Última Estimates of the genetic parameters, optimum sample size and conversion of quantitative data in multiple categories for soybean genotypes - doi: 10.4025/actasciagron.v34i3.14015 Agronomy Matsuo, Éder; Universidade Federal de Viçosa; Sediyama, Tuneo; Universidade Federal de Viçosa; Cruz, Cosme Damião; Universidade Federal de Viçosa; Oliveira, Rita de Cássia Teixeira; Bacuri Pesquisa e Sementes; Cadore, Luiz Renato; Universidade Federal de Viçosa. The objective of this study was to estimate the genetic parameters and optimal sample size for the lengths of the hypocotyl and epicotyls and to analyze the conversion of quantitative data in multiple categories for soybean genotypes. A total of 85 soybean genotypes were analyzed in four experiments in a completely randomized design under greenhouse conditions at the Federal University of Viçosa, Brazil. The magnitude of the genetic parameter estimates characterized the influence of the genetic components in the phenotypic expression of the length of the hypocotyls and epicotyls of different soybean genotypes. The optimal size of the sample varied between the genotypes and the conversion of the quantitative data in multiple categories provided estimates of...

Ano: 2012 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/14015 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 Plant regeneration and histological study of the somatic embryogenesis of sugarcane (Saccharum spp.) cultivars RB855156 and RB72454 - doi: 10.4025/actasciagron.v36i1.16342 Agronomy Alcantara, Giovana Bomfim de; Universidade Federal do Paraná; Dibax, Roberson; Universidade Federal do Paraná; Bespalhok Filho, João Carlos; Universidade Federal do Paraná; Daros, Edelclaiton; Universidade Federal do Paraná. The development of an efficient regeneration system is crucial for the genetic transformation of sugarcane. The aims of this study were to regenerate plants from somatic embryos and analyze the origin and division pattern of cells during the different embryonic developmental stages of the sugarcane cultivars RB855156 and RB72454. For both cultivars, the best results for embryogenic callus induction were obtained with explant cultures on culture medium containing 13.5 µM 2,4-dichlorophenoxyacetic acid (2,4-D) followed by callus culture on solid medium with 4.5 µM 2,4-D. A higher rate of shoot induction was observed in RB855156 with the addition of 8.9 and 17.8 µM benzylaminopurine (BAP); this higher rate was also observed in RB72454 with the addition of...
