RAPD (Randomly Amplified Polymorphic DNA) is an indicator for high and stable polymorphism, widely used in the study of the diversity of cassava. In this paper, the results of using 20 polymorphic primers OPK combined with the establishment of the phylogenetic tree to analyze the genetic diversity of 26 cassava varieties with different responses to waterlogging conditions by using the RAPD-PCR technique were presented. The purpose of this experiment was to show the genetic relevance of the studied cassava varieties. The results showed that the flood tolerance of cassava was not related to the polymorphism and branching characteristics of the stem. This information may be use as a basis for selecting flood-tolerant cassava varieties for cassava production, as well as the basis for selecting genetically different parents for breeding.

AbstractGenetic diversity and phylogenetic analyses of 24 species, representing nine sections of the genus Galium (Rubiaceae), have been made using the Inter Simple Sequence Repeats (ISSR), Randomly Amplified Polymorphic DNA (RAPD), and combined ISSR and RAPD markers. Four ISSR primers and three RAPD primers generated 250 polymorphic amplified fragments. The results of this study showed that the level of genetic variation in Galium is relatively high. RAPD markers revealed a higher level of polymorphism (158 bands) than ISSR (92 bands). Clustering of genotypes within groups was not similar when RAPD and ISSR derived dendrograms were compared. Six clades can be recognized within Galium, which mostly corroborate, but also partly contradict, traditional groupings. UPGMA-based dendrogram showed a close relationship between members of section Leiogalium with G. verum and G. humifusum (sect. Galium), and G. angustifolium (sect. Lophogalium). Principal coordinated analysis, however, showed some minor differences with UPGMA-based dendrograms. The more apomorphic groups of Galium form the section Leiogalium clade including the perennial sections Galium, Lophogalium, Jubogalium, Hylaea and Leptogalium as well as the annual section Kolgyda. The remaining taxa of Galium are monophyletic.

AbstractRandom amplification of polymorphic DNA polymerase chain reaction (RAPD-PCR) was carried out to assess the genetic diversity of five new microsporidian isolates viz., NIWB-11bp, NIWB-12n, NIWB-13md, NIWB-14b and NIWB-15mb identified from the silkworms. A type species, NIK-1s_mys was used as control for comparison. Differences in the spore shape, length and width were observed. Of the 30 decamer random primers tested, 22 primers gave repeatable RAPD profiles and yielded a total of 143 fragments, of which 78 were polymorphic (55%). The resulting data was used to derive genetic similarity values for constructing a dendrogram. The neighbour joining method based on Dice coefficients indicate a major cluster comprising NIK-1s_mys, NIWB-11bp and NIWB-12n, whereas NIWB-13md, NIWB-14b and NIWB-15mb appear to be different from each other as well from the major cluster mentioned above which includes the type species (NIK-1s_mys). Based on the reproducibility of RAPD profiles, we are able to identify these microsporidians as different isolates. The RAPD technique may be useful in detecting sources of infection of this economically important domestic insect.
