ESTIMATION OF COMBINING ABILITIES AND GENE EFFECTS FOR PLANT HEIGHT AND HEAD DIAMETER IN SUNFLOWER
Procjena općih (OKS) i specifičnih (SKS) kombinacijskih sposobnosti linija, učinaka gena te izdvajanje najboljih hibridnih kombinacija za visinu biljke i promjer glave sastavni je dio oplemenjivačkog programa na suncokretu, a provodi se zbog izbora linija koje će omogućiti stvaranje hibrida dobrih agronomskih svojstava. Istraživanjem je obuhvaćeno 6 inbred linija, 15 dvolinijskih križanaca, 15 eksperimentalnih trolinijskih križanaca i tri priznata hibrida. U procjeni kombinacijskih sposobnosti korišteni su samo F1 izravni križanci. Značajnost razlika između srednjih vrijednosti hibrida je testirana LSD testom, u prvoj godini u odnosu na prosjek pokusa, a u drugoj u odnosu na komercijalni hibrid Orion, koji je standard za priznavanje hibrida suncokreta. Na oba lokaliteta, najviše učinke OKS za visinu biljke ostvarila je linija L- 5, a za promjer glave linija L- 103. Najniže učinke SKS za visinu biljke ostvarili su križanci 5A x 103B i 101A x 302B. Najbolje kombinacije za promjer glave su 5A x 302B i 103A x 219B. Udio genetske u odnosu na okolinsku varijancu bio je veći za visinu biljke, a manji za promjer glave. Istraživanje je pokazalo da su za visinu biljke aditivni genetski učinci važniji od dominantnih, a za promjer glave važniji su dominantni učinci.Estimation of general (GCA) and specific (SCA) combining abilities of lines, gene effects as well as extraction of the best hybrid combinations for plant height and head diameter is integral part of sunflower breeding program at the Agricultural Institute Osijek. It conducts it due to choice of lines that will enable creation of hybrids with good agronomic traits. The research included 6 inbred lines, 15 single crosses, 15 experimental three way and three approved hybrids. Only F1 direct crosses were used in the estimation of combining abilities. Significance of differences among mean values of hybrids was tested by LSD test, in the first year in relation to mean of trial, and in the second year in relation to commercial hybrid Orion being a standard hybrid for approval of new sunflower hybrids. On both localities, the highest GCA effects for plant height were realized by the line L-5, and for head diameter line L-103. The lowest SCA effects for plant height had crosses 5A x 103B and 101A x 302B. The best combinations for head diameter are 5A x 302B and 103A x 219B. Portion of genetic in relation to environmental variance was higher for plant height, and lower for head diameter. The research has shown that additive gene effects for plant height were more important than dominant effects, but for head diameter dominant effects were more important

Basic morphological characteristics of the Rana (Pelophylax)
synklepton esculenta complex in relation to legal regulations in Serbi
Population composition and genetic variation of water frogs (Anura : Ranidae) from Yugoslavia
Species of the Rana kl. esculenta complex from twenty-one localities of the North-Western part of the Balkan Peninsula (Yugoslavia and Macedonia) were analyzed by electophoretic, morphometric and cytogenetic methods. The results of this research revealed that species that belong to the R. hi. esculenta complex from localities in Northern Yugoslavia form a ridibunda/esculenta/lessonae (R-E-L) population system of diploid forms of two parental species and predominantly female hybrids. Pure R ridibunda populations exist south of the Sava and Danube Rivers. The unequal sex ratio observed in water frog population systems suggests, according to Haldane's rule, that the heterogametic sex suffers the effects of hybridization. Electrophoretic analysis shows that some introgression of ridibunda alleles into R. lessonae, as well as lessonae into R. ridibunda has taken place. The occurrence of recombinations, and cytogenetic characteristics of the chromosome complements, does not support pure hybridogenesis as a general mode of reproduction in the hybrid form R. kl. esculenta from the examined localities.nul
