The objective of the experiment was to screen Cucumis melo L. inbred lines for high potential general combining ability and potential hybrids combinations for F1 hybridization. The experiment was conducted as a randomized complete block design (RCBD) with 29 treatments [21 hybrid combinations, control (TL3 hybrid) and seven Cucumis melo L. inbred lines I6], each with three replicates. Estimating the specific combining ability (SCA) of Cucumis melo L. inbred lines for breeding of F1 hybrid cultivars was carried out at the Research and Development Center for Hi-tech Agriculture in Ho Chi Minh City. Based on the specific combining ability of yield trait and total soluble solids (Brix) content of 21 hybrid lines from seven inbred lines following diallel method (Griffing 4 model), four potential hybrid lines (H41.6 x H58.6, H53.6 x H77.6, H32.6 x H41.6 and H53.6 x H58.6) yielded 10% higher than the control variety and gave fruits of oval shape, even fruit-net and low diseases infection.
