The inheritance of the ability of cotton seeds to germinate at low temperatures was studied in the F1 hybrid generation. Reciprocal crosses were made in 6 different combinations, and the hybrids were compared to the selfed parents of each cross. Germination tests were conducted at 12-13[degree]C and at 140C, and germinating seedlings were counted by 3 different assessment methods. The performance of the hybrids was either intermediate or showed partial or almost complete dominance. A strong maternal influence was found, which might be explained by the effect of the fuzz and the nature of the seedcoat. Conducting the test at 12-13[degree]C was found to be more efficient than at 14[degree]C in differentiating between varieties or hybrids in respect to this property.
