“…The cophenetic correlation coefficient of the obtained dendrogram (r = 0.77) indicates a good adjustment between the genetic distances matrix and the dendrogram (TAO et al, 2014). Although the plants come from seeds, some showed little dissimilarity between them.…”

“…The most similar hybrid to the mother plant (H. undatus) was the L4P3-13 individual (0.54). Evaluating wild and cultivated accessions of the species H. undatus and H. polyrhizus Tao et al (2014) observed that the genetic distance ranged between 1.79 and 8.06, and the highest variation was obtained among cultivated accesses.…”

“…In order to characterize germplasm variability, the use of molecular markers such as RAPD (Random Amplified Polymorphic DNA) and ISSR (Inter Simple Sequence Repeats) have been widely used (JUNQUEIRA et al, 2010a;JUNQUEIRA et al, 2010b;TAO et al, 2014) however it is possible, through the description of morphological characteristics, to verify the variability of a set of plants. Pitaya presents great ecotypic diversity, and species can be defined according to the characteristics of cladodes, flowers and fruits (ORTIZ HERNÁNDEZ; CARRILLO SALAZAR, 2012).…”

“…So far, no morphological descriptors have been defined for E. acida; the descriptors proposed by the International Organizations for Succulent Plant Research (IOS) for other cactuses are inadequate according to Hoffmann and Walter (2004). Molecular markers are used because morphological traits are sensitive to environmental influence; these markers directly reveal polymorphisms at the DNA level and are a powerful tool to clarify genetic diversity and evaluate relationships among genotypes (Tao et al, 2014). Among these, the inter simple sequence repeat (ISSR) molecular markers are related to a genetic marker that allows obtaining levels of variation in genomic DNA fragments, particularly nuclear ones.…”

“…These regions consist of tandem repeats of simple patterns such as (CT)n or (CA)n located between non-repetitive sequences of the eukaryotic nuclear genome (Zietkiewicz et al, 1994). They are widely used for genetic diversity studies in many plants (Ferreira et al, 2010;Bianco et al, 2011;Almajali et al, 2012;Tao et al, 2014). However, no reports exist of their application in the germplasm of the species of the genus Eulychnia.…”

There are endemic cacti species in the North of Chile with edible fruits and a fledgling productive potential, with unknown degree diversity. Low diversity compromises the ability of populations to evolve and reduces their chances of survival under environmental changes. Copao (Eulychnia acida Phil.), a cactus endemic to Chile that grows in the Coquimbo Region (30º S lat) and able to bear fruit in water stress conditions, were morphologically characterized using descriptors of other columnar cacti at three different locations where it usually grows wild. Five inter simple sequence repeat (ISSR) primers, which were reported for other cacti that produced replicable and informative amplifications, were selected for the genetic characterization. Statistical analysis was performed to describe the diversity of this species and morphological and genetic results compared each other. High variation was observed between and within the evaluated populations for parameters of central tendency, dispersion, and univariate statistical analysis of the morphological traits. Principal component analysis showed that 73% of the population variation at the three locations could be explained by the first three principal components with 34%, 22%, and 17% of the observed variation, respectively. The five ISSR primers generated 7 to 11 polymorphic bands with a band range between 100 and 1517 bp. The polymorphic information content (PIC) averaged 0.75, which suggests high diversity between and within populations. Consensus of 85% existed between the selected descriptors and the ISSR markers, which points them out as suitable tools to analyze diversity in this species.K e y w o r d s : C o p a o , d e s c r i p t o r s , g e n e r a l i z e d procrustes analysis (GPA), genetic and morphological characterization, inter simple sequence repeat (ISSR).

Prunus salicina 'Shazikongxinli' is one of the most economically valuable and reputable Prunus salicina varieties in China. Understanding the genetic diversity and population structure of 'Shazikongxinli' is crucial for excellent germplasm breeding and conservation of genetic resources. In the present study, the genetic variation status of 50 'Shazikongxinli' was assessed using morphological traits, IRAP and ISSR markers, while 18 other plum varieties were selected as outgroups. The results show that the average Shannon-Weaver diversity index (H') of 32 qualitative traits in 50 test 'Shazikongxinli' is 0.557, the average coe cient of variation of 11 quantitative traits is 15.57%, and a total of 232 and 105 polymorphic loci are obtained from 22 IRAP and 15 ISSR primers, respectively. All three marker systems show relatively rich polymorphism, especially the IRAP markers.This may be related to the nature of the retrotransposons in the IRAP markers, which may be more suitable for intraspeci c variability detection than ISSR. In addition, all three markers cluster the 68-test germplasm into two groups, with all of 'Shazikongxinli' clustered into one group and most of the other plum varieties as outgroups clustered into another group. This suggests a relatively narrow genetic base within the current 'Shazikongxinli'. These results will be useful in understanding the genetic diversity of the germplasm resources of 'Shazikongxinli' and provide comprehensive information for the breeding of superior germplasm.
