Three Iranian native strains and three Japanese commercial lines of the silkworm Bombyx mori were analyzed using amplified fragment length polymorphism (AFLP) markers. A set of ten PstI/TaqI primer combinations amplified a total of 322 bands out of which 251 (%78) were polymorphic. Estimates of Nei’s gene diversity for all loci in individual strains and commercial lines indicated a higher degre...

Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding field crops. Twenty-one microsatellite markers used to assess genetic diversity and relationship of 68 sunflower genotypes (Helianthus annuus L.). All of 21 pairs of SSR (Simple Sequence Repeats) markers produced a total number of 49 polymorphic bands. DNA fragments ranged from 9...

since crosses of lines with suitable genetic distance produce excellent hybrids, the identification of genetic diversity between zea mays l. inbred lines in hybrid maize breeding programs has a high priority. a total of 27 inbred lines plus b73 and mo17 (sc704 parents) were evaluated by 15 inter-simple sequence repeat (issr) primers. inbreds were selected randomly from inbred lines from the agr...

in this research, issr technique was applied to assess genetic diversity among 56 chickpea lines. out of 34 primers, nine primers produced appropriate banding patterns and produced 35 polymorphic bands in chickpea lines. mean percentage of polymorphism of the primers was 66.01 with range of 25 to 100 percent. mean of nei's genetic diversity and shannon information index over all primers we...

Resistance to Fusarium head blight in 32 winter triticale and 34 winter wheat accessions was evaluated. Triticale and wheat were sown in field experiments in two locations. At the time of flowering, heads were inoculated with three Fusarium culmorum isolates. Fusarium head blight index was scored and after the harvest percentage of Fusarium damaged kernels was assessed. Grain was analysed for t...

BACKGROUND Polyploidization is a major evolutionary process in plants where hybridization and chromosome doubling induce enormous genomic stress and can generate genetic and epigenetic modifications. However, proper evaluation of DNA sequence restructuring events and the precise characterization of sequences involved are still sparse. METHODOLOGY/PRINCIPAL FINDINGS Inter Retrotransposons Ampl...
