“…Three provenances originating from Austria, Bosnia and Germany represented the first group, whereas the second and third group consisted of only one provenance (RO63 and RS69, respectively). Formation of groups divergent from those represented by geographic origin showed existence of substantial genetic variability among European beech provenances both from different and similar geographic origins (Pluta et al 2012). Similar results were reported by Pluta et al (2012) for blackcurrant and by Mohamed et al (2011) for palm, even though their results were based on the cultivar level.…”

Abstract:The results of research into leaf stomatal variability of five European beech provenances originating from Austria, Bosnia and Hercegovina, Germany, Romania and Serbia are presented in this paper. Aim of the study was to investigate how stomatal traits of provenances originating from different environments change in response to drought stress and to assess the phenotypic plasticity of the stomatal features investigated. The study was conducted during two different years, characterized by contrasting weather conditions (2010 and 2011). Two-way ANOVA revealed that provenances differ significantly in terms of stomatal density (SD), width of stomatal aperture (W b ), potential conductance index (PCI) and relative stomatal pore surface (RSPS), during both seasons. In a dry year (2011) all provenances significantly increased stomatal density by between 16.1% (Hasbruch -DE) and 21.9% (Cer -SRB). Guard cell length (L A ) was not statistically different among provenances in either year (2010 and 2011), even though L A decreased in the dry year (2011) in all provenances. Reaction norms were steep in most of the parameters suggesting the possibility of a plastic response of provenances toward changes in soil water regime, influenced by the prevailing weather each year. Phenotypic plasticity indices were the highest in regards of SD, PCI and RSPS, indicating that these traits would be good candidates for improvement in breeding programs aimed at selection of drought resistant.

“…Moreover, genetic amelioration of existing crops requires a continuous supply of genetic variation (Rao & Hodgkin ; Pluta et al . ). The two investigated Ribes taxa might be potential crop wild relatives for future Ribes varieties, and the achieved results could be useful to avoid biodiversity loss from climate and other changes, thus defining areas for new breeding programmes.…”

Conservation genetics of two island endemic Ribes spp. (Grossulariaceae) of Sardinia: survival or extinction?

Measuring levels of population genetic diversity is an important step for assessing the conservation status of rare or endangered plant species and implementing appropriate conservation strategies. Populations of Ribes multiflorum subsp. sandalioticum and R. sardoum, two endangered endemic species from Sardinia, representing the whole genus on the island, were investigated using ISSR and SSR markers to determine levels and structure of genetic variability in their natural populations. Results indicated medium to low genetic diversity at the population level: Nei's gene diversity for ISSR markers ranged from 0.0840 to 0.1316; the expected heterozygosity (HE ) for SSR ranged from 0.4281 to 0.7012. In addition, only one remnant population of R. sardoum showed a high level of inbreeding, in accordance with its very small size. Regarding the structure of the six R. sandalioticum populations, both principal coordinates analysis (PCoA) and STRUCTURE analysis of ISSR and SSR data highlighted low population structure, although two populations appeared to be clearly distinct from the others. The genetic pattern of the two taxa associated with their different ecological positions indicated resilience of R. sandalioticum populations in fresh and humid habitats and uncertain future resistance for the residual R. sardoum population in xeric calcareous stands. Hence, this study highlights the importance of an integrated conservation approach (genetic plus in situ and ex situ conservation studies/measures) for activating management programmes in these endemic and threatened taxa that can be considered as crop wild relatives of cultivated Ribes species.

“…The variability of the test cases was analysed in terms of outliers, which were not found in the analysed set. The methodology for this type of analyses, which includes three main stages employing univariate and multivariate methods, has been used in the work of many authors concerning fruit plants, such as strawberry, blackcurrant or heather plants (Lopes et al 2012;Pluta et al 2012;Padula et al 2013).…”

“…The knowledge of the diversity of genotypes among the genetic resources available to the breeder enables appropriate selection of the right parental forms for cross-breeding programs and helps avoid crossing varieties that are genetically related and biologically similar. Valuable assistance is provided here by multivariate statistical methods, which make it possible to estimate the degree of diversity of potential parental forms in terms of many traits (Pluta et al 2012). By conducting a principal component analysis, we can assess the direction and strength of the relationships between the traits being considered.…”

Sieczko L., Masny A., Pruski K., Żurawicz E., Mądry W. The diversity of parental genotypes has a major impact on the progress of plant breeding. This study assessed phenotypic biodiversity of 91 strawberry genotypes in the core collection of the Research Institute of Horticulture in Skierniewice, Poland, using multivariate statistical methods. The assessment was carried out from 2008 through 2010 for 13 traits describing plant growth vigour, flowering and fruit ripening times, fruit yield, fruit appearance and quality (position of the calyx in relation to the surface of the fruit, fruit size and firmness, skin and flesh colour, fruit glossiness, intensity of the fruit's aroma and sweetness), as well as the genotypes' capacity for repeat-fruiting during the summer-autumn period. A principal component analysis using a hierarchical cluster analysis reduced the number of dimensions of more than a dozen traits describing the diversity of the assessed cultivars and identified six homogeneous groups, each consisting of cultivars with similar traits; this will simplify mate selection in the hybridization program and may reduce the size of the core collection.
