“…A análise multivariada em estudos sobre divergência genética tem sido uma ferramenta intensivamente utilizada em pesquisas, em várias culturas, como feijão-preto (Elias et al, 2007), trigo (Condé, et al, 2010), milho (Dotto et al, 2010), girassol (Vogt et al, 2010) e soja (Azevedo et al, 2004;Marques, 2010e Almeida et al, 2011.…”

A divergência genética é um dos mais importantes parâmetros avaliados por melhoristas de plantas, na fase inicial de um programa de melhoramento genético. Diante disso, objetivou-se com este trabalho avaliar, por meio de técnicas multivariadas, a divergência genética entre 48 genótipos de soja, cultivados em várzea irrigada no Estado do Tocantins, com o intuito de identificar as combinações mais promissoras para produzir recombinações superiores, tanto destinados a produção de óleo e farelo, como do grupo especial, destinados ao consumo humano. O experimento foi conduzido no município de Formoso do Araguaia, TO, em cultivo de várzea irrigada na entressafra de 2010. O delineamento experimental foi o de blocos ao acaso, com quatro repetições. Verificou-se variabilidade entre os genótipos testados. Os resultados dos métodos de agrupamento de Tocher, UPGMA e Variáveis Canônicas foram concordantes entre si e detectaram quatro grupos distintos. As seguintes hibridações são promissoras para produção de grãos de soja destinados a óleo e farelo: M-Soy 8766, M-Soy 9144, A 7002 e M-Soy 9056 com Amaralina e cruzamentos entre M-Soy 8766, M-Soy 9144 e Amaralina com BRSMG 790A, BRS 257, BRS 216 e BRS 213 e são indicados visando a genótipos de soja especiais para alimentação humana.

“…Multivariate analysis techniques have been routinely used in the study of genetic divergence, since they simultaneously consider the evaluated variables of the genotypes, as well as their correlation (Condé et al, 2010). In clustering methods, the number of groups to be established is not known a priori, and different methods provide different results.…”

The objective of this study was to evaluate the genetic diversity for physical and chemical characteristics of fruits of 47 'Ubá' mango accessions in the Zona da Mata Mineira. The fruits physiologically mature of the 47 accessions were coming from the experimental orchard of Fazenda Sementeira, located in the Municipality of Visconde do Rio Branco-MG, an orchard of the Federal University of Viçosa, MG. The fruits were harvested and analyzed for the following characteristics: fruit mass (g); flesh firmness; peel and pulp color; percentage of seeds, peel and pulp; titratable acidity (TA); soluble solids (SS); vitamin C; and carotenoids. A completely randomized design was used, with 47 accessions, four replications (plants per access), and twenty fruits per plot (five fruits per plant). Dissimilarity measures were obtained, and clustering techniques were applied for the subsamples. The most similar accessions were 34 and 48, and the most distant were 11 and 55; carotenoid content was the characteristic that most contributed to the divergence between accessions. The cluster analysis showed the formation of two groups by the Tocher and UPGMA methods, which demonstrates the existence of genetic variability in 'Ubá' mango trees in the Zona da Mata of Minas Gerais. In view of this, the accessions discussed here have potential for use in breeding programs, aiming at obtaining good materials for the industry.

This study aimed to evaluate the genetic diversity among 28 peach cultivars and two nectarine cultivars, describing the most important characters in the diversity evaluation. The study was developed at the Federal University of Viçosa -Brazil, and the following characteristics were evaluated: fruit mass, suture, equatorial and polar diameters, firmness, soluble solids (SS), titratable acidity (TA), SS/TA, ascorbic acid and carotenoids contents, skin and flesh color (coordinate b* and hue angle -°h). Genetic diversity in peach and nectarine cultivars enabled the formation of seven, six and six groups in the 2011, 2012 and 2013 crop years, respectively. The features that most contributed to this diversity were fruit mass, skin and flesh °h and firmness. The greatest genetic divergence was observed between
