Summary: The cacao tree is cultivated in the tropics to produce seeds, which are valuable raw materials for the chocolate industry. It is crucial to conserve and use cacao genetic resources for breeding programs to enhance yield, improve quality, and disease resistance. This review focuses on three important aspects of cacao genetics necessary for sustainable production and crop improvement: geographic distribution and genetic variation of wild cacao populations, conservation and utilization of cacao genetic resources, and genetic basis of agronomic traits and its application for cacao improvement. We also emphasize the critical research areas required for sustainable cacao cultivation.

Summary: The aim of this study was to assess the genetic diversity of European plum cultivars and hybrids in Lithuania using SSR markers. A total of 107 plum genotypes were evaluated, including 68 European plum cultivars and 39 hybrids, using nine microsatellite markers. Some genotypes had up to six alleles per locus due to the hexaploidy of plums. The number of alleles per primer ranged from 18 to 30, with an average of 24.33. Cluster analysis revealed that the European plum genotypes were grouped into eight clusters, unrelated to fruit color or shape. The European plum hybrids were grouped based on their pedigree.

Summary: This study evaluated the genetic diversity and structure of 24 A. chinensis populations and found high levels of genetic diversity in the polyploid populations. The study also revealed distinct eastern and western genetic clusters. Ecological niche modeling predicted a gradual loss of potentially suitable areas for tetraploids and increasing habitat fragmentation in the future.

Summary: Dragon fruits, economically important tropical fruits, belong to the family of Cactaceae and have evolved to adapt to arid environments. The draft genome of Hylocereus undatus was reported, revealing similarities in protein-coding genes with other Cactaceae plants and a whole-genome duplication event in their common ancestor. The genome also enabled the discovery of functional enrichment related to drought resistance and fruit flavor in dragon fruits.

Summary: Robusta coffee is an important source of income and employment for many developing countries. However, genetic erosion from the introduction of Congolese accessions threatens the genetic integrity of wild populations from the Guinean gene pool. Pollen from the Congolese gene pool shows greater ability to pollinate the Guinean group, necessitating conservation measures for wild populations.

Summary: Cacao is an important tropical crop, but the soils it grows in are often acidic and low in fertility. This study evaluated 60 cacao genotypes and found that early growth predictors of acid soil tolerance are the number of leaves and root area. Nutrient uptake, particularly for N, Ca, Mg, and K, may play a role in soil acidity tolerance. Ten genotypes were identified as potentially tolerant to soil acidity and could be used for breeding acid soil-tolerant cacao varieties.

Summary: This study focuses on the genetic structuring of Coffea canephora populations in Côte d'Ivoire using SNP markers. The results reveal the presence of two main genetic groups, Guinean and Congolese, and four subgroups within the Congolese group. Among the agronomic traits analyzed, the SG1 and SG2 subgroups displayed the highest performance. The findings highlight the importance of selecting the best progenitors within the Guinean group. This research provides valuable insights for future coffee breeding programs.
