The results are discussed with regard to the distribution of the genetic diversity level and the genetic resources management.Īrus P. rupestris populations genetic distance values resulted rather low and they resulted high with B. The among-population component of the total genetic diversity (Gst mean values) for each species was 0.30–0.37, indicating genetic differentiation among populations.Īmong B. In some cases a great number of heterozygous individuals were detected, in other cases fixation index (F) deviated significantly from Hardy-Weinberg genotypic expectations.Ī total of 37 alleles was recognized, six of which resulted exclusive to single populations. Mean within-population genetic diversity was moderate (P = 41%, A = 1.54, H = 0.16). These taxa represent a genetic resource as relatives of kale crops but some populations are endangered or threatened, thus isozyme analyses were performed to assess the genetic diversity degree at population and species levels in order to assist the design of conservation management programs.Įleven loci from five enzyme systems (aconitase, leucine aminopeptidase, 6-phosphogluconate dehydrogenase, phosphoglucoisomerase phosphoglucomutase) were analyzed in sixteen natural population (fifteen from Sicily, one from Calabria). In Sicily and in the small surrounding islands the section Brassica of the genus Brassica comprises five species, B.
