A new spontaneous phenotype of the rice cultivar 'L-202' was found. Mendelian analysis indicates that it is a monogenic, recessive mutant. Its distinguishing features are: dark blue-green colour, short and narrow leaves, high tittering and relatively short height. The objectives of this study were: to characterize it, to determine if it is heritable and if so, its genetic basis. Its distinguishing features are: dark blue-green colour, short and narrow leaves, high tittering and relatively short height. Selfing the new phenotype resulted in a uniform progeny, with the traits of the parent plant ("wild type"). Crossing the new phenotype with the normal 'L-202' cultivar resulted in a uniform F(1) hybrid generation, with the wild type. The F(2) generation showed a mendelian seggregation which did not depart significantly from three normal plants : one new phenotype. It is concluded that it is a monogenic, recessive mutant.
