“…Although Cayetana Blanca displayed only one of the parental alleles at three loci, the authors posited the presence of null alleles which would still make the cross feasible. Geographical and historical reasons also supported the parentage hypothesis: Antão Vaz is the most important wine white cultivar cultivated in the Alentejo region, around Virgueira, Portugal (Almadanim et al 2007, Lopes et al 2006. Rabo de Ovelha is a white grapevine which at present is found throughout Portugal (Lopes et al 2006), but it probably originated from the Alentejo region (Almadanim et al 2007).…”

“…AlentejoBadajoz, a region in the southwest Iberian Peninsula, has been suggested as the probable place of origin of Cayetana Blanca (Lopes et al 2006). In Morocco, the name for Cayetana Blanca is Djinani and is also considered a local variety.…”

“…Twenty-eight SSR markers were used to provide evidence that Cayetana Blanca was the progeny of a cross between Antão Vaz and Rabo de Ovelha (Lopes et al 2006). Although Cayetana Blanca displayed only one of the parental alleles at three loci, the authors posited the presence of null alleles which would still make the cross feasible.…”

“…Cayetana Blanca has been identified as an offspring of a cross between Antão Vaz and Rabo de Ovelha using data obtained for 28 microsatellite loci (Lopes et al 2006). Although they detected incompatibilities at three loci, the authors argued that the possible existence of null alleles would explain those incompatibilities.…”

Cayetana Blanca is a grapevine variety widely distributed in the Iberian Peninsula (Spain and Portugal). Its numerous synonyms and its presence in northern Africa point to a long history of cultivation. The goal here was to identify the genetic relationships of Cayetana Blanca with other Iberian and Mediterranean cultivars using a panel of SNP markers. A total of 243 single nucleotide polymorphisms (SNPs) and four chloroplast microsatellite loci allowed for identifying synonyms and trio (parents and offspring) and duo (parent-offspring) relationships. Six trios including Cayetana Blanca as a parent were found and supported by very high LODs. Five of the trios had the variety Alfrocheiro Preto as the other parent and gave rise to cultivars used in Portugal: Cornifesto, Camarate, Mouratón, Malvasia Preta, and Periquita. The Spanish cultivar Jaén Tinto is confirmed to be an offspring of Cayetana Blanca and Listán Prieto. Additionally, synonyms and duos were detected that, in some cases, were not anticipated. The parents of Cayetana Blanca remain unknown, while the geographical origin of Cayetana Blanca could be a border region between Portugal and Spain. Results show that this cultivar has had a relevant impact in the viticulture of that area. As in other European regions, viticulture in the Iberian Peninsula is also marked by the impact of certain varieties that have worked as progenitors of many present cultivars. The results also show the interconnection between Portuguese and Spanish viticulture. Finally, the study demonstrates that SNP is a powerful tool for parentage inference in grapevine.

“…Park et al (2013) reported that 41genotype-specific alleles were identified for 12 of 14 SSR markers. Sun et al (2009) used seven SSR markers to study genetic diversity and discriminate among recently distributed rice accessions and Lopes et al (2006) used 11 SSR markers to discriminate among 46 Portuguese grapevine accessions. Euclidean distances based on the 1-0 matrix of microsatellite markers were taken into account to study the relationship between the diverse sesame germplasm accessions.…”

Sesame is an important ancient oilseed crop of high medicinal value. In the present study, 37 characters including both quantitative and qualitative traits of sixty genotypes were characterized following IPGRI morphological descriptors for sesame. Multivariate analysis was computed to distinguish the varieties into different groups. Though thirty six microsatellite markers including genomic and Est-SSR markers were initially selected, but, finally, the accessions were genotyped by eight polymorphic primers. Altogether, 27 alleles were detected among the 60 genotypes, with an average of 3.37 alleles per locus. The number of alleles ranged from 2 to 6 alleles. From data of microsatellite markers, dissimilarity coefficients between varieties were computed following Jaccard's coefficient method. Principal co-ordinate analysis was used to represent the varieties in bi-directional space. Dendrogram was constructed using NJ method based on dissimilarity matrix. Cluster analysis based on morphological and molecular marker classified sesame genotypes into two major groups. Mantel test showed an insignificant correlation between phenotypic and molecular marker information. The genotypes belonging to the same geographical area did not always occupy the same cluster. The results confirmed that both genetic and phenotypic diversity in a combined way could efficiently evaluate the variation present in different sesame accessions in any breeding program.
