“…The affinity between P. guajava and P. guineense is corroborated in the work of Oliveira et al (2014), who verified greater genetic proximity between P. guajava and P. guineense, when evaluating the genetic divergence between accesses of the genus Psidium, via molecular markers.…”

-Mini-grafting is a type of grafting that has been indicated to increase efficiency of forest and fruit species propagation. the aim of this study was to evaluate the mini-grafting technique as a method for propagation of guava grafted on intra or interspecific rootstock. The experimental design was randomized blocks, with four treatments, five replications and plots consisting of ten plants, in a 2 2 factorial arrangement, and factors consisted of rootstocks and canopy cultivars. Rootstocks used were Psidium guajava and Psidium guineense. the canopy used was Paluma and Cortibel 1 cultivars. Only the canopy used had an effect on the percentage of grafting success of 52, 54, 82 and 84%, respectively, for 'Cortibel 1'/P. guineense; 'Cortibel 1'/P. guajava; 'Paluma'/P. guineense; 'Paluma'/P. guajava combinations. Mini-grafting was effective for guava propagation on intra or interspecific rootstocks. The average production time for 'Paluma' and 'Cortibel 1' saplings grafted on P. guajava or P. guineense, for mini-grafting, was 351 days, so that 'Paluma' seedlings were more vigorous than those of 'Cortibel 1'.

“…Sitther et al (2014) reported the formation of six groups composed of eight accessions of P. guajava, including three species of wild Psidium accessions of P. friedrichsthalianum, P. guineense, and P. sartorianum in the United States germplasm. Oliveira et al (2014) found greater proximity of P. cattleianum with guava accessions. However, these species possess proven differences concerning evolutionary distance in relation to guava, mainly because it is polyploid, being evidenced different ploidy levels, such as tetraploid, heptaploide, or octaploide (Costa et al, 2008;Ray, 2002;Singh and Sehgal, 1980;Hirano, 1967).…”

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.

“…Through research developed with other species of the same family, it was possible to detect the presence of variability regarding the amount of polymorphic fragments amplified. Oliveira et al (2014), evaluating the genetic distance among 37 accesses of Psidium spp., using 17 primers, obtained 216 polymorphic fragments, with an average of 13 by primer. Studying the diversity of 272 genotypes of the same species of the jaboticabeira family, Myrcia splendens (SW), Brandão et al (2011) used 10 primers and identified 70 polymorphic fragments.…”

ABSTRACT-The jaboticaba tree (Plinia sp.) is a native fruit tree belonging to the Myrtaceae family, which occurs spontaneously throughout Brazil. The estimation of genetic divergence among genotypes of native populations can be useful for conservation and knowledge of available genetic resources, in the formation of gene banks and breeding species. In order to evaluate the genetic diversity of jaboticaba trees identified in the Bahia Reconcavo municipalities, 35 genotypes were characterized by ISSR primers (Inter Simple Sequence Repeats). The 18 primers generated a total of 463 amplicons, and the number of initiator fragments ranged from 14 to 36, with an average of 25.72% and 99.65% polymorphism. Polymorphic information content ranged from 0.13 to 0.33 with a mean of 0.22 and the marker resolution power from 4.34 to 15.77, with an average of 8.67. Multivariate analysis allowed the formation of five groups of genetic divergence, where the longest distance was 0.97 between JCA6 and JSF8 genotypes and the lower of JMT2 and JCA1 (0.11). From the use of ISSR markers it is possible to check the variability between genotypes on the evaluated jaboticaba trees. Index terms: genetic diversity, ISSR, Plinia sp.
