“…da Silva et al (2015) reported that the numbers and frequencies of alleles in genetic diversity studies affect the marker heterozygosity. Compared to previous studies on the analysis of genetic diversity in Iranian grapes by microsatellite markers (Fatahi et al, 2003;Khadivi et al, 2017;Najafi et al, 2006;Ramezani et al, 2009), our results indicated higher He values. The large load of deleterious recessive mutations (Olmo, 1976) and habitat fragmentation and artificial selection pressure (Yaghuti et al, 2018) could be the reasons for higher Ho in this study.…”

“…Moreover, there is limited information about the genetic resources and variation of grapevine in Iran. For this reason, it is of high importance to study local grapevine varieties and genotypes from the supposed primary domestication area and investigate the genetic relationships and kinship (Khadivi et al, 2017). Ampelography and biochemical markers (polymorphism of proteins and anthocyanins) have been used in the last decades to identify different cultivars of grapevine (Crespan et al, 1999).…”

One of the most important requirements for cultivar identification in Vitis species is rapid and consistent genotyping using DNA-based markers. Genetic characterization and diversity of grapevine cultivars using molecular markers have been the subject of many studies. The Iranian grapevine biodiversity is one of the most important in the Middle East. In the present work, fourteen nuclear microsatellite markers were used to assess the genetic diversity and relationships among 25 local grapevine accessions collected from vine-growing areas of Qazvin province (Iran). A total of 81 distinct alleles were produced with amplified product sizes ranging from 91 to 432 bp. The number of observed alleles for each locus ranged from 2 (ISV3) to 9 (VVS3 and VVMD6), with the overall average of 5.79 allele per locus. The observed heterozygosity (Ho) ranged from 0.53 (ISV3) to 0.72 (VVSMD25), while the expected heterozygosity (He) varied between 0.49 (ISV3) and 0.87 (VVSMD25). The polymorphism information content (PIC) ranged between 0.50 for VVS3 and ISV3 to 0.87 for VVSMD25. However, Shannon's information index (I) was found to be highest (2.13) in VVSMD25 locus, while the VVS3 locus had the lowest value with an average of 0.75 among SSR markers. According to Jaccard's similarity coefficient and UPGMA algorithm, cluster analysis assigned the accessions into five groups. Despite similar names, the results revealed that the accessions belonged to different groups. The obtained PCoA scatter plots further strongly supported their UPGMA dendrogram results. Beside VVMD, VVS series of markers were also used in the present study and the results showed that these series of microsatellite markers were as efficient as VVMD series in terms of discrimination and polymorphism for studying grapevine cultivars. Among all the microsatellite loci, VVSMD25 (PID = 0.03, PIC = 0.87) was found to be the most informative among the accessions.

“…The climate of a particular place greatly affects the grapes' diversity and production of the crop (Akram et al, 2019). Globally, the knowledge of grape genetic resources has enormously increased the interests of scientists and researchers as germplasm is a valuable source for species conservation, understanding gene functions and development of new and improved lines (Khadivi et al, 2019;Ates et al, 2011;Khawale and Singh 2005). In grapes, ampelography is considered a scientific methodology to characterize grapes based on morphological, pomological and phenological traits (Ates et al, 2011).…”

This endeavor includes thirty grapes’ genotypes grown in northern zones of Punjab, Pakistan to determine similarities and dissimilarities in forty-four morphological traits according to the descriptor “International Plant Genetic Resources Institute (IPGRI)”. The relation between the genotypes was determined by principal component analysis (PCA), and similarity was worked out by using cluster analysis. The dendrogram divided the genotypes into two main groups with classes and subclasses. The variation present within the class was up to 81.72% while the difference between classes was 18.28%. The morphological quantitative traits such as bunch length, bunch width, bunch weight, peduncle length, the weight of 10 berries, number of berry in a bunch, berry length, and berry width were in the following range 27.50-11 cm, 13.75-5 cm, 583.56-77.70 g, 6.50-1.55 cm, 53.70-9.70 g, 354-28, 27.37-11.40 mm and 18.06-10.41 mm respectively, which indicated a wide level of diversity in the selected genotypes. Based on phenological attributes, “Regina”, “Perlet”, and “Early White” were found early maturing genotypes to prevent berry rotting due to monsoon rains at the final stage of ripening. The data generated in this study would be helpful to preserve the existing germplasm and be available for designing future breeding programs.

The management of germplasm banks is complex, especially when many accessions are involved. Microsatellite markers are an efficient tool for assessing the genetic diversity of germplasm collections, optimizing their use in breeding programs. This study genetically characterizes a large collection of 410 grapevine accessions maintained at the Agronomic Institute of Campinas (IAC) (Brazil). The accessions were genotyped with 17 highly polymorphic microsatellite markers. Genetic data were analyzed to determine the genetic structure of the germplasm, quantify its allelic diversity, suggest the composition of a core collection, and discover cases of synonymy, duplication, and misnaming. A total of 304 alleles were obtained, and 334 unique genotypes were identified. The molecular profiles of 145 accessions were confirmed according to the literature and databases, and the molecular profiles of more than 100 genotypes were reported for the first time. The analysis of the genetic structure revealed different levels of stratification. The primary division was between accessions related to Vitis vinifera and V. labrusca, followed by their separation from wild grapevine. A core collection of 120 genotypes captured 100% of all detected alleles. The accessions selected for the core collection may be used in future phenotyping efforts, in genome association studies, and for conservation purposes. Genetic divergence among accessions has practical applications in grape breeding programs, as the choice of relatively divergent parents will maximize the frequency of progeny with superior characteristics. Together, our results can enhance the management of grapevine germplasm and guide the efficient exploitation of genetic diversity to facilitate the development of new grape cultivars for fresh fruits, wine, and rootstock.
