Plant breeding or genera, the hybrid embryo may abort before maturation. If this does occur the embryo resulting from an interspecific or intergeneric cross can sometimes be rescued and cultured to produce a whole plant. Such a method is referred to as Embryo Rescue. This technique has been used to produce new rice for Africa, an interspecific cross of Asian rice "(Oryza sativa)" and African rice "(Oryza glaberrima)". Hybrids may also be produced by a technique called protoplast fusion. In this case protoplasts are fused, usually in an electric field. Viable recombinants can be regenerated in culture. Chemical mutagens like EMS and
Saluria inficita the plants show dried up shoots and turn yellow. Damage can controlled by hand picking, pheromone usage, light traps and usage of chemical insecticides such as carabaryl, methyl parathion, phosphomidon or dimethoate. Saluria inficita Saluria inficita, the white stem borer, is a moth of the family Pyralidae. The species was first described by Francis Walker in 1863. It is found in India and Sri Lanka. Its caterpillars are pests of "Eleusine coracana", "Oryza sativa", "Setaria italica" and "Zea mays". The adult has brownish wings. A pale white band runs along the margin of forewings.
