Abstract
The inheritance of elongating ability under submergence in floating rice was studied using a cross Tan-ginbozu .times. Aswina: Tan-ginbozu is a mutant deficient in gibberellins and Aswina is a common floating variety of rice from Bangladesh. Internodal elongation of F1 plants under submergence showed incomplete dominance. Ability of internodal elongation can be explained in terms of complementary genes, one controls gibberellin production and the other controls responsiveness to ethylene.
