Perennial ryegrass (Lolium perenne L.) is the most important grass species used in temperate grassland agriculture. Our objective was to obtain an overview of the genetic relationships between 20 individual genotypes of perennial ryegrass of diverse origins, using amplified fragment length polymorphism (AFLP), inter-simple sequence repeat (ISSR), random amplified polymorphic DNA (RAPD) and two sets of simple sequence repeat (SSR) markers. All 20 individuals were uniquely fingerprinted by all four marker systems and comparisons were made on the basis of 85 markers each. Mean genetic similarities were estimated at 0.31, 0.43, 0.23 and 0.15 for AFLPs, ISSRs, RAPDs and SSRs, respectively. Cophenetic values resulted in good (AFLP and SSR-B = 0.88) to moderately good fits (ISSR = 0.76, RAPD = 0.70, and SSR-A = 0.79). Comparing the four marker systems to each other, AFLP and SSR-A were correlated best (r = 0.57). All other comparisons revealed rather low correlation coefficients in the Mantel Z test. With twice as many markers cophenetic values increased to a very good fit for AFLPs (0.90) and SSRs (0.92).

The genetic diversity of 27 mulberry (Morus spp.) genotypes mainly from China was investigated using inter-simple sequence repeat (ISSR) markers to assist in addressing breeding objectives and conserving existing genetic resources. Of the 22 primers screened, 15 produced highly reproducible ISSR bands. Using these 15 primers, 138 discernible DNA fragments were generated with 126 (91.3%) being polymorphic, indicating considerable genetic variation among the mulberry genotypes studied. Genetic similarity ranged from 0.6014 between Yu 2 and Yu 711 to 0.9493 between Cuizhisang and Dejiang 10. The phenetic dendrogram based on ISSR data generated by the unweighed pair group method with arithmetical averages (UPGMA) method grouped the 27 accessions into two major clusters: cluster I, cultivated mulberry species (M. multicaulis Perr., M. alba Linn., M. atropurpurea oxb., M. bombycis Kiodz., M. australis Poir., M. rotundiloba Kiodz., M. alba var. pendula Dipp., M. alba var. macrophylla Loud., and M. alba var. venose Delile.); and cluster II, wild mulberry species (M. cathayana Hemsl., M. laevigata Wall., M. wittiorum Hand-Mazz., M. nigra Linn., and M. mongolica Schneid.). Our molecular analyses agree with the existing morphological classification of Morus and clarify the genetic relationships among mulberry species.

Genetic diversity was assessed in 50 accessions of seven <italic>Lens</italic> species using ISSR markers. The collection included accessions of the cultivated species <italic>L. culinaris</italic> and six wild species, <italic>viz</italic>., <italic>L. culinaris</italic> ssp. <italic>odemensis, L. culinaris</italic> ssp. <italic>orientalis</italic>, <italic>L.</italic> <italic>orientalis, L. nigricans, L. lamottei</italic> and <italic>L. ervoides.</italic> The 23 ISSR primers amplified a total of 368 bands with an average of 16 bands per primer. Maximum number of 20 bands was amplified using each of the primers ISSR-34 and ISSR-835. All the primers were found to be polymorphic. PIC values ranged from 0.02 to 0.80. The primers ISSR-807, ISSR- 809, ISSR- 827, ISSR- 847, ISSR-28 and ISSR- 37 were found to be very useful for analyzing the molecular diversity of the genus <italic>Lens</italic>. Cluster Analysis and Principal Coordinates Analyses placed the 50 accessions into two groups and complemented each other.
