A comparative study to determine the degree and direction of linear association (Y = a + mX) among yield and yield components of two cultivars of cabbage, namely Fieldwinner and KK Cross, showed high positive linear correlation between plant weight and head width (r = 0.84 for ‘Fieldwinner' and 0.90 for KK Cross; P < 0.01). The associations between yield parameters for the two cultivars differed. While head width and head solidity negatively correlated (r = -0.86) significantly (P < 0.05) in cv. Fieldwinner, the association (r = -0.01) was insignificant (P > 0.05) in cv. KK Cross. In both cultivars, however, head shape index increased with an increase in all the other parameters. Head width, head length, non-wrapper leaf weight, head weight and yield showed positive correlation in cv. KK Cross. Head yield was not significantly (P > 0.05) different between the two cultivars. Cultivar Fieldwinner produced elongated head, which were comparatively lower in weight.
