“…Therefore, the application of molecular markers to assist the pre-breeding and breeding processes is highly desirable to accelerate varietal selection and genetic gain.DNA markers are known to be highly efficient in diversity assessment of plant species (Yildiz et al, 2021). DNA analysis can be performed with only small amounts of material from any part of the plant, and markers are independent of environmental conditions and plant phenological stages (Lande and Thompson, 1990;He et al, 2014).…”

The development of cashew orchards increased in recent years in Burkina Faso, due to high nut demand on international markets. However, little activities have been oriented toward cashew cultivar development, and farmers often use seed plants with little or no information about genetic characteristics of the material at hand. Therefore, a description of cashew diversity is needed to provide guidance to farmers and identify elite material for the crop improvement. In this study, phenotypic attributes of cashew accessions collected in Western Burkina Faso were recorded. Then, Gower's distance was used to show phenotypic relationship among accessions. Furthermore, four microsatellite markers were used to assess the genetic diversity of accessions, based on amplicon sequences. Sequence patterns across samples were converted into 75 binary alleles, combining sequence length and nucleotide polymorphisms. The 75 binary markers were 100% polymorphic and provided high average alleles per primer of 18.75. The polymorphic information content (PIC) varied between 0.003 and 0.895, averaging 0.534 per primer. Gower's distance between cultivars varied between 0.151 and 0.894. Dendrograms based on Nei's distance and Gower's distance revealed three main clusters each, although group compositions were different. These results were discussed with an outlook on future cashew tree breeding in Burkina Faso.

“…fruit; pomegranate, molecular markers, regression analysis During the past years, molecular markers based on DNA have been widely used for various purposes in fruit trees, including sour cherry (Yaman, 2022), apricot , walnut (Yildiz et al, 2021), and banana (Pinar et al, 2019). Constant progress in improving plant species breeding depends on the genetic diversity of plants.…”

Pomegranate (Punica granatum L.) is very important in terms of horticulture and food around the world. The present research aimed to identify the random amplified polymorphic DNA (RAPD) markers associated with morphological traits in pomegranate genotypes. Significant differences were observed among the studied genotypes based on the recorded traits. The 18 RAPD primers produced a total of 154 polymorphic fragments among genotypes. Using multiple regression analysis between each of the morphological traits and 154 RAPD polymorphic bands, RAPD markers associated with each of the morphological traits were identified. In total, 11 markers showed significant correlations with fruit weight, 9 markers with 100‐aril weight, 11 markers with anthocyanin, and 8 markers with total soluble solids. Some markers were associated with more than one morphological trait, showing that the association of a marker with more than one trait can be caused by the pleiotropic effects of quantitative trait loci related to each other in different traits. For instance, the BA6‐1 marker showed positive correlations with fruit weight, fruit crown width, and leaf length. Also, OPG13‐3 and BA6‐10 markers showed positive correlations with total soluble solids and anthocyanin content. The informative markers identified related to morphological characteristics in pomegranate can be a suitable guide to identify the genotypes with valuable fruit traits. Also, these markers can be used in selecting suitable parents for population generation for mapping purposes.

“…Turkey is not the homeland of the bean, but several studies have indicated the existence of wide variation among local bean local varieties in Turkey [ 9 ]. The characterization of local varieties provides an opportunity to determine genetic diversity and to identify new variations that can be used in various breeding programs [ 10 , 11 , 12 , 13 , 14 ].…”

Beans are legumes that play extremely important roles in human nutrition, serving as good sources of protein, vitamins, minerals, and antioxidants. In this study, we tried to elucidate the genetic diversity and population structure of 40 Turkish bean (Phaseolus vulgaris L.) local varieties and 5 commercial cultivars collected from 8 different locations in Erzurum-Ispir by using inter-primary binding site (iPBS) retrotransposon markers. For molecular characterization, the 26 most polymorphic iPBS primers were used; 52 bands per primer and 1350 bands in total were recorded. The mean polymorphism information content was 0.331. Various diversity indices, such as the mean effective allele number (0.706), mean Shannon’s information index (0.546), and gene diversity (0.361) revealed the presence of sufficient genetic diversity in the germplasm examined. Molecular analysis of variance (AMOVA) revealed that 67% of variation in bean germplasm was due to differences within populations. In addition, population structure analysis exposed all local and commercial bean varieties from five sub-populations. Expected heterozygosity values ranged between 0.1567 (the fourth sub-population) and 0.3210 (first sub-population), with an average value of 0.2103. In contrary, population differentiation measurement (Fst) was identified as 0.0062 for the first sub-population, 0.6372 for the fourth subpopulations. This is the first study to investigate the genetic diversity and population structure of bean germplasm in Erzurum-Ispir region using the iPBS-retrotransposon marker system. Overall, the current results showed that iPBS markers could be used consistently to elucidate the genetic diversity of local and commercial bean varieties and potentially be included in future studies examining diversity in a larger collection of local and commercial bean varieties from different regions.
