AbstractThe cotton (Gossypium hirsutum L.) necrotic leaf-spot mutation is due to a single recessive gene. Cytologically the necrotic leaf-spot mutant affects the development and necrosis of leaves associated with the changed staining pattern, contraction and collapse of palisade and spongy parenchyma cells sequentially. The scanning electron microscope revealed that the stomata are also involved or affected by necrosis. The mutation exhibits a slightly deleterious effect on pollen viability, but not on the viability of the embryo.
