Article: Gene pool conservation and tree improvement in Serbia
[show abstract] [hide abstract]
ABSTRACT: This paper presents the concepts applied in the gene pool conservation and tree improvement in Serbia. Gene pool conservation of tree species in Serbia includes a series of activities aiming at the sustainability and protection of genetic and species variability. This implies the investigation of genetic resources and their identification through the research of the genetic structure and the breeding system of individual species. Paper also includes the study of intra- and inter-population variability in experiments - provenance tests, progeny tests, half- and full-sib lines, etc. The increased use of the genetic potential in tree improvement in Serbia should be intensified by the following activities: improvement of production of normal forest seed, application of the concept of new selections directed primarily to the improvement of only one character, because in that case the result would be certain, establishment and management of seed orchards as specialized plantations for long-term production of genetically good-quality forest seeds, and the shortening of the improvement process by introducing new techniques and methods (molecular markers, somaclonal variation, genetic engineering, protoplast fusion, micropropagation, etc.).Genetika. 01/2009; -
Article: Genetic characterization of genotypes of Austrian pine (Pinus nigra Arnold) populations using protein markers
[show abstract] [hide abstract]
ABSTRACT: The occurrence of Austrian pine over large areas attacked by erosion processes or on completely degraded and denuded areas on which it produces excellent results, classifies it among the most important economic species in forestry. The aim of present research is to study intra- and inter-population genetic variation in Austrian pine by the application of biochemical markers. A better knowledge of the genetic potential of Austrian pine populations will enhance the production of seed and planting material, and in this way also the success of a forestation and the establishment of Austrian pine specific-purpose plantations. The polymorphism of protein markers was determined based on the selected genotypes originating from six populations (seed stands), which actually included all Austrian pine populations in Serbia. Based on the derived electrophoregram, qualitative and quantitative differences (number and pattern) in protein fractions were identified and the seed protein profile was constructed for each tree, as well as for each of the six study populations. This showed the 'conservativeness' of some polypeptides, i.e. the presence in all analyzed genotypes. On the other hand, some protein fractions were variable at the population level, and some were variable depending on the population. Based on the electrophoregram, the coefficient of genetic similarity/distance was calculated by comparing the band numbers and patterns. Cluster analysis dendrograms were also constructed. The degree of genetic variation among the provenances was higher than the variation within the provenances. There was also a high genetic variation in seed proteins within the analyzed populations.Genetika. 01/2008; -
Article: The use of molecular markers in the improvement of conifer tree species
[show abstract] [hide abstract]
ABSTRACT: The paper reviews the study results of the use of molecular markers in coniferous tree species improvement. The results are based on presentation of the experience in the application of biochemical and molecular analyses at the level of the selected populations and individuals from different provenances of coniferous tree species. Many studies performed during the last years demonstrated the usefulness of neutral molecular markers in the field of conservation and population genetics of conifers, in particular to understand the importance of migration patterns in shaping current genetic and geographic diversity and to measure important parameters such as effective population size, past bottlenecks and gene flow. This is relevant to design conservation strategies but is of little value to understand the adaptability patterns. In the specific field of the conservation genetics, molecular markers can be extremely useful in both ex situ and in situ gene pool conservation of coniferous trees.Glasnik Šumarskog Fakulteta. 01/2008;
