“…Para identificar os caracteres mais importantes para a divergência, estimou-se a contribuição relativa para a divergência genética pelo método proposto por Singh. Neiva et al (2011) avaliando caracteres morfológicos. A dissimilaridade encontrada neste artigo pode ser explicada pelos maiores teores de matéria seca de ramas, fibra em detergente neutro, fibra em detergente ácido e menores teores de nutrientes digestíveis totais e fósforo em relação aos genótipos BD-31TO e Cambraia.…”

RESUMOAtentando-se à necessidade de adoção de sistemas agrícolas mais sustentáveis, é importante que os programas de melhoramento de batata-doce procurem aumentar além da produtividade de raízes a produtividade e a qualidade de ramas para a produção de silagem. Objetivou-se avaliar a divergência genética e a importância de caracteres associados à produção e qualidade de silagem de ramas em genótipos batata doce. O experimento foi conduzido no Campus JK da Universidade Federal dos Vales do Jequitinhonha e Mucuri no delineamento experimental em blocos casualizados, com 12 tratamentos e quatro repetições. Foram avaliadas doze características de ramas e silagem. Verificou-se variabilidade genética entre os genótipos, sendo possível a seleção de genitores divergentes para futuros programas de melhoramento para produção de silagem. Os genótipos BD-54 e BD-31TO foram os mais divergentes em relação aos demais, sendo indicada a sua utilização em cruzamentos visando o melhoramento da cultura para silagem, uma vez que o elevado desempenho per se de todos os genótipos avaliados já foi verificado em trabalhos anteriores. As características Na, NDT e FDN foram aquelas que mais contribuíram para a divergência. Palavras-chave: alimentação animal, análise multivariada, Ipomoea batatas, melhoramento genéticoGenetic diversity and importance of traits in sweet potato genotypes aiming at silage production ABSTRACTIn view of the need for the adoption of more sustainable agricultural systems, it is important that the breeding programs for sweet potato seek to increase, besides the productivity of roots, the productivity and quality of vines for silage making. The objective of this study was to evaluate the genetic diversity and the importance of traits related to production and quality the of silage of vines of sweet potato genotypes. The experiment was conducted on the JK Campus of the Federal University of Vales do Jequitinhonha e Mucuri, in a randomized-block design with 12 treatments and four replicates. Twelve traits of vines and silage were evaluated. Genetic variability was detected among the genotypes, allowing for the selection of divergent genotypes for future breeding programs for silage production. Genotypes BD-54 and BD-31TO were the most divergent, and so they are indicated for use in crosses aiming at the breeding of this crop for silage-making, given that the high performance per se of all evaluated genotypes has already been verified in previous studies. The Na, TDN, and NDF traits were those that most contributed to divergence.

“…Despite the high genetic variability, changes in consumer habits and the lack of research on culture have contributed to the loss of important genotypes. It is extremely important for the maintenance of sweet potato accessions in Germplasm Banks (GB's), and the subsequent evaluation of different growing regions (Neiva et al, 2011). By having a high genetic variability, sweet potatoes can be selected for numerous purposes (Gonçalves et al, 2011;Neiva et al, 2011).…”

“…In Brazil, three GBs of sweet potatoes are referenced in the literature: 1) Embrapa -CNPH created in the 1980s with 324 accessions, located in Brasilia City (Ritschel and Huamán, 2002); 2) Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM) situated in Diamantina City (Minas Gerais state) with 65 accessions (Neiva et al, 2011); and 3) Universidade Federal do Tocantins (Tocantins State) with 20 accessions, created in the 1990s (Martins et al, 2012). We used the Embrapa Coastal Tableland collection, located in Umbaúba City (Sergipe State), the first in the Northeastern region.…”

The sweet potato, Ipomoea batatas (L.) Lam has its origin in Tropical America. In Sergipe State (Brazil), its production is very important, and to explore its potential in local agriculture in the State, the Embrapa Coastal Tableland created a collection with 52 accessions located in Umbaúba City. Some accessions were from germplasm belonging to Embrapa vegetables and others from local farmers of Sergipe. Here, we provide the first data on the genetic diversity and structure of sweet potato collection of SPGB using random amplified polymorphic DNA (RAPD) markers. RAPD data were used to determine genetic variability via a model-based Bayesian procedure (structure) and molecular variance analysis (AMOVA). In addition, Shannon index, genetic diversity and Jaccard coefficients were also estimated. RAPD was efficient for the analysis of genetic diversity to identify groups and measure the genetic distance between accessions. The markers showed that the collection had a high level of polymorphism. By UPGMA, we separated three groups of genotypes and identified two reconstructed populations by structure software.

“…Due to its higher genetic variability, the sweet potato can be used for different kinds of purposes. (Gonçalves Neto et al, 2011;Neiva et al, 2011). It can be used as human and animal food and for food, fabric, paper, cosmetics, adhesives and alcohol industries (Cardoso et al, 2005).…”
