The main objective of the present study was to estimate the combining ability for some new white maize inbred lines. The work of this investigation was carried out in 2018 and 2019 summer seasons. In the first season of 2018, thirteen inbred lines were used as females and three testers were used as males, viz SD 7, SK 12 and SD 1193 at Sids Station. In the second growing season of 2019, all the 39 F1 top crosses along with three commercial check hybrids i.e.; SC 10, SC 128 and SC 2031 were evaluated at Sids and Sakha Agriculture Research Stations. Obtained results could be summarized as follows; mean squares due to crosses and their separating into lines, testers and line x tester exhibited highly significant for all studied traits, except line x tester for ear diameter. The non-additive gene action played a major contribution in inheritance for plant height, ear height, ear length and grain yield. seven inbred lines; L1, L2, L4, L5, L7, L9 and L13 were desirable significant of GCA effects for grain yield. The top crosses; L2 x T1, L4 xT1, L5x T1, L7 xT1, L8 x T2, L9 x T2, L11 x T2, L12 x T2, L13x T2, L2 x T3, L6 x T3 and L10 x T3 had positive and significant of SCA effects for grain yield. Two crosses; L9 x T2 (39.576 ardb/fad.) and L13x T2 (39.915 ardb/fad.) had significant and out yielded than the highest check SC 2031 (35.049 ardb/fad.).
