The collaboration and interchange of breeding materials between breeding programs worldwide is important and necessary to increase the amount of genetic diversity by incorporating unique exotic germplasm into existing domestic germplasm. The objective of this study was to measure and compare the agronomic performance of 15 soybean cultivars released by the Agricultural Institute Osijek (Croatia) (OS-cultivars) and 15 cultivars released by the University of Guelph (Canada) (CA-cultivars) in Croatia. Based on the comparison, parental combinations could be designed to introgress exotic germplasms from the CA-cultivars into Croatian. Agronomic performance was determined in field trials that were conducted at the experimental field of the Agricultural Institute Osijek during the period from 2002 to 2005. Quantitative traits were measured and analyzed for maturity, grain yield components, level and stability of grain yield, adaptability, lodging resistance and field tolerance to Peronospora manshurica. The results indicated higher agronomic performance of OS-cultivars compared to CA- cultivars. However, comparison of yield is only tentative because all but one OS cultivar were later maturing than the CA-cultivars. Among 15 tested CA-cultivars, five cultivars (OAC Millennium, OAC Champion, OAC Bayfield, OAC Auburn, OAC Wallace) were identified as the most favorable for parental combinations in hybridization with OS-cultivars. The results of this study will enable strategic incorporation of diversity from exotic Canadian germplasm into the domestic Croatian germplasm to develop segregating populations from which new, genetically more diverse improved soybeanline, could be released. |
