In 2002 and 2003, four cms lines (S-8 682, P-58 626, SS-1 662, SS-1 664) and two R lines (ES and 42) of sweet sorghum were studied for general combining ability for dry matter content in stem juice and plant height. Combining ability was tested by the line x tester analysis. Regarding the cms lines, the best combiner for the dry matter content in stem juice was P-58 626 in both years. The best combiner for the plant height was SS-1 662, again in both years. Regarding the R lines, the line ES was superior in both characteristics and in both years. The crosses S-8 682 x ES and S-8 682 x 42 showed highly significant SCA values for dry matter content in stem juice in the first and second year, respectively. The highest SCA values for plant height in the respective years were shown by the crosses P-58 626 x ES and SS-1 664 x 42. Regarding the expression of dry matter content in stem juice, testers had a higher contribution in the first year and lines in the second. Regarding the expression of plant height, lines had a higher contribution in the first year and testers in the second.
