“…Rodríguez-Medina et al (2010) found similarity ranging from 0.40 to 1.00 among 43 accessions of a Cuban guava collection, which was evaluated using 7 microsatellite markers. High genetic variability was also found and reported by Corrêa et al (2011) for 88 Psidium accessions of the same collection, evaluated using AFLP markers. The 183 alleles of the 13 microsatellites were sufficient to separate the guava accessions from araçazeiro accessions.…”

“…However, this marker has a low reproducibility and is dominant (Esselink et al, 2003). Corrêa et al (2011) studied and compared the genetic similarity of 62 guava and 24 araçazeiro accessions by using amplified fragment length polymorphism (AFLP) markers and separated the genotypes into 2 groups, one formed by guava accessions and another by araçazeiro accessions with the inclusion of some guava accessions, with a similarity ranging from 28 to 98%. -Infante et al (2007) were the first to report and characterize Cuban guava accessions by using microsatellites.…”

ABSTRACT. This study aimed to investigate the genetic variability among guava accessions and wild Psidium species of the Embrapa Semiárido germplasm collection by using microsatellite loci to guide genetic resources and breeding programs, emphasizing crosses between guava and other Psidium species. DNA was extracted using the 2X CTAB method, and polymerase chain reaction products were analyzed on 6% denatured polyacrylamide gels stained with silver nitrate. The unweighted pair-group method using arithmetic average dendrogram generated from the distance matrix of the Jaccard coefficient for 183 alleles of 13 microsatellite loci was used for visualization of genetic similarity. The number of base pairs was estimated using inverse mobility method based on the regression of known-size products. Analysis of molecular variance was performed using total decomposition between and within guava accessions. The accessions showed similarity from 0.75 to 1.00, with the dendrogram presenting cophenetic value of 0.85. Five groups were observed: the first included guava accessions; the second, P. guineense accessions; the third, one accession of P. friedrichsthalianum; and the last 2 groups, P. cattleianum. The genetic similarity among P. SSR Psidium allelic database and accession divergence guineense and some guava accessions were above 80%, suggesting greater possibility to obtain interspecies hybrids between these 2 species. The genetic variability between the accessions was considered to be high (Φ ST = 0.238), indicating that guava genetic variability is not uniformly distributed among the 9 Brazilian states from where the accession were obtained. Obtaining a greater number of accessions by Brazilian states is recommended in order to have greater diversity among the species.

analYsis of Genetic distance Between access of the Gender Psidium BY ROUTE MARKERS ISSRaBstract-The objective of this study was to evaluate the genetic distance among 37 accessions of cultivated species Psidium guajava, L. (guava) and Araçás to the genus Psidium to the germplasm colection of the Universidade Estadual Norte Fluminense (UENF) by ISSR molecular markers. In the 17 selected markers, 216 polymorphic bands were obtained. By UPGMA method there was the formation of five main clusters. Accessions of araçá species, P. cattleyanum Sabine, were allocated in groups I and II. In group II was observed within the species P cattleyanum, closer to the guava. In group III was allocated the genotypes of the species P. guineense Sw (araçá-do-campo) and among the araçás, was the most closest to the guava. The guava genotypes were allocated to Group IV and V, confirming their high divergence. Molecular markers were efficient in evaluating intra and interspecific genetic distance for these species.

“…High genetic variability was also reported by da Costa and Santos (2013) among the 61 Psidium accessions of that same collection evaluated by microsatellite marker. Corrêa et al (2011) also reported high genetic variability among 88 Psidium accessions, with similarities ranging from 0.28 to 0.98 based on AFLP markers. These results indicate high discriminative power of SNP markers, even among genetically related materials when compared to results obtained with AFLP and SSR markers for the same collection of accessions.…”

ABSTRACT. The goal of this study was to analyze the genetic divergence among Psidium species accessions based on SNPs developed for Eucalyptus. Fifty-three Psidium accessions, including 47 P. guajava, were genotyped with EUCHIP60K. The dendrogram similarity ranged from 0.58 to 1.00, with a cophenetic value of 0.97. Five groups were identified at dendrogram cut point of 0.7: the first with 44 guava accessions, the second with 1 guava accession, the third with 3 P. guineense accessions, the forth with 2 guava accessions, and the fifth with 3 P. cattleianum accessions. The Bayesian analyses suggested seven subpopulations, with formation of two additional groups with guava accessions. Primers designed with Eucalyptus SNP sequences resulted in reliable Psidium amplicons on 6% polyacrylamide gels. In general, the SNP dendrogram agreed with biological genus structure, since different species were not grouped, indicating that transferability among Myrtaceae genus was possible and reliable.
