Opis:: The comparison of phenotypic trait differentiation and genetic differentiation at selectively neutral genetic markers can indicate divergent selection on traits. Phenotypic trait differentiation (PST) andtwo multivariate analysis methods were used to determine the level of differentiation and relationships among seven Juniperus excelsa populations basedon 13 morphological characters of their cones, seeds, juvenile seedlings and 1+0 year old seedlings. Significant differences among populations were found for all morphological characters (P<0.001) apart from cotyledon length using ANOVA. According to Penrose and Squared Euclidean distances, the southeastern populations Bucak-Kestel and Gölhisar-Gölhisar (0.970; 12.374) were most similar. Aksu-Sorgun andE ðirdir-Barla populations, separated by a mountain range, were the most different populations (4.647; 47.157). Evaluatedas a whole, both multivariate analysis methods gave similar results. Phenotypic trait differentiation (PST) for 1+0 year oldseed lings that were grown in a common environment was similar in magnitude for the majority of traits as genetic differentiation at nuclear microsatellite markers (FST) suggesting the absence of divergent selection on these traits.

Opis:: Variation of traits is a primary need of any plant breeding effort that involves the natural evolution and causes sustainable crop production under different environments. Fifty six bread wheat genotypes grown during the growing season of 2012/2013 were evaluated for variability characteristics for eighteen traits i.e., stem diameter, plant height, leaf number, leaf length, leaf width, tiller number, internode length, peduncle length, spike length, floret number, spikelet number, grain number, awn length, grain diameter, grain length, number of days to flowering, thousand seed weight and grain yield. Significant differences were observed for all the traits studied, indicating a considerable amount of variation among wheat genotypes for each trait. The estimates of the coefficient of variation (CV) were high for grain yield and number of tillers per plant. Spike length varied from 8.95 in G28 to 4.74 in G40, while genotype G20 had the maximum floret number (19). According to thousand seed weight, genotype G55 had the maximum thousand seed weight (45.57 g) and genotype G4 had the maximum grain yield performance (6936.3 kg ha-1). The information on diversity among the agro-morphological traits of the studied wheat genotypes will be helpful to plant breeders in constructing their breeding materials and implementing selection strategies.

Opis:: In order to evaluate the relationship between traits affecting the seed yield of the garden cress, phenotypic correlations between seed yield and yield components were detected, direct and indirect effects of yield components on yield and its role in the description of diversity were estimated, and the experiment was conducted in a randomized complete block design with three replications in 2017. The ANOVA showed that the difference among accessions was significant for all traits. There was a significant phenotypic correlation between yield and most of the traits. The highest value of phenotypic correlation was obtained between seed yield and the ‘thousand seed weight’ (0.97). The regression analysis showed that the seed yield was highly influenced by the ‘thousand seed weight’, leaf height and the number of seeds per silique of the lateral branches and the main axis. These three traits constituted about 89% of changes in the total yield, while the ‘thousand seed weight’ was the most effective trait that entered the model and explained 51% of the variation. The path analysis of phenotypic correlation showed that the ‘thousand seed weight’ had the greatest direct effect on the yield (7.21). The ‘thousand seed weight’ had a positive indirect impact on other traits as well. As a result of the factor analysis, 3 independent factors explained about 79.33% of the yield variation. These factors consisted of the number of seeds per silique of the lateral branches, the number of seeds per silique of the main axis and the ‘thousand seed weight’.

Opis:: Sweet chestnut forests in Bosnia and Herzegovina are underrepresented in the total forest fund, and their area is declining today. The research aims to determine the correlation relations of morphological traits of chestnut leaves, fruit and cupule in the population of Bosnian Krajina (northwestern Bosnia and Herzegovina) to undertake selection and breeding activities. Eleven traits of fruits, leaves and cupules were measured, seven assessed and six calculated. A mutual correlation for the researched traits was calculated using the Pearson correlation coefficient r. When the fruit traits and cupule traits were compared, the needle length showed a statistically significant correlation with most of the fruit traits. The traits of the number of fruits in the cupule and needle length had a statistically significant correlation coefficient with leaf blade width and leaf petiole length. The correlated traits can be distinguished as important for further selection and breeding of sweet chestnuts. The research results indicate that the genetic material of sweet chestnut is a rich source of genetic diversity and can be used in selection to obtain new varieties and cultivars in Bosnia and Herzegovina and for the protection of the indigenous gene pool.

