The development of new hybrids with a high genetic potential for seed and oil yields based on interspecifi c hybridization requires information on the mode of inheritance and combining abilities
of the newly developed inbred lines for total seed number per head (TSN) and 100 seed mass (100SM). Th e interdependence between yield components and seed yield (SY) in order to select promising lines to be used subsequently as components of future sunflower hybrids. In the present study, we used seven new divergent (A) cytoplasmically sterile inbred lines obtained by interspecific hybridization, three Rf-restorer lines used as testers, and 21 F1 hybrids developed at the Institute of Field and Vegetable Crops in Novi Sad. The female inbred lines had been developed by interspecific hybridization, while the three male restorer inbreds with good combining abilities were used as testers in the form of fertility restorers. A trial was set up at the Rimski Šančevi Experiment Field of the Institute o...f Field and Vegetable Crops in Novi Sad using a randomized block design with three replications. The mean values and coefficient of correlation (r) as indicators of interdependence between two variables were determined according to Hadživuković (1991). Analysis of combining abilities was done by the line x tester method (Singh and Choudhary, 1976). Significant differences in TSN and 100 SM were found between the A-lines and the Rf-testers and their F1 hybrids. Analysis of combining abilities showed that there were signifi cant differences between the A-lines and Rf-testers in the GCA for both traits under study. Highly significant positive GCA values were found in the A-lines NS-GS-4 and NS-GS-5, while the NS-GS-6 inbred had a highly signifi cant negative value of the GCA for both traits. Among the Rf-testers, highly significant positive GCA values were found in RHA-N-49 for TSN and RHA-RPL-2/1 for 100 SM. Th e highest and highly significant positive SCA value for both traits was recorded
in the hybrid NS-GS-5 x RHA-R-PL-2/1. Th e nonadditive component of genetic variance had the main role in the inheritance of TSN and 100 SM, further supporting this was the GCA to SCA ratio in the F1 generation of less than one (0.11, 0.24). The largest average contribution in the expression of TSN was found in the Rf-testers (55.8%), whereas with 100 SM, the contribution of the A-lines was more significant (70.6%). Signifi cant positive interdependence was established between SY and TSN (0.376*). Between SY and 100 SM, there was highly significant positive interdependence (0.823**).
