RAPD analysis was carried out to determine genetic diversity that occurred among the selected accessions of H.elasticus obtained from six different hosts. All together 10 random primers were used for the RAPD assay, of which primer S11 produced 12 amplified bands in which 10 are polymorphic. Primer S9 produced the least number of amplified fragments. 10 primers together resulted in 88 amplified fragments, of which 26 are found to be polymorphic. Considerable polymorphism was shown by 3 primers that can be represented in a descending order S11>S79>S10. Accessions of H.elasticus obtained from Anacardium occidentale and Citrus maxima produced more polymorphic bands with S11. The overall polymorphism obtained in the selected samples of this hemiparasite was 29.54 indicating that genetic similarity was more among these samples rather than genetic diversity.

Metric Traits

Ten morpho-agronomic traits and 80 random amplified polymorphic DNA (RAPD) molecular markers were used to survey genetic diversity in 25 chickpea genotypes. Analysis of variance revealed significant variability among different genotypes for morpho-metric traits. The cluster analysis done using morpho-metric traits grouped 25 genotypes into seven and six clusters in Environment I (Env. I) and Environment II (Env. II), respectively. Three genotypes viz., ICCV-96904, HPG-17, ICCV-95503 and L-HR-1 belonging to diverse clusters were identified divergent and may use in heterosis breeding programme. Of 80 random RAPD markers, 25 were found polymorphic. Three major clusters were identified using 25 polymorphic RAPD markers. The genetic similarity coefficient among genotypes ranged from 0.57 to 0.91. The average polymorphic information content (PIC) for 25 RAPD markers ranges from 0.12 to 0.40. D2-statistic, RAPD analysis and study of genotypes performance revealed sufficient genetic diversity among chickpea genotypes which would be useful in future breeding programme.

Abstract Random Amplified Polymorphic DNA (RAPD) analysis was carried out on 19 Azerbaijan tomato genotypes, both cultivars and local populations. A total of 26 amplified products were revealed by 6 primers. The genetic similarity among evaluated genotypes ranged from 0.188 to 1.000. The lowest similarity was observed between cultivars ‘Azerbaijan’ and ‘Shakar’ (0.188), while the highest between ‘Elnur’ and ‘Garatag’ (1.000). The Unweighted Pair Group Method with Arithmetic Mean (UPGMA) cluster analysis based on Jaccard’s similarity coefficient divided genotypes into four main groups. The first group was the largest and consisted of 12 genotypes, while the fourth group was the smallest consisted of 1 genotype only. The most polymorphic primer was OPB-18 that presented a genetic diversity index of 0.823, while the least informative was primer OPG-17 with an index of 0.349. The average genetic diversity calculated from RAPD data was 0.665.

Grape Cultivars

Two morphologically very distinct grapevines belonging to the subgenera Euvitis and Muscadinia of the genus Vitis are cultivated in the United States. The former is commonly called “bunch” grape, while the latter is usually called “muscadine.” Genetic diversity among these grapes was investigated based on random amplified polymorphic DNAs (RAPDs). Sixteen grape cultivars, with their parentage including V. rotundifolia, V. vinifera, and several American Vitis species, were used for the RAPD analysis. More than 200 RAPDs were produced from 20 random primers. More than 90% of which were polymorphic between the muscadine and the bunch grapes, while polymorphism was considerably low within the muscadine and the bunch grapes. The relationships of grapes between these two subgenera were estimated based on bandsharing and cluster analysis. The result based on the DNA analysis agrees with the isozyme data obtained from a separate study, which demonstrated that the muscadine grape shares very low common alleles with the American bunch grapes and the European grapes.

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.

AbstractSimple sequence repeats (SSR) and random amplification of polymorphic DNA (RAPD) molecular markers were used to assess the genetic diversity of 80 isolates of Phytophthora infestans in potato (Solanum tuberosum) from Fujian, Heilongjiang, Hebei and Inner Mongolia Provinces in China. Polymorphism was identified by 13 SSR primers and 14 RAPD primers in the isolates of P. infestans in potato. A total of 76 bands were amplified by SSRs, with the percentage of polymorphic bands (PPB) being 78.9% and the similarity coefficient ranging between 0.00 and 0.42. A total of 189 bands were amplified by RAPDs, with the percentage of polymorphic bands being 95.2% and the similarity coefficient ranging between 0.04 and 0.66. Analysis of genetic diversity showed that there exists higher genetic variation in the Fujian population in comparison to the populations of Heilongjiang, Hebei and Inner Mongolia. Nei's genetic identity analysis indicates that the genetic similarity between populations of Heilongjiang and Inner Mongolia is the highest and that between Fujian and Hebei is the lowest. A cluster analysis revealed that isolates from Fujian, in the south of China, are distantly related to those from Heilongjiang, Hebei and Inner Mongolia in the north, and the Fujian population is distributed among more groups than the other three, exhibiting a higher genetic diversity.

