Weakness of F(1) plants is frequently found in hybrids between strains of Oryza breviligulata (wild) and O. glaberrima (cultivated rice) endemic to West Africa. A set of two complementary dominant weakness genes, W(1) and W(2), was found to control the observed F(1) weakness. Many breviligulata strains had W(1), while most of the glaberrima and semi-wild strains had W(2) or were free of both. In the weak F(1) plants, tissue differentiation in adventitious roots seemed to be disturbed. Modifier… CONTINUE READING
