“…Grouping pattern not only discriminated the state of origin of guava accessions but also helped to identify candidates for further breeding programs in Vietnam which may target separately or simultaneously higher fruit weight, less seed number and aromatic trait. Similar recommendations were reported in previous studies employing morphological traits as measures to estimate the diversity and explore the possibility of exploiting the desirable variability in guava accessions worldwide (Rajan and Yadava 2012, Mehmood et al 2014, Pérez Pelea et al 2016, Kareem et al 2018.…”

Background: Guava (Psidium guajava L.) is an important cultivated fruit crop in Vietnam due to its commercial value for fresh consumption and especially for fruit processing industry. A large number of diverse guava accessions, both indigenous and exotic, are available in Vietnam but their characterization, which is needed to identify targeted guava accessions for breeding programs, is still limited.Methods: The phenotypic variation and relationship among 40 guava accessions collected across Vietnam were assessed employing leaf and fruit morphological and physiological characterizations.Result: Range of variation for different leaf and fruit parameters were recorded. Significant correlations between leaf and fruit traits relating to yield and fruit quality were also observed implying a possibility of their simultaneous or interchangeable use in selection. Furthermore, the dendrogram generated from agglomeration hierarchical clustering grouped the 40 guava accessions into four major clusters which are highly associated with their origins. The result indicated that existing guava accessions are an important source of genetic diversity and can be used in the guava improvement program in Vietnam.

“…In a genetic characterization study of guava accessions from different municipalities in Pakistan for germplasm formation, Kareem et al (2018) found 85 alleles from 18 SSR primers, with an average of 4.7 alleles per locus-a high number when compared with the one found in this study. Costa and Santos (2013) analyzed genetic variability through 13 SSR in Psidium accessions from the Embrapa Semiárido germplasm bank and found the total of 183 alleles.…”

“…They are https://doi.org/10.1590/ 1678-4499.20210267 abundant in the genome, multiallelic and easy to automate, in addition to being affordable (Turchetto-Zolete et al 2017). SSR are also widely used in different countries as an efficient tool for the characterization of germplasm and in the study of genetic diversity in different Psidium species (Kareem et al 2018).…”

Brazil is one of the world's largest producers of guava (Psidium guajava L.), a very promising fruit in the northern region of the state of Rio de Janeiro. Despite this, no guava cultivar has been developed for the region. Thus, this study proposed to examine a population of guava full sibs using microsatellite markers and to identify which genotypes are the most divergent for future crosses, to select cultivars better adapted to the soil and climatic conditions of northern Rio Janeiro. Ninety-six superior genotypes were selected according to their agronomic traits, which were characterized using 45 microsatellite markers. The genetic distance between the analyzed genotypes, their clustering pattern and the genetic structure of the population were estimated. Hierarchical cluster analysis by the neighbor joining method indicated the formation of three distinct groups. The use of molecular information revealed the existence of moderate genetic variability between the genotypes of the full-sib families. Bayesian analysis separated the genotypes into only two groups, as the individuals shared most of the analyzed genomic regions. The most genetically divergent guava genotypes, that is, those allocated to different groups, such as genotypes 5 and 85, should be recommended for future crosses to obtain segregating populations, thus giving continuity to the guava breeding program.

“…The taxonomist's attention to the leaves' size comparison begins with the theory stating the shapes are not affected by the environment (Balduzzi et al 2017) and the venation is derived genetically (Dickinson et al 1987;Mishra et al 2010). Due to the availability and variations, the leaf is organ-rich information and the source of taxonomy data (Kareem et al 2018;Masungsong et al 2019). Leaf venation is also used to delineate between two confusing Dipterocarpaceae species in the same genera (Mazo and Aribal 2020).…”

Abstract. MeinataA, Na’iem M, Adriyanti DT, Syahbudin A. 2021. Short communication: Leaf architecture of 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes in Carita, Banten, Indonesia. Biodiversitas 22: 2952-2960. Dipterocarpaceae is a major commercial timber characterized by high unbranched bole, paired stipules, and winged fruit. The identification process in the family becomes problematic, in cases where the generative organ is absent. Therefore, a new approach needs to be established to address any misidentification leading to improper utilization. This study aims to determine the leaf architecture in 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes (KHDTK) Carita, Banten, Indonesia. The ten leaf samples collected were the third and fourth leaves from terminal shoots of a single tree of each species. Subsequently, the data were observed and measured based on the 17 morphological characters. Each character was then scored and analyzed using multivariate analyses cluster to determine the relationship between species. Dipterocarpaceae generally has pinnate leaf category, geniculate petiole, and entire margin. Furthermore, the phenon line in the dendrogram is cut at 0.695 similarity level to establish meaningful interpretation. The 35 species observed were grouped into 4 major clusters. Small leaf group, inconsistent tertiary vein pattern group, symmetrical leaves with cordate base leaf group, and other groups that do not resemble mentioned characters. The key determination comprised 34 couplets with three characters repeated due to limited descriptors.
