THE CYTOPLASM ORIGIN INFLUENCE, THE TESER INFLUENCE AND THE NUCLEUS-CYTOPLASM INTERACTIONS INFLUENCE ON EAR AND KERNEL TRAITS FOR ISONUCLEAR LINES PUBLISHEDCamelia Gabriela Racz, I. Haş, Voichiţa Haş, I. Coste, Teodora Şchiop None
Most of the traits that contribute to the achievement of maize yield / plant (the ear size, the ear length, kernel rows/ ear, kernel number/ row, thousand kernel weight) are genetically induced mostly at nucleus level. There have been studied the following maize ear traits for five isonucleus inbred lines: ear weight (g), kernel weight per ear (g), kernel rows per ear, kernel number per row, ear diameter(cm), rachides diameter(cm), thousand kernel weight (g), kernel depth and the kernel yield per ear. The research has been conducted in the experimental field provided by the Maize Breeding laboratory from Agricultural Research and Development Station Turda. The value of inbred lines is reflected in single-crosses, triliniar-crosses or double-crosses of which forms part as parental inbred lines. For inbred isonuclear lines their genetic value will be enhanced by their use in single-cross combinations as maternal forms.
