Última Genetic similarity among soybean (Glycine max (L) Merrill) cultivars released in Brazil using AFLP markers Genet. Mol. Biol. Bonato,Ana Lídia V.; Calvo,Eberson S.; Geraldi,Isaias O.; Arias,Carlos Alberto A.. Genetic similarity among soybean genotypes was studied by applying the amplified fragment length polymorphism (AFLP) technique to 317 soybean cultivars released in Brazil from 1962 to 1998. Genetic similarity (GS) coefficients were estimated using the coefficient of Nei and Li (Nei and Li 1979), and the cultivars were clustered using the unweighted pair-group method with averages (UPGMA). The parentage coefficients of 100 cultivars released between 1984 and 1998 were calculated and correlated with the genetic similarity obtained by the markers. The genetic similarity coefficients varied from 0.17 to 0.97 (x = 0.61), with 56.8% of the coefficients being above 0.60 and only 9.7% equal to or less than 0.50. The similarity coefficients have remained constant... Tipo: Info:eu-repo/semantics/article Palavras-chave: AFLP; Genetic similarity; Molecular markers; Parentage coefficient; Soybean. Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572006000400019 Genetic characterization of ninety elite soybean cultivars using coefficient of parentage PAB Miranda,Zilda de Fátima Sgobero; Arias,Carlos Alberto Arrabal; Prete,Cássio Egidio Cavenaghi; Kiihl,Romeu Afonso de Souza; Almeida,Leones Alves de; Toledo,José Francisco Ferraz de; Destro,Deonisio. The objective of this work was to estimate the coefficient of parentage and to understand the genetic structure of 90 elite soybean cultivars, which are adapted to different Brazilian environments. A total of 4,005 coefficients of parentage (f) were obtained and used to group the cultivars by UPGMA method. The constructed dendrogram showed several related cultivar groups which shared similar ancestors and clearly showed the genetic structure of the main Brazilian cultivars. Effective population sizes (Ne) were also estimated for cultivars in different generations. The average f = 0.2124 value, obtained from cultivars classified into four decades according to the release year, suggested effective soybean population sizes of 11 and 13 calculated using...