Opis:: Kolekcja zasobów genowych z rodzaju Lycopersicon obejmuje 947 obiektów. W kolekcji roboczej jest prowadzona ocena cech ilościowych i jakościowych obiektów pomidora z banku genów. Każdego roku wybrana liczba obiektów jest waloryzowana pod względem 42 cech morfologicznych i użytkowych, zgodnie z klasyfikatorem cech IPGRI. Badane cechy obejmują 10 cech dotyczących rośliny i 32 cechy owoców. Zaprezentowano wyniki dotyczące 25 wybranych obiektów pomidora pochodzących z: Bułgarii, Czech, Wielkiej Brytanii, Francji, Rosji, USA i Polski. Oceniano między innymi takie cechy owoców jak: wielkość, kształt, twardość, barwę owoców, intensywność zielonej piętki, żebrowanie, łatwość usuwania szypułki, przekrój owocu, grubość perykarpu, liczbę komór nasiennych, obecność pustych przestrzeni, jak również typ wzrostu i wrażliwość na choroby. Badane obiekty charakteryzowały się dużą zmiennością badanych cech. Poszczególne obiekty mogą być wykorzystane jako wartościowy materiał w hodowli nowych odmian do świeżej konsumpcji, jak i do przetwórstwa. Zasoby genowe pomidora pochodzące z różnych regionów, dostarczające unikalnych cech (cherry type, owoce o żółtym lub malinowym zabarwieniu, o sercowatym kształcie, rośliny karłowe zwarte, itp.), mogą poszerzać asortyment odmian dla amatorskiej produkcji. Zadaniem kolekcji jest zabezpieczenie przed zaginięciem zasobów genowych, jak również ma ona służyć jako źródło zmienności genetycznej. W oparciu o przeprowadzone obserwacje wybrano szereg obiektów do prac hodowlanych i innych badań (np. jako źródło wczesności, twardych owoców, owoce o grubym perykarpie, o intensywnej barwie zewnętrznej i wewnętrznej, tolerancji na Phytophtora infestans, itp.).
The Gene Bank collection of genotypes of Lycopersicon ssp. consists of 947 accessions. The working collection is maintained to estimate the quality and quantity characters of tomato genetic resources. Each year a selected number of tomato accessions from gene bank is characterised in regard to 42 morphological and economic traits according to IPGRI descriptor list. These traits include 10 traits of plants and 32 traits of fruits. The results of investigations obtained on 25 tomato accessions originating from Bulgaria, the Czech Republic, Great Britain, France, Russia, USA and Poland are presented. The following important characters of fruits the: size, shape, firmness, colour of fruit, intensity of greenback, ribbing, easiness of fruit to detach from the pedicel, fruit cross-sectional shape, thickness of pericarp, number of locules and also the growth type and susceptibility to diseases were described. The examined accessions are characterized by a great variation of qualitative and quantitative traits of tomato genetic resources. Numerous accessions can be used as a valuable material in the breeding of new cultivars for fresh market and processing. Genetic resources of tomato from various origins provide genotypes with unique, favourable, useful traits, which can enlarge the assortment of tomato cultivars (cherry type, yellow, heart shape fruits, dwarf compact plants etc.) for amateur production. The tomato collection is designated to preserve the germplasm against the disappearance, as well as, a rich source of genetic variability. On the basis of observations some of genotypes were chosen for breeding work and other research (i.e. source of earliness, of fruit firmness, thick pericarp, colour intensity, fleshy homogeneity, tolerance to Phytophtora infestans, etc.).

