“…The success of a breeding program cannot be apart from the genetic diversity of germplasm used and the relationship between accessions to be used as a parent. Based on the analysis, it was found that the genetic diversity of 26 sapodilla in DIY was high (h = 0.2854 ± 0.1490) which is in accordance with Hu et al (2014) who reported that perennial plants (out-crossing) had a great diversity. According to this research, sapodilla selection based on locationis more effective due to the tendency of sapodilla accessions in DIY to be clustered according to geographical location.…”

The objective of this research was to determine the diversity and relationship of sapodilla accession derived from districts in DIY based on DNA profiles. From the screening of 20 total primers, five primers (OPA 20, OPB 5, OPB 6, OPB 8, and OPC 19) producing polymorphic bands in RAPD analysis were selected. Different-shaped samples of sapodilla randomly collected from Bantul, Gunungkidul, Kulonprogo, Sleman and Yogyakarta city were used in this research. The analysis of molecular data was performed by using NTSys pc-2.02 and GenAlex 6.1 program. The clustering indicated that the accessions tend to group by their locations. However, there was no corelation between DNA marker and the fruit shape. The first group comprised samples from Yogyakarta city (Keraton Yogyakarta), Bantul and Kulonprogo while the second group consisted of samples from Sleman and Gunungkidul with genetic similarity of 53% and 37% respectively. The genetic diversity was high (PLP = 98.85% of 87 loci and H=0.280±0.14) comprising the genetic diversity within population (53%) which was greater than genetic diversity between populations (47%). Having the highest genetic diversity, Gunungkidul should be potential for conservation and selection of sapodilla in DIY.

“…Genetic diversity in plants is influenced by the breeding system, seed dispersal, genetic drift and evolutionary history. The habitat has a highly important influence on genetic diversity (Hu et al, 2014). Regarding the polymorphic information content (PIC), Botstein et al (1980) defined this parameter as highly informative (PIC greater than 0.5); reasonably informative (PIC between 0.25 and 0.50); and slightly informative (PIC values less than 0.24).…”

Genetic diversity in passion fruit plants at different altitudes

et al. 2019

Passion fruit belongs to the Passifloraceae family and to the genus Passiflora, which is economically relevant. This genus is originated from Brazil, which has the greatest genetic diversity. The altitudinal gradient may influence the distribution of genetic variation in and between plant populations and genetic diversity may change according to the altitude. The objective of this study was to evaluate the genetic diversity in passion fruit in different altitudes of Espírito Santo, using microsatellite markers (SSR) and inter simple sequence repeat (ISSR). Five matrixes plants of each species of Passiflora edulis Sims f. flavicarpa Degener, P. edulis Sims and P. alata Curtis were studied at three altitudes (low, medium and high) in the state of Espírito Santo. For each sample, 13 microsatellite markers developed for Passiflora edulis and 14 ISSR primers were amplified according to the greatest number of polymorphic fragments and amplification quality. Low values of alleles were found (1-3), and low heterozygosity was expected and slight PIC values were found, while for the ISSR analysis a large number of bands per primer were detected and high polymorphism. The P. alata Curtis species was the most divergent to P. edulis Sims f. flavicarpa Deg. and P. edulis Sims. The SSR and ISSR markers enabled us to indicate differences among the species, but they did not always show variation between and within similar species. The populations of low altitude are different from the others, independent of the species and the marker used. The habitat has a highly important influence on genetic diversity.

“…It means that the genetic diversity of those cultivars was in the range between 42% and 66%. Genetic diversity of a species within a population is the consequence of its sexual reproduction (Hu et al 2014;Pereira et al 2015). Genetic diversity of Lai was considered in high diversity because Lai is a cross pollination crop and commonly propagated using open pollinated seeds derived from random mating among Lai genotypes.…”

Abstract. Handayani F, Rahayu SP. 2017. Assessment of genetic diversity in Lai (Durio kutejensis) local cultivars of Batuah . Lai is an indigenous germplasm of Kalimantan which has potency to be developed as superior tropical fruit. Lai has attractive flesh color from yellow to reddish orange which represents the high content of carotene with smooth aroma or odorless fruit, and fruit storage period which longer than durian. Unfortunately, nowadays there is limited scientific information about its genetic diversity as important basic information for genetic conservation and breeding program. Batuah village in Kutai Kartanegara District is one of the center of origin and center of diversity of Lai in East Kalimantan, Indonesia which has many local cultivars with superior traits. The aim of this research was to study the genetic diversity of eight Lai local cultivars of Batuah village using molecular marker of ISSR. The total genomic DNA of eight Lai cultivars was isolated and was then used as template in the PCR amplification reaction using 10 ISSR primers. The result shows that similarity coefficient of eight Lai cultivars ranged between 0,34 and 0,58. Seven cultivars were grouped in the same cluster with 0,44 of similarity coefficient, while Lai Durian was separated in 0,34 of similarity coefficient. Genetically, the most similar existing cultivars are Lai Kuning and Lai Belimbing with the similarity coefficient of 0,58.
