Mass selection with controlled pollination for heading, resistance to early bolting, fewer frame leaves relative to head size and few cover leaves, was applied for three cycles in four Greek open‐pollinating populations (OPPs) of cabbage in nil‐competition conditions (honeycomb method). The cycle 0 OPPs with their respective cycle 3 OPPs were tested under competition conditions (growers density), in two successive years, to assess the selection response for heading, resistance to early bolting, number of cover leaves and yield. In most cases, the selection response was significant at P = 0.01 or even at P = 0.001. For example, the mean increase of yield estimated over all OPPs across 2 years was 36%, without any undesirable changes in dry matter and soluble solids contents.
