AB  - A cross was made between ERINMO 14 and OGIDE DWARF representing a cross between a cultivar with brown caryopsis and another with white caryopsis, respectively. The F<SUB>1</SUB> seeds were brown showing dominace of the brown character state. Results from the F<SUB>2</SUB> show that caryopsis colour is conditioned by a set of duplicate genes giving rise to 5 character states: Dark brown, brown, light-brown, dirty white and pure white. These character states can be explained on the basis of duplicate gene interaction with dosage effect. The ripened-hull colouration was found to be dependent on colour of the caryopsis such that spikelets with brown caryopses had brown ripened-hull while spikelets with white caryopses had straw ripened-hull. The implication of these findings for rice improvement are discussed.
