dc.description.abstract | In order to enable progress in sunflower breeding, an increasing amount of attention has to be paid to the morpho-physiological traits (petiole angle and length) of this crop that have a significant effect on its seed yield and oil concentration. In the inheritance of petiole angle and petiole length the additive component of genetic variance had the predominant role in the F1 and F2 generation. The mean degree of dominance (H1/D)1/2 and the intersection of the expected regression line with the Wr axis indicated partial dominance in the inheritance of petiole angle and petiole length. Broad sense heritability for petiole angle was 88% and for petiole length 85%. | en |
dc.description.abstract | Da bi se obezbedio napredak u selekciji suncokreta potrebno je obratiti veću pažnju na morfo-fiziološke osobine (ugao lisne drške i dužinu lisne drške) koje značajno utiču na prinos semena i sadržaj ulja. Radi proučavanja nasleđivanja, efekta gena, komponenti genetske varijanse i heritabilnosti ugla i dužine lisne drške šest genetski divergentnih inbred linija suncokreta u F1 i F2 generaciji primenjena analiza dialelenih ukrštanja za kombinacione sposobnosti, Griffing, 1956 metod 2, model I. Za ocenu komponenti genetske varijanse i regresionu analizu korišćen je metod MATHER and Jinks (1982). Ocena heritabilnosti u užem smislu je rađena po formuli MATHER and Jinks (1971). U nasleđivanju ugla i dužine lisne drške aditivna komponenta genetske varijanse je bila predominantna u F1 i F2 generaciji. Prosečan stepen dominacije (H1/D)1/2 i presek očekivane linije regresije sa Wr osom ukazuje na parcijalnu dominaciju u nasleđivanju ugla i dužine lisne drške. Heritabilnost u užem smislu za ugao lisne drške iznosi 88%, a za dužinu lisne drške 85%. | sr |
