Summary: This study evaluated the genetic diversity and population structure of 135 autotetraploid potatoes using SLAF-seq methods. Analysis of 3,397,137 high-quality SNPs revealed that the classification of these potatoes based on SNP profiles did not correlate with their geographical origins. Furthermore, 71 PARMS-SNP markers were successfully used to analyze 190 autotetraploid potato varieties. Overall, these novel SNP markers provide a solid foundation for potato genetic diversity analysis, DUS testing, and plant variety protection.

Summary: A study on the genetic diversity and population structure of 16 coconut accessions from the International Coconut Genebank for South Asia and the Middle East (ICG-SAME) in India revealed high genetic diversity. The analysis used 35 SSR loci and found that the accessions exhibited different numbers of alleles, indicating potential for marker-assisted selection in coconut.

Summary: Genomic characterization of 50 phenotypically variable apricot accessions using SSR markers revealed genetic variability and associations among accessions. The results showed an average number of alleles per locus of 3.89, effective number of alleles per locus of 1.882, and polymorphic information content values ranging from 0.464 to 0.104.

Summary: This study evaluated the genetic variation and migration rate of giant honey bees Apis dorsata from two districts in Punjab, Pakistan at the molecular level. The results showed low genetic variation within and between the populations of A. dorsata from Nankana and Narowal, with a small level of migration. Further genetic investigations are needed to preserve the biodiversity of these endemic races of honey bees in the region.

Summary: Determining the appropriate parents for breeding programs is crucial for plant breeders to maximize genetic variability and produce desirable genotypes. In this study, five kalanchoe genotypes were morphologically characterized and molecularly analyzed. The results showed distinct traits in different genotypes, such as plant height, number of inflorescences, flower length, and flower diameter. Cluster analysis based on morphological and molecular data revealed different clustering patterns. The study concluded that orange, violet, and yellow kalanchoe are suitable parents for breeding economically valued traits in kalanchoe. SCoT and RAPD markers were found to be reliable tools for assessing genetic polymorphism among kalanchoe genotypes.

Summary: This study assessed the genetic diversity and population structure of 90 cowpea accessions using SNP markers. The results showed that cowpea has high tolerance to heat and drought stresses, making it important for improving crop production resilience. The study also revealed low genetic diversity and high homozygosity among cowpea accessions.

Summary: Understanding the genetic variation and differentiation of natural populations is crucial for the protection of endangered species like Pinus bungeana. The study analyzed genetic diversity, genetic structure, phylogeny, and geographical differentiation of 52 individuals from 5 populations. The results showed a decrease in genetic diversity from west to east and the presence of significant genetic differentiation among populations due to geographic isolation. The findings provide valuable information for in situ and ex situ conservation strategies for P. bungeana.

Summary: Our study utilized AFLP markers to assess the genetic variations and identify different M. sagu populations in Sarawak. We obtained polymorphic fragments and assessed their information content, marker index, and resolving power. The results showed that Mukah had higher diversity compared to Pusa, and a significant positive correlation was observed between genetic divergence and geographical distance. Our study highlights the effectiveness and reliability of AFLP markers for studying genetic variations and identifying M. sagu.

Summary: In this study, 150 SNP markers were developed and used to evaluate the genetic diversity of 84 litchi accessions. The newly developed SNP markers captured a relatively higher level of genetic diversity and could be successfully applied for the identification of synonymous cultivars and hybrids. The study also found a clear association between fruit maturation period and genotype clusters.

Summary: In this study, 20 wheat lines were evaluated for morphological and genetic diversity using eight simple sequence repeats markers from Wheat Microsatellite Consortium (WMC). Variations were observed among the wheat lines for most of the studied traits. Genetic diversity analysis revealed the presence of 16 alleles at eight SSR markers, with an average of 2.00+/-0.534 alleles per locus. The highest number of alleles was observed for marker WMC78, and genotypes AC and AA were predominantly found in high-yielding lines Borlaug-2016 and Zincol-2016.

Summary: AFLP analysis revealed genetic polymorphism among wabisuke camellia and its relative species, suggesting the two old 'Uraku' trees are asexually-propagated clonal strains. The genetic distance between wabisuke cultivars and Chinese camellias was greater than that between wabisuke cultivars and Camellia japonica. Wabisuke camellias can be classified into two subgroups based on their genetic characteristics.

Summary: This study used genotyping-by-sequencing (GBS) to identify novel SNP markers and characterize 288 finger millet accessions from Ethiopia and Zimbabwe. The analysis revealed potential candidates for breeding and significant genetic differentiation among accessions based on geographic proximity, country of origin, days to flowering, panicle type, and Al tolerance, suggesting the potential for developing superior cultivars through the recombination of genetically distinct accessions.
