Nina Ratna Djuita, Alex Hartana, Tatik Chikmawati, Dorly. 2020. Genetic Diversity of Pulasan [Nephelium ramboutan-ake (Labill.) Leenh.] of Java Based on SSR and ISSR Markers. 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. Keanekaragaman Genetik Kapulasan [Nephelium ramboutan-ake (Labill.) Leenh.] di Jawa Berdasarkan Marka SSR dan ISSR. Floribunda 6(4): 117–126. —  Kapulasan merupakan salah satu buah lokal yang potensial untuk dikembangkan. Penelitian ini bertujuan untuk menganalisis keanekaragaman genetik kapulasan di Jawa dengan menggunakan marka Simple Sequence Repeat (SSR) dan Inter Simple Sequence Repeat (ISSR) serta untuk mendapatkan informasi apakah primer dari marka tersebut dapat dipakai untuk membedakan tumbuhan jantan dan hermafrodit.  Hasil penelitian menunjukkan bahwa dua primer pada marka SSR dan tujuh primer pada marka ISSR menghasilkan pita polimorfik. DNA genom kapulasan yang diamplifikasi dengan  marka SSR menghasilkan pita-pita dengan ukuran 110–500 bp, sedangkan dari marka ISSR berukuran 150–1500 bp. Populasi kapulasan di Babakan Madang mempunyai keanekaragaman genetik paling tinggi, sedangkan populasi di Patean paling rendah. Variasi genetik kapulasan berdasarkan  marka SSR dan ISSR di dalam populasi dan di antara populasi mempunyai komposisi yang berbeda. Variasi di dalam populasi sebesar 72 % sedangkan di antara populasi sebesar 28%. Primer LML Y6 dan LML Y12 dari marka SSR dan primer ISSR 2, 3, 4, 5, 6, 8, 9  tidak dapat digunakan untuk membedakan tumbuhan kapulasan jantan dan hermafrodit.

Among ten slow-growing protoclones of Agaricus bisporus (J. Lge) Imbach, all appressed colonies showed slower growth rate and spawn run, and inability to produce fruiting bodies in substrate. Seven of 40 inter-simple sequence repeat (ISSR) primers amplified 78 reproducible fragments, 48.93% were polymorphic, each producing 7 to 16 bands ranging from 0.10 to 2.10 kbp, sufficient to differentiate the protoclones from each other. Appressed protoclones were homoallelic at a number of loci that were heteroallelic in the parent, suggesting that they represented rare homokaryons. Thus, using morphological characters along with ISSR, polymorphisms could be useful for quick, easy, and accurate in distinguishing homo- and heterokaryotic isolates. Key words: Agaricus bisporus (J.

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.