Castor (Ricinus communis L.), known as castor oil plant or castor bean, is a non-edible oilseed crop. In the present study, the genetic diversity among 54 samples (3 wild and 51 cultivated) collected worldwide was evaluated using inter-simple sequence repeats (ISSRs) and random amplified polymorphic DNA (RAPD) markers. A total of 9 ISSR primers produced 83 high-resolution bands with 61 (74.53%) as polymorphic. The percentage of polymorphic bands per primer and the genetic similarity coefficient ranged from 54.55% (UBC-836) to 100% (UBC-808) and from 0.74 to 0.96, respectively. A total of 11 out of 20 RAPD primers amplified unique polymorphic products with an average percentage of polymorphic bands of 60.98% (56 polymorphic bands out of a total of 90 bands obtained). The percentage of polymorphic bands per primer ranged from 25% (OPA-02 and B7) to 90.91% (B21) with the genetic similarity coefficient ranging from 0.73 to 0.98. The unweighted pair group method with arithmetic averages (UPGMA) dendrogram using two molecular markers divided 54 castor genotypes into three groups. Furthermore, based on morphological data, all 54 castor varieties were grouped into three main clusters. The genetic diversity analysis based on two molecular makers showed that most varieties from China were closely related to each other with three varieties (GUANGDONGwild, ZHEJIANGWild, and HANNANWild) belonging to a wild group separated from most of the cultivated castor samples from China, India, France, and Jordan. These results suggested that the cultivated castor contains a narrow genetic base. Accordingly, we recommend that wild castor genetic resources be introduced for breeding novel castor varieties. Furthermore, the Vietnam, Malaysia, Indonesia, and Nigeria accessions were clustered into the same group. The results of principal coordinate analysis (PCoA) and UPGMA cluster analysis were consistent with each other. The findings of this study are important for future breeding studies of castor.

Abstract Conservation of bamboos for future exploitation as fuel, fibre and as an ingredient for cosmetics depends on knowledge of its natural genetic variation. The study of molecular genetic diversity in bamboos will provide important information for its conservation. This article reports on the genetic diversity in 25 species representing five genera of bamboos found in Indonesia using Random Amplified Polymorphic DNA (RAPD) molecular markers. Out of 40 primers, 24 primers produced 1107 total bands and 86.21% of polymorphic bands across the 25 species. Sixteen bands were uniquely found in one species only and their presence or absence helped to define nine bamboo species. RAPD band sizes ranged from 162 to 2247 base pairs. A dendrogram based on the similarity coefficient of Dice divided the bamboo species into three big clusters. In conclusion, RAPD can capture the diversity among five different bamboo genera and has a great potential to be used in the study of genetic diversity in Indonesian bamboos.

Lelana Ne, Wiyono S, Giyanto, Siregar IZ. 2018. Genetic diversity of Falcataria moluccana and its relationship to the resistance of gall rust disease. Biodiversitas 19: 12-17. The use of cultivars that are resistant to a particular disease is one strategy that could mitigate the incidence of gall rust disease on Falcataria moluccana. Previous studies on the genetic diversity of F. moluccana did not attempt to link that genetic diversity to gall rust disease resistance. This research was carried out using RAPD analysis to determine the preliminary information on the association between different markers and the resistance to gall rust disease. The analysis evaluated a total of 20 pairs of healthy and infected F. moluccana trees that were classified based on their disease severity level. The RAPD primers used in this study were as follows: OPA-05, OPA-08, OPA-10, OPA-13, OPA-18, OPB-07, OPD-13, OPF-02, and OPG-05. The results showed that each RAPD primer produced a varying number of polymorphic bands, ranging from 3 to 12 bands, with a total of 80 polymorphic bands. Despite the number of loci analyzed, however, no specific polymorphic bands were found that could distinguish between healthy and diseased trees. This was supported by principal component analysis, which showed that healthy and diseased populations were not distributed separately. The structure analysis also showed that the healthy and diseased populations were not different.
