A diallel cross, including reciprocals, of seven divergent cabbage cultivars was examined for the combining ability in the lengths of inner and outer stems. These properties affect the appearance and quality of the plant, both of head alone and of the whole plant. The cultivars Kbose, Ditmar and SM-10, i.e. cultivars Pourovo cervene, Kopenhaski and SM-10 were good general combiners for the length of the inner stem, i.e. the length of the outer stem, respectively. According to these results it can be concluded that high heterosis may be obtained by increasing the number of cultivars possessing high GCA values in the crossing pattern. This would produce combinations with the largest number of desirable genes. In this study, heterosis for the length of the outer stem occurred as many as 30 times while heterosis for the head diameter occurred only 18 times.
