Mladenov, Velimir
This research presents the results of the examination of 94 genotypes of wheat (Triticum vulgare L.) and one genotype T. Spelta L. (Nirvana) and T. Compactum Host (Bambi) grown during the two vegetation season (2011/2012 and 2012/2013) at two locations (Novi Sad and Sremska Mitrovica). The phenotypic markers that were examined were plant height, spike length number of grains per spike, mass of thousands seeds and yield. The basic statistics average and coefficient of variation were shown, while the main effects and multiplicative interaction model (AMMI) was used for the analysis of the genotype interaction and the environment. The interdependence of the investigated traits was determined by analysis of the indirect correlation coefficients. Molecular analysis was consisting of used plant material with 28 molecular markers - microsatellites. The results showed the statistically significance of the main effects of the genotype on the phenotypic variability in all investigated traits. Indirect correlations have established significant correlation coefficients among some of the examined properties. A detailed analysis of the results found that only the gwm631 marker exhibited a marker-trait relationship with all five investigated traits. In comparison to the classical breeding methods, the markers assisted selection shortens the process of evaluation and selection of parental couples. In this sense, molecular markers, in addition to the experience of breeders, are indicators of the right direction in the key steps in the choice of parents.
