A total of 9\nenzyme systems were studied, accounting for 14 putative loci, 8 of which were polymorphic. The analysis of\ngenetic diversity revealed a low level of within accession variation (HS=0.013), while between accession diversity\n(DST ) was 0.120. Coefficient of gene differentiation (GST ) was 0.905, indicating that most variation was among\naccessions. Nei's genetic distances were calculated on the basis of allelic frequencies and a UPGMA dendrogram\nwas constructed.\nTwenty arbitrary 10mer\noligonucleotideswere used in RAPD analysis. Amplification profiles disclosed a higher\nlevel of polymorphism than isozymes.Based on amplification patterns, the similarity index of Jaccardwas calculated\nand a dendrogram constructed on the basis of the similarity matrix. The final clustering based on RAPD data was\nsimilar to the one obtained using isozyme allelic frequencies.\nThe classification in botanical varieties did not reflect the allelic constitution of the different samples. On the\nother hand, referring to geographical origin, most accessions from Africa and from Latin America were distributed\nrespectively in two distinct clusters in the dendrogram. This grouping might also reflect the differences observed in\nthe germination behaviour of V. vexillata from the two continents." ; prodottidellaricerca:prodottoDi istituto:CDS041 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA16742 , unitaDiPersonaleInterno:MATRICOLA612 . ns10:ID250796 pubblicazioni:rivistaDi prodotto:ID228539 .
