Crosses of 40 maize inbred lines with five tester lines, KL17/2-5, K74/1, K1264/1, B73 and MO17, and 10 crosses among tester lines were evaluated in two locations (Karaj and Gorgan) in 2004. Specific combining ability of each line was estimated according to line tester analysis. The highest yields of 11.200 and 11.08 tha-1 were produced by crosses of K3615/2, a late synthetic derived line, with MO17 tetster line and KLM7610/1-13, a CIMMYT germplasm originated line with B73 tester line, respectively.Good combining ability revealed in crosses between inbred lines originated from CIMMYT germplasm, firstly with MO17 and then with B73 tester lines,and inbred lines originated from late synthetic variety with both testers. Results of this study indicated that, in addition to Lancaster Sure Crop (LSC) and Ried Yellow Dent (RYD), there might be two more new heterotic groups in Iranian maize germplasm. LSC CIMMYT germplasm and RYD x Late Synthetic, could be promising heterotic patterns.
