  Genetic analysis with RAPD markers has been extensively used to determine diversity among maize genotypes. The aim of the present study was to estimate genetic relationships among 70 genotypes, provided from SCDA Turda Cluj germplasm collection. RAPD analysis was performed with 14 decamer primers. These primers generated, among the studied genotypes, a number of polymorphic bands comprised between 13 bands (OPA 04) and 7 bands (OPAL 20). The highest numbers of polymorphic bands were obtained with primer OPA 04, respectively 13 bands, following by OPO 12 (12 polymorphic bands), OPAB 11 and OPA 17 (11 polymorphic bands). Lowest number was obtained with primer OPAL 20, respectively 7 polymorphic bands. Genetic distances were established using Nei-Li coefficient and UPGMA dendrogram was constructed with RAPDistance 1.04 software. The built dendrogram shows phylogenetic relationships between genotypes analyzed.

  Characterization of genetic variability among maize inbred lines can facilitate organization of germplasm and improve efficiency of breeding programs. A set of 83 phenotypically diverse inbred maize lines maintained in Agricultural Research and Development Station (ARDS), Turda, Romania was characterized by pedigree, phenotypically using 14 characters of the plant and ear and genetic with RFLP markers. The objective of this study was to characterize the genetic variability and to define the potential heterotic groups based on clusters formed with marker data. Inbred lines were grouped by their phenotypic differences index in twenty classes. Both the phenotypic and molecular markers analysis indicated high genetic variability and also allowed the separation of the germplasm into group of genetic similarity. The result suggested that the inbred lines analyzed could be useful in maize genetic breeding program.

  Knowledge of genetic diversity and relationships among maize inbred lines is indispensable to a breeding program. Our objective was to investigate the level of genetic diversity among maize inbred lines. Eighty-three maize inbred lines obtained from SCDA Turda were genotyped using 20 decamer primers. These primers generated, among the studied genotypes, a number of polymorphic bands comprised between 17 bands (OPA 03) and 7 bands (OPAB 11). The highest numbers of polymorphic bands were obtained with primer OPA 03, respectively 17 bands, followed by OPA 01, OPB 08 (16 polymorphic bands) and OPX 03 and OPAL 20 (13 polymorphic bands). Genetic distances were established using Nei Li/Dice coefficent and an UPGMA dendrogram was constructed with FreeTree software. The built dendrogram shows phylogenetic relationships between the analysed biological material.
