“…As it was noticed that cross-pollinated flowers would also produce seedless fruits, therefore ways to initiate seeded fruits need to be found out to increase genetic diversity (Ragone 2001). According to Bhandari et al (2017), evolutionary abilities such as selection, mutation, and migration can produce changes in allelic frequencies in a population and affect genetic diversity. As Bawean Island is seen as native area of the breadfruit plants in Indonesia, it needs to be thoroughly investigated through genetic markers to find out novel lines of breadfruit for their breeding and conservation of germplasm.…”

Abstract. Rahmah W, Waluyo B. 2019. Genetic distance and diversity of breadfruit (Artocarpus altilis) based on morphological characters in Bawean Island, Indonesia. Biodiversitas 20: 3284-3291. One of the ways to preserve species germplasm is by identifying the genetic distance and intraspecific diversity. The aims of this study were to study the distribution and cultivation status, genetic distance, and diversity of breadfruit plants, Artocarpus altilis (Parkinson ex F.A.Zorn) Fosberg, in Bawean Island, Gresik, Indonesia based on morphological characters. The study made 30 accessions of breadfruit plants spread throughout Bawean Island, which were found to be neither cultivated intensively nor used optimally by the inhabitants. The genetic distance showed that breadfruit in Bawean Island was clustered into 6 groups with similarity coefficient of around 0.9984 to 0.9999. The diversity index value of 1.48 indicated medium diversity of breadfruit on this island.

“…The increasing age of coconut fruit then the fatty acid content will increase and water content decreases. Bawalan (2005) which stated that the fatty acid content of coconut meat is influenced by several factors such as coconut type and variety, coconut age, climate, soil type and altitude. The land suitability class for coconut plantations is basically based on the horizon where the coconut plants will be planted, the physical properties of the soil, and the ability of the soil to retain water.…”

“…These were naturally occurring variants of a particular plant species. Later, cytological and biochemical differences occurring in the genotypes of a species started to be used in genetic diversity assessment (Bhandari et al 2017). These analyses are carried out by raising germplasm lines, pure lines, B I O D I V E R S I T A S 20 (11): 3413-3421, November 2019 3414 improved varieties, etc.…”

Abstract. Siregar LAM, Damayanti R, Hanafiah DS. 2019. Variability of coconut phenotype based on morphology and content of fatty acids in Asahan District, North Sumatra, Indonesia. Biodiversitas 20: 3413-3421. A study that aims to determine the diversity, relationship and fatty acid content in several coconut genotypes (Cocos nucifera L.) grown and cultivated in Asahan District of North Sumatra Province, Indonesia was investigated. The coconut was obtained from the Air Joman and Silau Laut subdistricts of Asahan District, between April and September 2017. This study used morphological observation method based on IPGRI (International Plant Genetic Resources Institute) coconut descriptor with purposive sampling technique. A total of 36 coconut genotypes have been collected and identified based on morphological characters and fatty acid content. Based on the morphological character, the genotype of G28 and G32 show the closest relationship with the dissimilarity value of 3.00 and the farthest relationship on the genotype of G40 and G43 with the dissimilarity value of 12.04. Based on the 10 main type fatty acids found in coconut oil, all genotypes have between 8 and 10 types of fatty acids, i.e. caprylic, capric, myristic, palmitic, stearic, oleic, linoleic and arachidic acid in the oil. The average amount of fatty acid contained in coconut oil obtained generally in other coconut oil. Genotype of G5 has the highest content of lauric acid and has 12.1 mm thick flesh, but only 8 types of fatty acid composition are present in the oil.

“…Molecular markers are valuable tools for discrimination between accessions, easy and cost-effective to measure and not influenced by environmental factors. Microsatellites (SSR) markers have efficient advantages over other DNA markers that they are highly polymorphic, co-dominant inheritance with high mutation rates, relatively abundant and good genome coverage, which used to investigate taxonomical, genetic diversity and evolutionary relationship [17,18]. However, SSR markers have limitations such as genomic sequencing is needed to design specific primers; it is also not very costeffective and requires much discovery and optimization for each species before use [19].…”

Background: Vernonia (Vernonia galamensis) is a potential novel industrial crop due to high demand for its natural epoxidized oil, which can be used for the manufacturing of oleochemicals such as paints, plastic formulations (polyvinyl chloride), and pharmaceutical products. This study was initiated for the systematic and intensive genetic diversity assessment of V. galamensis accessions by SSR molecular markers to minimize the existing research gaps, provide a clue for germplasm conservation and further research. Results: Twenty SSR markers were used for genetic diversity analyses of 150 individual V. galamensis accessions representing 10 populations, from which a total of 79 bands were identified for the 20 loci. All the loci used showed high polymorphism that ranged from 0.50 to 0.96, while the mean observed heterozygosity (Ho) was 0.15 across all the 20 markers evaluated. The molecular variance analysis (AMOVA) showed significant variations among populations which accounted for 11% of the variations. Populations clustering showed that the dendrogram and principal coordinate’s analysis roughly classified the accessions into four groups. However, the Bayesian model-based clustering (STRUCTURE) grouped into 6 (K = 6) major gene pools. Since, the cluster and the STRUCTURE analyses did not group the populations into sharply distinct clusters, due to presence of gene flow and mode of reproduction of the plant. Conclusions: The SSR molecular markers used in this study are highly polymorphic. Among the ten populations, East Showa and East Hararghe revealed higher genetic diversity, signaled that these areas are the hotspots for in-situ conservation of V. galamensis. In addition, the values of SSR markers such as heterozygosity, Shannon‘s index, polymorphic information content, and population clusters are important baseline information for future V. galamensis cultivation, breeding and genetic resource conservation endeavors in Ethiopia.
