreira; Vivas, Marcelo; Kurosawa, Railan Nascimento; Gonçalves, Leandro Simões Azeredo. To investigate the genetic resistance to northern corn leaf blight (Exserohilum turcicum) disease in the UENF-14 popcorn population and the inclusion of this trait in the analysis, two hundred ten popcorn half-sib families were evaluated using an incomplete block design with treatments arranged in replicates "Sets". Regarding the Families within "Set" (F/S) source of variation, enough genetic variability was found for northern corn leaf blight disease resistance to be explored in the next cycles of the UENF popcorn breeding program. The open-pollinated UENF-14 variety has a source of resistance to this disease in its genetic basis, given that it originated from crossing with an American cultivar with yellow grains that is resistant to disease. These... Tipo: Info:eu-repo/semantics/article Palavras-chave: Genética e melhoramento Exserohilum turcicum; Half-sib families; Zea mays. Genética e melhoramento.
