Inter simple sequence repeat (ISSR) markers were used for variation analysis among 41 tomato accessions. A total of 50 scorable bands were obtained, where 32 were polymorphic, representing 63.3% of all the amplified loci. Polymorphism percentage ranged from 50 to 90% and an average number of polymorphic bands of 4.0 were observed. An average genetic diversity index was 0.61. Primer UBC860 and UBC825 generated the greatest diversity index with a value of 0.89 and 0.85 respectively. The smallest diversity identified by primer UBC808, with an index of 0.34. The genetic similarity among studied genotypes ranged from 0.52 to 0.98. The cluster analysis based on Jaccard?s similarity coefficient divided genotypes into 6 distinct clusters on a value of 0.74. The lowest genetic distance was found between ?Gronastiy? and ?AG1224? (0.52), ?Orange? and ?AG1224? (0.54), and ?Evgeniya? and ?AG1224? (0.55) accessions. The highest similarity of 0.98 was determined between ?Zafar? and ?Azerbaijan-94?, ?Khachmaz-1? and ?Azerbaijan-94?, ?Khachmaz-1? and ?Severyanka?, and ?Shakar? and ?Absheron-1? accessions.

Floribunda 6(4): 117–126. —  Pulasan is one of the potential local fruits to be developed. This study aimed to analyze the genetic diversity of pulasan of Java using Simple Sequence Repeat (SSR) and Inter Simple Sequence Repeat (ISSR) markers and to obtain information whether primers of the markers could be used to distinguish male and her-maphrodite plants. The results showed that two primers in the SSR markers and seven primers in the ISSR markers produced polymorphic bands. The genomic DNA of the pulasan amplified with SSR markers produced bands 140–500 bp, while those from the ISSR markers were 150–1500 bp. The population of pulasan in Babakan Madang has the highest genetic diversity, while that of Patean is the lowest. Genetic variation of pulasan based on SSR and ISSR markers in the population and among populations have different compositions. Variation in the population is 72% while among the population is 28%. Primers of LML Y6 and LML Y12 from SSR markers and primers of ISSR 2, 3, 4, 5, 6, 8, 9 cannot be used to distinguish male and hermaphrodite pulasan plants. Nina Ratna Djuita, Alex Hartana, Tatik Chikmawati, Dorly. 2020.

Abstract Morinda (Rubiaceae) is considerably recognized for its multiple uses viz. food, medicine, dyes, firewood, tools, oil, bio-sorbent etc. The molecular characterization of such an important plant would be very useful for its multifarious enhanced utilization. In the present study, 31 Morinda genotypes belonging to two different species Morinda citrifolia and Morinda tomentosa collected from different regions of India were investigated using Inter Simple Sequence Repeat (ISSR) markers. Fifteen ISSR primers generated 176 bands with an average of 11.7 bands per primer, of which (90.34%) were polymorphic. The percentage of polymorphic bands, mean Nei’s gene diversity, mean Shannon’s information index in Morinda tomentosa and Morinda citrifolia was [(69.89%, 30.68%); (0.21 ± 0.19, 0.12 ± 0.20); (0.32 ± 0.27 0.17 ± 0.28)] respectively, revealing higher polymorphism and genetic diversity in Morinda tomentosa compared to Morinda citrifolia. Structure, and UPGMA cluster analysis placed the genotypes into well-defined separate clusters belonging to two species Morinda tomentosa and Morinda citrifolia revealing the utility of ISSR markers in species differentiation. Distinct ecotypes within a particular species could also be inferred emphasizing the collection and conservation of Morinda genotypes from different regions, in order to capture the overall diversity of respective species. Further higher diversity of M. tomentosa must be advanced for its utilization in nutraceutical, nutritional and other nonfood purposes.

In this study genetic diversity and interspecific relationships of 11 Allium L. species from Khorassan province of Iran including 32 accessions were investigated by inter simple sequence repeat (ISSR) markers. Nine ISSR primers produced a total of 80 polymorphic markers and revealed high polymorphism among the studied species. The average gene diversity, effective number of alleles and Shannon’s information index were 0.2, 1.28 and 0.3, respectively. Allium kuhsorkhense exhibited the greatest level of variation (He: 0.18), whereas A. stipitatum demonstrated the lowest level of variability (He: 0.05). UPGMA (Unweighted Pair Group Method with Arithmetic mean) analysis showed that Allium accessions have a similarity range of 0.60 to 0.95. Allium scapriscapum composed the most distant group in the dendrogram. The clustered groups of Allium species clearly reflect the recent taxonomic concept of the genus at the subgenus and section levels. The present study showed that the ISSR technique is an effective molecular approach for analyzing genetic diversity and relationship in Allium species.Bangladesh J.

Genetic diversity of 51 oil-tea camellia germplasms was analyzed using the optimized inter-simple sequence repeat (ISSR)–PCR reaction system with 22 primers screened from a set of 100 ISSR primers. The results showed that 493 discernible loci with distinct electrophoretic bands were obtained, of which, 478 loci (96.78%) were polymorphic. This indicated that oil-tea germplasms possess abundant genetic diversities. By clustering analysis performed using softwares of NTSYS 2.10 and Winboot, 51 oil-tea germplasms were divided into two groups: Group I had 48 lines of Camellia oleifera Abel, while Group II had three C. oleifera Abel related species and their similarity coefficient was 0.62. Group I was further divided into Group I-1 and Group I-2, and their similarity coefficient (Gs) was 0.634. All members of Group I-1 originated from Hunan Province, while Group I-2 included the rest of Hunan lines and those originated from other regions of China. Analyzed by software POPGENE 1.32, the Shannon's information index (I*) of genetic polymorphism was 0.3852, the genetic diversity among different region populations (Ht) was 0.2537, the genetic diversity within populations (Hs) was 0.15545, the differentiation coefficient of genetic diversity among populations (Gst) was 0.3967, and the gene flow among populations (Nm*) was 0.8262. The Nei's genetic distances between the Hunan population and the populations originated from other regions of China implied that geographic isolation strongly influenced genetic differentiation among populations. Meanwhile, seedling rootstock grafting and high grafting for tree crown produced genetic variations among clonal offsprings.

The goal of this study was to determine the level of genetic diversity and relatedness among 16 strawberry (Fragaria H ananassa Duch.) cultivars and 11 breeding lines developed in Canada, using Inter Simple Sequence Repeat (ISSR) markers. Seventeen primers generated 225 polymorphic ISSR-PCR bands. Cluster analysis by the unweighted pair-group method with arithmetic averages (UPGMA) revealed a substantial degree of genetic similarity among the genotypes ranging from 63 to 77% that were in agreement with the principal coordinate (PCO) analysis. Geographical distribution for the place of breeding program explained only 1.4% of total variation as revealed by analysis of molecular variance (AMOVA). The ISSR markers detected a sufficient degree of polymorphism to differentiate among strawberry genotypes, making this technology valuable for cultivar identification and for the more efficient choice of parents in current strawberry breeding programs. Key words: Fragaria × ananassa, DNA fingerprinting, multivariate analysis, breeding, genetic similarity
