Última A comparison of RAPD and ISSR markers reveals genetic diversity among sweet potato landraces (Ipomoea batatas (L.) Lam.) - doi: 10.4025/actasciagron.v34i2.12616 Agronomy Moulin, Monique Moreira; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Rodrigues, Rosana; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Gonçalves, Leandro Simões Azeredo; Universidade Estadual do Norte Fluminense; Sudré, Cláudia Pombo; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Pereira, Messias Gonzaga; Universidade Estadual do Norte Fluminense Darcy Ribeiro. Small farmers have played an important role in maintaining genetic resources of traditional varieties. Collecting and characterizing germplasm, especially landraces and heirloom varieties, are strategic activities that would create a knowledge base describing the traditional varieties of a given region and reduce the risk of genetic erosion. The objectives of this work were as follows: collect sweet potato roots from rural properties and local markets in Rio de Janeiro State, Brazil; characterize the accessions using RAPD and ISSR molecular markers, comparing the efficiency in discrimination of these two types of molecular markers; and estimate the genetic variability of the population. Fifty-nine samples from rural properties and 19 from local markets... Palavras-chave: Genetic resources; Germplasm characterization; Genetic variability; Heirloom seeds. Ano: 2012 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/12616 Comparison of multiallelic distances for the quantification of genetic diversity in the papaya - doi: 10.4025/actasciagron.v33i1.11698 Agronomy Ramos, Helaine Christine Cancela; Universidade Estadual do Norte Fluminense; Pereira, Messias Gonzaga; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Gonçalves, Leandro Simões Azeredo; Universidade Estadual do Norte Fluminense; Amaral Júnior, Antonio Teixeira do; Universidade Estadual do Norte Fluminense; Scapim, Carlos Alberto; Universidade Estadual de Maringá. This study aimed to compare multiallelic distances to quantify genetic diversity in papaya. We evaluated forty-three individuals in the S2 generation, from the backcross between F1 (Cariflora x SS783) and Cariflora, and four accessions from the UENF/Caliman Germplasm Bank. Genetic distances used were Smouse and Peakall (1999), Kosman and Leonard (2005) and weighted index. Clustering among genotypes was performed using the hierarchical unweighted pair-group method with arithmetic mean analysis (UPGMA) and projection of the distance on the bidimensional plan. A high correlation between genetic distances was observed; however, through UPGMA group analysis, the distance determined by the weighted index provided the complete separation of 52BC1S2-08, 52BC1S2-29...

Ano: 2011 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/11698 Response to the selection in the 11th cycle of reciprocal recurrent selection among full-sib families of maize - doi: 10.4025/actasciagron.v35i4.17489 Agronomy Berilli, Ana Paula Cândido Gabriel; Instituto Federal do Espírito Santo; Pereira, Messias Gonzaga; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Trindade, Roberto dos Santos; Instituto Capixaba de Pesquisa; da Costa, Fabiane Rabelo; Instituto Nacional do Semiárido (INSA/MCTI); Cunha, Keila Silva da; Universidade Estadual do Norte Fluminense Darcy Ribeiro. The continuous gains in cycles of recurrent selection have raised disagreement among researchers. Two hundred and forty-two full-sib families were obtained from CIMMYT and Piranão populations and evaluated in a simple lattice design in two environments to estimate the response to selection in the 11th cycle of the UENF reciprocal recurrent selection program. No genotype x environment interaction was observed for most of the traits evaluated, indicating that a single recurrent selection program can be conducted for both sites. The population studied exhibited wide genotypic variability and heritability estimates ranged from 33 to 73%, indicating prospects of selection gain for the following cycles. The predicted genetic gain in yield was 12.90%. It is...
