Analyses of individuals classically treated as Juniperus oxycedrus L. var. oxycedrus from Morocco, Portugal, Spain, France, Italy, Greece and Turkey, using DNA sequencing of nrDNA (ITS 1, 5.8S, ITS 2) plus RAPDs, leaf terpenoids and morphology revealed that two cryptic, genetically distinct but morphologically almost identical species are present. These species, J. oxycedrus L. var. oxycedrus a...

A linkage map of rye, previously developed using DS2 x RXL10 F2 mapping population, was enriched with 179 AFLP and 19 RAPD marker loci. The current map covers 1386 cM and contains 480 markers including 200 RFLPs, 179 AFLPs, 88 RAPDs, 12 protein loci and one dwarfing gene. AFLPs generated by EcoRI/MseI primer combinations were distributed over the entire genome as distinct loci or clusters of 2-...

The more than 100 almond cultivars grown in Apulia (South Italy) could be a source of genetic variation adapted to the Mediterranean environment, provided that a proper classification, identifying similar characteristics and synonymous cultivars, is made. DNA-based assays could integrate traditional classifications based on morphology. In the comparison of 17 Apulian almond cultivars, by random...

The Pleistocene and recent distributions of the taxa are discussed. A new variety of Juniperus ashei, J. ashei Buch. var. ovata R. P. Adams is recognized from west Texas and northern Mexico. It differs from typical J. ashei in having whip leaf glands that are oval to elongate rather than hemispherical, smaller female cones, smaller seeds and more seeds per cone. In addition, the leaf oil of var...

Genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (Musa acuminata cv. Dwarf Cavendish (AAA)) were studied using morphological and random amplified polymorphic DNA (RAPD) markers. Out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...
