Abstract
In a study of an intervarietal cross of hollyhock (Althaea rosaeaea heterosis was observed for plant height, number of flowers on main stem and side branches, flower size and flower weight. The mean values of F2 hybrids were, in general, lower than F1 hybrids but transgressive segregation in favourable direction was observed in all characters in F2 generation.
