To determine the general and specific combining ability of the parental lines, five restorers and four male sterility lines were selected as lines and testers respectively. Nine parental lines were crossed in a Line × Tester crossing system in year 2005 and the eight F1 hybrids and their six parents in Randomized Complete Blocks Design (RCBD (in two replications for yield, yield components and major qualitative characters. The effect of GCA was negative and significant for grain yield in line No.2 (Sepidrood), and in line SA14R, it was positive and significant for grain yield. The effect of SCA was positive and significant for grain yield in four hybrids of IR58025A/IR62030R, IR79124A/ SA13R, IR79124A /SA14R and SA15A /Sepidrood. Two hybrids (IR79124A/ SA13R and IR79124A /SA14R) had the highest grain yield with 10.4 and 11.5 t/ha repectively. Thes combinations were recommended for hybrid seed production in of Gilan province.
