Sažetak
The level of genetic divergence between two maize inbred lines is sometimes correlated with heterosis level of their F1 offspring. SSR marker polymorphisms can be used to assess the level of genetic divergence or similarity among elite inbred lines. The objectives of the study were to 1) determine polymorphic SSR loci among elite maize inbred lines, and 2) estimate genetic similarity among elite maize inbred lines and compare the obtained results with the pedigree of inbred lines. For analysis of polymorphism, we used 15 maize inbred lines and Illinois High Oil (IHO) high oil source. Polymorphisms were detected with 73 public SSR markers on agarose gels ; 39 useful polymorphic marker loci were found. The Dice genetic similarity (GS) index was calculated for 11 maize inbred lines and IHO high oil source. On the basis of values for GS index the most divergent pairs of inbred lines were Bc7 and Bc12 (40, 0), Bc9 and Bc10 (42, 4) and Bc6 and Bc12 (42, 7) while the most similar pairs of inbred lines were Bc7 and Bc9 (80, 0), Bc1 and Bc5 (80, 0), and Bc2 and Bc9 (82, 9). The high oil source IHO was found to be the most divergent from inbred lines Bc6 (45, 5) and Bc8 (44, 7), while it was the most similar to inbred line Bc1 (68, 3). Cluster analysis, based on SSR data, clustered maize inbred lines, in most cases, according to expectations based on pedigree data and indicated that such data can be used for prediction of heterosis.
