Intra-cultivar Diversity in sicilian and calabrian olive (olea europaea L.) Cultivars Depicted by Morphological Traits and SSR Markers

In this study, SSR analysis was performed on a large number of putative clones of the main olive cultivars from two Italian regions, Sicily and Calabria, in order to study the genetic relatedness, and to detect any degree of genetic diversity, which can be used to unambiguously identify possible superior clones. These putative clones have been collected and observed in the last ten years, following an extensive investigation carried out in traditional olive growing areas, thanks to the reports of farmers, millers, technician, growers and nurseries. The set of microsatellite (SSR) markers used allowed the detection of the genetic diversity, resulting from somatic mutation, indicating the pre…

Identification of self(in)compatibility genotypes and microsatellite marker based fingerprinting of traditional italian sweet cherry accessions

Italy is one of the main European sweet cherry producers and it has a rich germplasm, including many minor local varieties that have not been well studied or used in breeding programmes. Sweet cherry is self-incompatible, with few exceptions; its incompatibility is controlled by a multi-allelic S locus, which is gametophytically expressed. The knowledge of S-alleles and cross-incompatibility groups of sweet cherry genotypes and cultivars is important for growers and breeders. In this work we analysed 48 traditional sweet cherry varieties and cultivars, mainly from Calabria and Emilia Romagna regions, together with eight Sicilian cultivars and the standard set of reference genotypes proposed…