Opis:: The aim of the work was characterization of morphological diversity and DNA polymorphism of common oat landraces. 25 Morphological traits and DNA polymorphism have been examined using AFLP methods. It has been found, that identification of oat landraces is possible based on the examined morphological traits. The examined accessions were differentiated by traits important for intraspecific taxonomy of oat: type of panicle, presence of awns, colour of grain, as well as other morphological traits, such as shape of panicle, rigidity of stem leaves, and type of awns. Relationships of morphological traits of leaves, grains, and stem with some DNA fragments suggesting presence of molecular markers of these morphological traits have been found. Morphological similarity of landraces doesn’t correspond to affinity complied with DNA similarity of these objects...

Opis:: The aim of the study was to determine the biomass and nitrogen accumulation in early maturing soybean plants experiencing contrasting weather conditions. Soybean (Glycine max) is a species of agricultural crop plant that is widely described in scientific publications. During 2014–2016, a field experiment with early maturing soybean ‘Merlin’ was carried out at Grodziec Śląski, Poland (49°48'01" N, 18°52'04" E). Results showed that the morphological traits of the plants, the yield of individual plants, and the soybean crop were all closely related to the climatic conditions. A high amount of precipitation stimulated seed development, resulting in a high production potential. The harvest index calculated for soybean ‘Merlin’ was high and exceeded 0.5 g g−1. The nitrogen content of the aboveground biomass increased during ontogenesis. The maximum yield of dry matter was noted at the green maturity phase, which subsequently decreased at the full maturity phase because of the loss of the leaf fraction. The variation in the effectiveness of nitrogen accumulation in seeds between 2015 and 2016 was 30%. The nitrogen harvest index values were high in each year of the experiment and exceeded 0.92 g−1. For the production of 1 ton of seeds with an adequate amount of soybean straw, plants needed, on average, 68 kg of nitrogen.
Celem badań było określenie akumulacji biomasy i azotu we wcześnie dojrzewającej odmianie soi [Glycine max (L.) Merr.] w zmiennych warunkach pogodowych. W latach 2014–2016 w Grodźcu Śląskim (49°48'01" N, 18°52'04" E) przeprowadzono eksperyment polowy z wcześnie dojrzewającą odmianą soi ‘Merlin’. Wykazano, że cechy morfologiczne roślin soi oraz plonowanie były ściśle związane z warunkami klimatycznymi. Wysoka ilość opadów stymulowała rozwój nasion, dając w rezultacie wysoki potencjał produkcyjny. Indeks żniwny (HI) obliczony dla odmiany ‘Merlin’ był wysoki i przekraczał 0.5 g g−1. Zawartość azotu w nadziemnej biomasie wzrastała wraz z rozwojem generatywnym roślin. Maksymalną wydajność suchej masy odnotowano w początkowej fazie dojrzewania. W fazie pełnej dojrzałości wydajność suchej masy spadła, z powodu utraty frakcji liści. Zróżnicowanie w efektywności akumulacji azotu w nasionach w latach 2015–2016 wyniosło 30%. Wartości indeksu żniwnego azotu (NHI) były wysokie w każdym roku doświadczenia i przekraczały 0.92 g g−1. Do produkcji 1 tony nasion z odpowiednią ilością słomy rośliny potrzebowały średnio 68 kg azotu.

Opis:: In this study, gene action, genetic variances (δ2A and δ2D ), and combining abilities were estimated for fruit related traits using North Carolina Design ІІ (NCD ІІ) for ten different parental genotypes of greenhouse cucumber. This experiment was performed over a two-year period from 2014 to 2015. The variance components of male, female, and male × female were found to be significant for all the studied traits in a combined analysis of variance. Genetic component analysis showed that fruit diameter, fruit length, total fruit weight, fruit number in early picking and fruit number per node were predominantly under the additive gene action, but internode length and plant height were under the dominance of gene action. Male × female × environment interaction was significant for total fruit weight. The highest general combining ability (GCA) effect for total fruit yield was observed in Zohal (male parent) and YaldaR2 (female parent) genotypes. GCA estimation revealed that male parent of Adrian 4510 provided good general combiners for total fruit number. Specific combining ability (SCA) estimation determined the suitability of Janeete × Adrian 4510. Salar hybrid exhibited higher positive SCA effects for total fruit yield and total fruit number in early picking.

Opis:: To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.
