Sažetak
The genetic improvement of soybean cultivars considerably contributes to advances in production and food processing industry by developing high-yielding and high-quality cultivars. In this study, agronomic performance of new developed soybean elite lines and standrads were compared in order to evaluate the achieved genetic advance. The reseraches were conducted at the experimental field of the Agricultural Institute Osijel (Croatia) from 2005 to 2008 year. Experimental material consisted of 135 genotypes, as follows: 18, 52, 65 genotypes into maturity group 00, 0 and I, respectively. Tested elite lines were developed by different crossing within the Institute's soybean breeding program. Standrads were Institute's released cultivars that have grown in commercial production in Croatia. Biometrical analysis indicated on realized genetic advance in grain yield, as well as protein and oil content in seed of domestic soybean germplsm. Additionally , many tested elite lines had good stability in quantity and quality of grain, wide-general adaptability and high tolerance to major pathogens affecting soybean production in our country.Likewise analysis of triaciylglycerols (TAGs) showed that in oil of the best elite lines were LLL (19.5%), LLO (17.3%), LLP (13.8%), and LOP (12.5%), having the desired fatty acid profile. Acieved genetic advance in soybean considerably will contribute to further improving and increasing soybean production as well as production of safe poduct high functional value for consumers. Further genetic improvement of soybean will be based on the modern breeding strategies including combination of conventional breeding methods and recent chemical, biochemical, fitopathological and molecular analyses.
