Opis:
The usefulness of mutagenic treatment to enlarge isozymic variability of barley and the use of induced mutants for genetic analysis were evaluated. N-methyl-N-nitroso urea, sodium azide and gamma rays were employed as mutagenic agents. Electrophoretic assays of 3848 M₂ seedlings obtained by chemical mutagenic treatment of the spring barley cultivars Dema, Aramir, Bielik and 3100 M₂ seedlings obtained by physical mutagenic treatment of the cv. Dema revealed 70 isozymic mutants, which represent 30 separate mutants in 25 M₁ plants. Most of mutations (27) were induced by chemical mutagen at polymorphic esterase loci. The occurrence of induced mutants at monomorphic loci, Got2 and Lap2, made it possible to perform genetic analysis of those loci in barley including mapping respective genes within chromosomes.

Opis:
Evolutionary processes lead to the survival of individuals best adapted to local environment. This gives rise to allele polymorphism and genetic diversity of populations. Isoenzyme proteins, which are the product of gene expression, are an effective tool for tracking these changes. On the other hand, the reproductive potential of a given population can be assessed based on its ability to produce viable and efficiently germinating seeds. The present results combine molecular analyses of isoenzyme proteins with anatomical and morphological studies of Scots pine seeds (Pinus sylvestris L.). The study was conducted in 6 populations that are characteristic of this species occurrence range in the country. The results confirm the correlation between seed weight and embryo size. They also show a population from northeastern Poland had a higher effective number of alleles and seed with lower germinative energy and capacity. There was genetic homogeneity in all except for the population from Woziwoda, which was significantly different based on the Fst test. The genetic characteristics of Scots pine from Woziwoda may be associated with the lower levels of rainfall that occur there during the growing season. The results improve our knowledge of Scots pine variability and contribute to the discussion of the impact of local environment on genetic variability.

Opis:
The genetic structure of Norway spruce [Picea abies (L.) Karst] of the Istebna race was studied in two populations from the Carpathian seed stands in the Malinka and Czarne Forestries. The recent provenance test results have shown a high quality of both populations. The results were compared with the genetic variation parameters calculated for the selected seed stand from the Bukowiec Forestry (compartment 149h), whose genetic structure in the progeny test for this species is considered a national standard. Five enzyme systems were analysed. The results show that the mean number of alleles per locus and the heterozygosity observed in the analysed populations are greater than those reported in the literature for other natural Norway spruce populations from the Carpathians. The heterozygosity level of the studied seed stands was higher than of the selective population of the Istebna spruce plus trees and the level of genetic diversity was similar to that of the Bukowiec seed stands. Thus, it can be concluded that the analysed seed stands from Czarne and Malinka, compartment 91h can be used as a supplementary seed base. However, at the individual partial population level, the Bukowiec spruce population, compartment 149h is considered to be of the highest value.

Opis:
The genetic variation of Norway spruce provenances from fourteen geographical regions were tested in the IPTNS−IUFRO 1964/68 experiment in Krynica. The genetic structure of seven isozyme systems coded by eleven loci was described. Parameters of genetic polymorphism i.e. the average number of alleles per locus and observed heterozygosity were 1.47 and 0.12, respectively. The spruces from Belarus were characterised by the highest genetic diversity, while the provenances from south−eastern Styria – the lowest. The values of Wright's inbreeding coefficient varied from –0.417 for the Romanian provenances to 0.223 for the provenances from 28 th Krutzsch regions (Tyrol−Salzburg; Austria).
